What is Laser Hair Therapy?

Laser hair therapy is the use of low level laser therapy (LLLT) in treating the genetic forms of hair loss common in men and women, androgenetic alopecia or pattern balding. LLLT is intended for men and women with thinning hair or pattern baldness caused by a hereditary condition.

History of LLLT as a hair loss therapy

Low level laser therapy has been around since the 1960s.  During the 1960s, researchers from NASA first noticed the benefits of exposing plants to LED and cold laser light to grow them in space. The researchers discovered that LLLT indeed accelerated plant growth and experimented with human tissue. They discovered that LLLT also helped speed up the healing time of wounds during space missions.  Since then, LLLT has been discovered for a vast array of medical uses to stimulate cellular activity.  LLLT has shown beneficial effects for a variety of medical conditions such as wound healing, nerve regeneration, joint pain relief, stroke recovery, and the prevention and treatment of mucositis. LLLT devices that emit low power coherent monochromatic red light have been developed for various skin conditions, including hair growth.

LLLT was first accidently discovered for hair growth by the Hungarian researcher Dr. Endre Mester in 1967. Dr. Endre was doing cancer research on laboratory mice to see if LLLT caused cancer. In one of his experiments, he divided two groups of mice. One group received low level red laser at a wavelength of 694nm. The other group was not exposed to any light treatments. Although the exposed mice didn’t get cancer, he discovered that those mice were able to grow hair back quicker than the unexposed mice. The discovery was named laser biostimulation.

How does Laser Hair Therapy regrow hair?

Hair growth cycle consists of three phases: growth (anagen phase), resting (telogen phase) and shedding (catagen phase).  When used with a LLLT device, light beam irraiates photons into scalp tissuse, increasing blood flow in the scalp and stimulate metabolism in catagen or telogen follicles, resulting in the production of anagen hair. This requires light of a certain wavelength, specifically between 630 to 670 nanometers.

LLLT causes 3 things to happen when light beam penetrates the scalp:

  • The photons of light act on cytochrome C oxidase leading to the production of adenosine triphosphate (ATP). This is converted to cyclic AMP in the hair follicle cells, releasing energy and stimulating metabolic processes necessary for hair growth.
  • Release of nitric oxide from cells leads to increasedvascularisationto the scalp distributing nutrients and oxygen to the hair roots.
  • LLLT work to counteract the negative effects of the DHT hormone by stimulating the cellular metabolism involved in hair growth. DHT is the leading cause of genetic balding and is the cause of male and female pattern baldness.

What are the benefits of laser therapy for hair loss?

LLLT for hair loss has many benefits. Hair follicles receive more nutrients, which encourages hair growth and increases the strength and thickness of existing hairs.

  • LLLT is painless
  • LLLT is noninvasive (non-surgical)
  • LLLT can be used in both men and women
  • There is safe and no adverse effects have been reported
  • LLLT is relatively inexpensive
  • LLLT requires minimal time commitment
  • LLLT helps stop hair loss
  • LLLT helps rejuvenates damaged follicles
  • LLLT helps to regrow hair and increase existing hair strength and thickness

In clinical studies, improvement is reported in at least some users after 12 to 26 weeks of use, with reduced hair fall and noticeable hair growth.  Hair growth occurs on the top of the head/crown and along the hairline of forehead.

PORTABLE LASER COMB VS LASER HELMET VS PROFESSIONAL IN-CLINIC LLLT HAIR GROWTH MACHINE

How is low level laser hair therapy administered?

Since the discovery of LLLT for hair growth, there have been hundreds of LLLT devices invented for hair regrowth. Most fall into 3 categories, portable laser combs, portable laser helmets, and professional LLLT machines for clinic use.

PORTABLE LASER COMB

Portable laser combs are devices that emit a low powered, usually battery operated light beam onto the scalp for promoting hair growth. The comb deliver light energy to the hair follicles and help thicken and promote hair growth.  There are many manufacturers or distributors of these combs, some of these include Hairmax, Wellay, Power Grow, Lifemax, Folinex, just to name a few.  Laser combs cost around $200-300.

In 2009, in a 26-week, randomized, double-blind study done on 110 patients, researchers concluded that the HairMax LaserComb, one of the earliest laser devices sold to treat hair loss, was an effective treatment for male pattern baldness. The LaserComb group showed significantly greater increases in hair density compared to the placebo (sham device) group.

Image Above: Male and female pattern hair loss before and after lasercomb treatment. Global photographs of a female subject, at baseline (a) and after 26 weeks (b) of the 12-beam lasercomb treatment. Macrophotographs of a male subject, at baseline (c) and after 26 weeks (d) of the 9-beam lasercomb treatment. Increased hair count through conversion of vellus or intermediate follicles to active follicles producing terminal hair (ovals) or resting telogen to active anagen follicles (rectangles) is highlighted.

“We observed a statistically significant difference in the increase in terminal hair density between lasercomb- and sham-treated subjects. No serious adverse events were reported. Our results suggest that low-level laser treatment may be an effective option to treat pattern hair loss in both men and women. Additional studies should be considered to determine the long-term effects of low-level laser treatment on hair growth and maintenance, and to optimize laser modality.”

If one is thinking about buying a laser comb, make sure alopecia hasn’t reached an advanced stage. It will not work on bald heads, but it can stimulate and thicken existing hair follicles that are not already too damaged.  There are mixed reviews on laser combs, and it’s not guaranteed to work on everyone.

PORTABLE LASER HELMET

Portable laser helmets work similarly to portable laser combs. The main difference is that you wear a cap with cool LED infrared laser diodes instead of combing your hair with them. Generally, laser helmets are more expensive as they have more LED diodes, usually around 50 to 80 compared to 7 to 12 on most laser combs.  A portable laser helmet can cover a larger area in one single session, and it easier to use because you simple put it on your head.  Because of the larger area and many more LED diodes, portable laser helmets are considered more effective in combatting thinning hair. There are also many manufacturers and distributers of laser helmets.  The most popular ones are iRestore, iGrow, and Capillus.  Portable laser helmets cost $500 to $1000 or more.

CONCLUSION

LLLT Laser therapy has been proven to treat hair loss. Portable devices like laser combs have been proven to work to help stimulate hair growth.  Portable laser helmets are the next upgrade to this technology, with more LED diodes and larger coverage area.  However, for best results and professional advice, we recommend going to a laser clinic such as hairlossclinic.ca which specializes in laser hair loss therapy, before purchasing your laser comb or helmet.
