There is no fixed defined age for graying in human beings. The first silvery strands usually become visible around the age of 30 for men and age 35 for women. However, in some people graying can show up as early as high school and for some as late as in the age bracket of 50s. However, one thing is certain. Premature graying is on the rise.

The human head has about 100,000 of teardrop-shaped cavities called follicles, each capable of sprouting several hair in a lifetime. The pigment in the hair shaft is generated from cells at the base of the root of the hair. Keratinocytes build the hair from the bottom upwards, stacking atop one another. These eventually dye leaving behind mostly keratin, a colorless protein that gives hair its texture and strength. While the keratinocytes construct hair, the neighboring melanocytes manufacture a pigment called melanin. This pigment is delivered to the keratinocytes via melanosomes. There are two shades of hair melanin; eumelanin, which is dark brown or black in color and pheomelanin, yellow or red in color. These two combine in different proportions to create a vast array of human hair colors. At any given time, around 80 to 90 percent of the hair of an individual are in an active growth phase. This growth may last for two to seven years. At the end of this stage, the follicle shrivels, the keratinocytes and melanocytes undergo programmed cell death and the follicle enters a resting phase. This resting phase is marked by hair fall.

The scientists at Harvard proposed that a failure of melanocyte stem cells (MSC) to maintain the production of melanocytes could cause the graying of hair. As we get older, melanocytes start producing less pigment. Gradually, there arises a stage when there is no pigment at all in the hair. This gives the hair a transparent shade. Hair that has lost most of its melanin is gray, whereas hair that has lost all of this pigment is white.

The main cause of premature graying involves heredity factors. If the parents have grayed early, there is a possibility of the same characteristic being transferred to the child through the genes. Although scientists would not like to believe, stress may be playing a role in a more gradual graying process. People today are living an extremely mechanical life. There is constant stress to meet the deadlines at office and complete household chores. This rushed life style causes excessive stress and strain that disrupts the entire body system.

Although no clear correlation has been identified between stress and gray hair, research exemplifies that stress hormones may have an impact on the activity or existence of melanocytes. Stress hormones produced either systemically or locally by cells in the follicle could produce inflammation that drives the production of free radicals. These free radicals could influence melanin production or induce bleaching of melanin. There is further evidence that local expression of stress hormones mediate the signals instructing melanocytes to deliver melanin to keratinocytes. Therefore, a disruption in that signal results in melanin not delivering pigment to the hair.

Stress, long working hours, nutrient deficient diet and excessive caffeine are common features in the life of today’s youth. These very factors could also be contributing towards the premature graying of hair. No wonder the modern generation is aging faster than the earlier generations!

Women (and men) have been trying to get rid of unwanted hair for centuries. Shaving, plucking, waxing and chemical dilapitory agents have been used by literally billions of people for thousands of years. Yet in Manhattan, the latest trend in hair removal promises long lasting, less painful results than any of these methods.

Both the trendy and not so trendy flock to the new laser hair removal treatment centers in Manhattan to receive the latest technology in smooth, hairless skin. The procedure is described as safe, using a very low level laser beam. The lasers energy enters the pigment inside the hair follicle. As the energy heats the pigment, the hairs root is destroyed but the surrounding skin remains unharmed. The follicle is also deactivated, reducing regrowth.

For most, the procedure takes from 15 minutes to just over an hour, depending on the size of the area to be treated. The process is virtually painless, with most patients experiencing a slight stinging sensation. Of course, the more sensitive the area, the more likely that some unpleasant sensations will occur. For the more sensitive areas, a topical numbing cream may be used.

Since hair grows in cycles, it may take several sessions to remove all of the hair in an area, but once the treatments are completed the results are extremely long lasting. Not only are the treatments quick and painless, but they are surprisingly affordable as well.

There are many laser hair removal clinics in Manhattan. Choose one that uses an FDA approved laser specifically designed for hair removal. Different lasers are used for different skin types, so check to see if the laser used by the clinic is right for your coloration. Make sure that your technician is certified and fully trained on the equipment being used.

Interested to join the in crowd in Manhattan and try laser hair removal? Not only will you be surprised at the great, long lasting results, but youll be in on the newest grooming craze to hit New York in decades!br

Los Angeles, CA July 27, 2004 — Melancor (www.melancor.com) leading nutraceutical researcher and developer announced the release of new information for hair care professionals surrounding the cause and treatment of thinning and graying hair.

Hair typically turns gray as a result of the natural aging process. The pigment in the hair shaft comes from cells at the base (root) of the hair. These cells are genetically programmed to make a certain amount of pigment (Melanin) starting at a specific age. At some point in the aging process, these cells start to make less pigment until the hair has little pigment at all. A white hair has no pigment, and a gray hair has some pigment but not as much as red or brown hair.

The first place people turn with graying or thinning hair is their hair care professional, said Dr. Eric Davenport of Melancor. Before now the only real treatments available were dyeing or expensive pharmaceutical treatments, many not available to hair care professionals. Melancor has developed an all natural, cost effective oral treatment that works to revitalize these dead cells that compromise hair strands. Melancors patent pending Melancor-NH proprietary blend uses a Melanin producing formula to generate Melanin throughout the body. Melancor-NH also stops male pattern baldness by blocking increased levels of DHT.

Studies indicate that a vast majority of cases of hair loss, male and female, is hereditary. The body naturally produces an enzyme called 5-Alpha-Reductase. When this enzyme reaches an imbalance, mixing with the Androgen hormone located in the scalp, it causes normal testosterone to transform into DHT. Researchers have found that certain combinations of minerals and herbal additives can attach to the 5-Alpha-Reductase in order to block the formation of DHT. Melancor-NH can halt the effects of DHT and even help the re-growth of hair follicles people had already lost.

Melancor-NH is the first proprietary all natural oral treatment designed to help men and women overcome genetic and natural aging links to gray hair and baldness, says Dr. Gregory Collaghan, Reseller for Melancor.

Melancor-HN is now being made available in large scale to hair care professionals nationwide through a special industry specific wholesale program. More details about the program can be found at www.melancor.com or by calling 1-888-769-4729.

ABOUT MELANCOR: More than 15 years ago, Melancor (www.melancor.com) was founded by doctors and nutritionists, providing quality hair and skin products such as the proprietary Melancor-NH, in nearly 20 different countries. Melancor has provided research and service to help find a solution for people who are looking for realistic solutions to their disposition to gray or balding hair.

The laser pubic hair removal procedure is roughly the same for men and women; it consists on shining the pubic region with a high energy laser beam for a very short time. This energy is absorbed by the dark pigment present in the hair follicles, disabling their ability to grow and stopping them from becoming thicker. The laser beams attack pigments, so the lighter the skin, the less damaged it gets. However, the damage received in the skin is not permanent, even if the treated region is large. Removing pubic hair by laser doesnt normally cause pain, but just a little discomfort. If you have very delicate skin in your pubic region, you should consider using a mild topical anesthetic to reduce the discomfort, but it is generally unneeded.

Types of Laser Pubic Hair Removal

There are several types of laser hair removal methods available. For instance, many people decide to eliminate all of their pubic hair, while others decide to leave a tiny portion of hair, therefore performing a partial pubic hair removal. Whether it is a complete removal or a partial one, the mechanism of functioning is the same.

There are numerous types of lasers used to remove hair like Alexandrite laser, Nd:YAG, Pulsed diode array, Aragon laser and Ruby laser. Argon and Ruby lasers are not being used anymore because their wavelength is unsafe for the skin. Of all the lasers mentioned, the most effective one is the Alexandrite laser, but it is ineffective unless you have very light skin. The pulsed diode array laser is used for medium-colored skin while Nd:YAG is used for more tanned skin.

Pricing and Sessions Required for Laser Pubic Hair Removal

Laser hair removal professionals usually charge from $200 to $600 per session, although there are a couple of factors that will alter the exact prices. The number of sessions necessary to permanently stop hair growth depends on the skin color/hair color blend of the patient, being each session much more effective if the person has a very light skin and black or very dark brown hair. The closer to this blend, the fewer number of sessions needed. It takes roughly 4 sessions at a price of around $2000 to complete the whole process.

Laser Pubic Hair Removal Side Effects

A few minutes after each session, the treated skin area may become pink or even red. It feels like a mild sunburn and usually lasts for a couple of days. You may apply some topical cream to relieve the soreness. Moreover, you shouldnt expose the treated skin to the sun within 6 weeks of your sessions to prevent further skin damage to the already sensitive skin.

The Problem with Permanent Pubic Hair Removal…

The main advantage of laser hair removal can be a disadvantage depending on how you look at it. You will not be able to groom your pubic hair again because you will no longer have hair in your pubic region. Some people choose to keep only a small patch of pubic hair by choosing to remove pubic hair only on the bikini area and areas that will be exposed outside their skimpiest swimsuit or knickers.

If you can afford the expensive cost and the slight inconvenience, you will never have to shave or wax again! You will be able to say goodbye to razor bumps, pubic ingrown hairs and pubic pimples. However, please be 100% certain that this is what you want to do for there is no turning back once you permanently remove your pubic hair with laser.br

Just because you have Gray hair doesnt mean you should use any old shampoo. When your hair goes Gray its a sign that it needs special treatment as the vital nutrients that produce the pigment for your hair color are now no longer as healthy as they use to be.

So what should you look for in a shampoo when deciding on the best treatment for your hair? Gray hair will usually be dry so you need a shampoo that will bring back the moisture in your hair as well as replace the vital nutrients that are lacking. There are many shampoos on the market that treat thinning, dry, brittle and oily hair; however there are not many that claim to treat gray hair.

If you are looking for a shampoo that is going to treat your Gray hair as well as return your hair to its natural color or at least darken it to some degree then you need to have a very specific shampoo. Do not go for a shampoo that promises to bring back your natural hair color in one or two washed as this means that the shampoo contains a lot of dye and will do nothing for the condition of your hair. Most people want a shampoo that will gradually change the color of their hair over time so that it is not too noticeable or immediately obvious.

When our hair goes gray it is because the cells in our hair follicles called Melanocytes, stop producing pigment and the result is a transparent hair. The transparent hair against your healthier darker hair gives the appearance of Gray hair. In reality the hair is not Gray but transparent. When we reach this stage its because our hair is no longer as healthy as it use to be so we need to treat it in such a way that we replace what it has lost. Although we have mentioned the main cause of the hair going Gray it is also important to remember that the lack of nutrients such as B12 and Omegas 3s are major contributors of hair going Gray.

So to treat your Gray hair you need to replace these 2 ingredients. B12 can be taken in tablet form but the Omega 3s can be found in some shampoos. The way it works is that the Omega 3 rich shampoo penetrates deep into the hair follicle to deliver unprecedented nutrition to keep the hair follicle in its original color. The oil contained in the shampoo is known as the follicle awakener and has been used by many to help prevent the onset of gray hair. Every hair must have omega 3s to grow properly.

There are products on the market that have these attributes so there is a solution to treating your Gray hair. Whether you want to get your hair color back or just look after your hair the way it is then you need the right shampoo. So make sure the shampoo you choose has these ingredients in them. Just because you have Gray hair doesnt mean it shouldnt look good.br

You can shave, pluck, wax, bleach or depilate, but the one inherent problem with unwanted hair is that is always grows back.

Laser Hair Removal, seems to be one of the only permanent solutions to removing hair in places youd rather be without.

Laser Hair Removal has been performed since the mid 90s or so. Even thought this procedure is fairly new, more efficient techniques are still being developed by researchers. Men and women the world over have found relief from unwanted hair via Laser Hair Removal. Women prefer to be sans hair in facial areas, the legs, arms, underarms and the bikini area. While men have increasingly found laser hair removal beneficial for excessive hair on the chest, shoulders and back (no more excuses for hairy backs).

Laser Hair Removal has many advantages over waxing and electrolysis, but none are as more comforting than the reduced pain factors. If you have thinker skin than you may bypass the topical anesthetic, but if you prefer not to feel any discomfort what so ever, you simply need to apply the miracle cream one hour before your Laser Hair Removal treatment and you can say ciao to pain!

Laser Hair Removal machines are well adapted to treating large surface areas, making laser treatment an excellent and more permanent alternative to conventional removal methods.

In essence, the Laser Hair Removal machines energy is absorbed by the pigment that gives hair its color. Red and near-infrared laser light propelled by the machine is strongly absorbed by brown or black hair, while red and blond hair absorbs very little infrared light. The energy of the absorbed laser light is released into the hair follicle, and therefore damaging or destroying the target tissue in the follicle. Its crucial that the correct laser intensity be used for hair removal. If the intensity is too strong, the laser beam will burn your skin. You should request a patch test to see how your skin reacts to the laser before going through a full removal.

Laser Hair Removal is ideal for almost all skin coloring. That said, darker complexions should note that the a higher level of pigmented skin tends to absorb more of the red to infrared laser wavelengths, while fair skin absorbs less of these laser wavelengths. Hence, the chances of darker complexion of burning and scaring are MUCH greater. You must discuss this serious side effect with your medical spa expert or your dermatologist.

Freedom from unwanted hair is very possible thanks to Laser Hair Removal methods. That said, Laser Hair Removal is a highly effective way of reducing hair, but like another other method its not 100 percent effective in permanently removing all unwanted hair. Some body parts such as the bikini area will require yearly Laser Hair Removal treatments to continuously reduce the hair mass and thin out hair re-growth.br

Laser hair removal is one of the newest cosmetic procedures available today. The process is to permanently remove hair from any part of your body that you wish by the use of a light at a designated wavelength, which is projected into the skin by way of a laser hand held instrument.

What the laser accomplishes, after its reached into the interior of the skin, is to focus on the hairs pigment. The laser destroys the follicle of the hair but does not damage the remaining hair tissue around it.

While laser hair removal can be quite effective and has been so for many, it is new, and, as compared with older hair removal treatments, relatively untested. What this means is that we really dont know yet just how safe or unsafe it might be and the potential for side effects. The other issue with the newness of this laser hair removal process is that no one has used it for long enough to have continuity of statistics that would indicate the rate of response to the laser hair removal treatment and the rate at which the hair grows back after each laser hair removal treatment.

Two of the most important elements to consider in qualifying potential laser hair removal candidates are skin color and hair color.

1. Skin Colour. Light skin makes laser hair removal easier to perform. Due to the lighter pigmentation, the laser hair removal results happen more quickly. Fewer treatments are required, and better, faster results are obtained. People with darker skin can be treated, but results are slower. They just have to be content with the knowledge that it will take longer to see results and a greater number of treatments are probably going to be needed.

2. Hair Colour. Laser hair removal works best on dark hair. The reason for the difference is the pigment pheomelanin, which is found only in red or blonde hair. It is very hard for a laser to penetrate pheomelanin. On the other hand, the laser goes easily through eumelanin, the pigment found in black and brown hair.

Treatment costs can add up to more than $1,000 as multiple treatment sessions may be necessary to obtain optimal results. This is largely due to the fact that laser hair removal is most effective for hair which is in the anagen phase (the growth phase). Since hair grows in cycles, not all of the hairs are in the anagen phase at any given time. Thus, more sessions are necessary to target hairs while they are in anagen.

How much and how long an individual respond to complete hair removal by laser hair removal differ from case to case. So, no hair removal clinics can guarantee 100% permanent results by a certain period. Consumers are nevertheless well advised, to consult with licensed professional and reputable laser hair removal centers.br

Laser hair removal is gaining popularity as a method of permanent hair removal. Permanent hair removal saves the time, cost and hassle of waxing, shaving or using cr?me hair removal products. The cost of laser hair removal can be high, but depends on several factors.

What is the Cost of Laser Hair Removal?

This is the most commonly asked question by people considering laser hair removal. The price depends on several factors. You should expect to have several sessions with the laser. Even in smaller areas, each follicle needs to be hit during its growth phase. This will take a few sessions, as not all follicles are ever in the growth phase together.

Although laser hair removal prices can be high, many people find the cost worth it to have the unwanted hair removed permanently. In many cases, the cost is in the range of other permanent hair removal techniques. Laser isn’t more expensive than the cost of electrolysis. Consider what you spend now for hair removal. Over time, you will save money on the cost of body waxing or depilatory products.

5 Factors Affecting the Cost

1. The size of the area being treated. The laser can be used on any area of the body, excluding the eye area. Smaller areas, such as the pubic region, require less time than larger areas, such as the legs, chest or back.

2. The area of the country where you live helps determine the cost. Sessions range from $300 to $500 per session, depending on where you live.

3. The number of sessions you will need. This will be discussed during your consultation. Four sessions is common, but it could be anywhere from three to six sessions.

4. The color of your hair and skin is a major factor in the cost of laser treatments. Because the energy from the laser is absorbed by the pigment in the hair, it’s best if your hair is darker than your skin tone. Dark hair on light skin responds best to treatment. The procedure is least effective on blonde or red hair. Several sessions will be required and the results may not be consistent.

5. The color of your skin is another factor that will affect the cost. Very dark skin isn’t a good candidate for laser hair removal. The energy from the laser is absorbed by the pigment in the skin. In extreme cases, this can result in burns or skin damage. For this reason, you should not have a suntan when you sit for laser hair removal. Avoid tanning for a month before the procedure to give your tan time to fade.

Choosing a Facility on the Cost of Laser Hair Removal

You should never choose a facility based solely on cost. This is not a cosmetic procedure, but a medical one. You want a highly trained and experienced person handling the laser. You may find discount clinics offering this service. Be suspicious of this type of clinic. A clinic with a well respected and experienced staff generally doesn’t offer deep discounts. You don’t choose your other medical care based only on cost, so you shouldn’t do this will laser hair removal either.

Choose a clinic based on the qualifications of the medical director and the experience of the staff. Look for a doctor that is Board Certified in Dermatology and who has had training and experience with the laser. The better clinics have more than one board certified doctor on staff. The atmosphere of the office should be professional.

Ask about the experience of the person performing the procedure. Most states require a physician or a RN under the supervision of a physician. Ask about the number of procedures and any adverse reactions that have occurred. If possible, speak to a few former patients about their experience.

There are many different techniques to remove unwanted hair. Some of these include waxing, shaving, coils, electrolysis and laser. Although each has its advantages and disadvantages, they all perform the same function. That is removing unwanted hair.
One such technique that has become quite popular these days is laser hair removal. This technique works by using a laser on the hair at a specified wavelength that emits a specialized light. The light from the laser is passed through the skin and is absorbed by the hair follicle. This light actually targets the melanin (colour) in the hair follicle and damages it, thereby causing the hair to fall out. Interestingly, the use of certain laser for removing hair has been approved by The Food and Drug Administration (FDA). Although the technique is popular, there are advantages and disadvantages of using this method.
Advantages of Laser Hair Removal
The laser hair removal process has advantages in that larger areas can be treated. In addition it is also safe enough to be used on all parts of the body such as the face, back, underarm, bikini line, legs and arms. Compared to electrolysis, it is less painful as the laser only causes a slight burning sensation compared to the needle prick feeling of electrolysis. Unlike shaving or waxing, laser hair removal is usually long lasting.
Disadvantages of Laser Hair Removal
One disadvantage for laser hair removal is that not everyone is the perfect candidate for this type of treatment. Those with lighter skin and dark hair have a much higher chance of permanent hair removal than grey, red or blonde hair. In addition, those with dark skin or who are tanned are also not good candidates as the laser may cause damage to their skin due to high pigment levels. The reason being is that dark hair contains a pigment called eumelanin which effectively absorbs more laser energy and therefore results in more effective destruction of the hair follicle. Due to the higher effectiveness of the treatment towards dark haired fair skin patients, it leads to fewer treatment and is therefore less costly. Other the other hand, grey, red and blonde hair contain a pigment called pheomelanin that absorbs less laser energy reducing the effectiveness of the treatment. Therefore extra treatment is required for the same effect. So before you sign up for this treatment, make sure you know the principal of this treatment. If you are not an ideal candidate, be prepared for extra treatment charges.
Laser hair removal is expensive due to the multiple treatments required. The reasons is that hair grows in a cycle that ranges from approximately 6 to 12 weeks and this is the amount of time that it takes hair to grow from the base of the follicle to the surface of the skin. As hair grows during these cycles, only a portion of the hair is being treated during this growth period with each laser treatment. Therefore multiple treatments (approximately four to eight depending upon your colour of your hair and skin) are required during this growth period. This is so that each treatment allows total coverage on all hairs during the various growth cycle. This can range from approximately a four to eight week interval. As discussed above, darked hair patients with fair skin require less treatment.
The average cost per treatment ranges from $500 and about four sessions are required. Again, this number will differ depending upon the size of the area treated and the colour of your skin and hair. To get an exact cost, a consultation on pricing is an individual process and it is best to discuss this with the laser center.
Once you have decided to undertake this treatment, make sure it is performed by an experienced laser treatment centre. Due to different state regulations, there has been varying level of compliance with laser hair removal centres and this has resulted in improper treatment by unskilled clinics. Some states require a doctor to perform the treatment, whilst for others; anyone including “unskilled” personnel can perform the treatment. Read the latest news on laser hair removal for more information. These improper unskilled clinic may result in burns (similar to sunburn), lesions, skin discolouration that can last several months, or patchy/patterned regrowth. One rule to remember is that cheaper is not always the best, so find the best laser hair removal centre around.
