What is laser hair growth?

There are a variety of different gadgets available on the high street that offers LLLT therapy to promote hair growth.  LLLT (low-level light therapy) is a treatment that utilizes lasers, or light energy below a specific energy threshold and within a specific wavelength, to help promote hair growth.
The light source used for these products can range between laser and LED devices, the laser devices used are referred to as cold lasers as they produce no heat and are therefore safe to use and will cause no damage to the skin or hair follicles.

What is the clinical evidence to show laser hair therapy is effective?

Physicians have varying views on whether or not low level laser therapy is effective. While some physicians reject its use entirely, others believe that low level laser therapy can provide benefit for some men and women suffering from androgenic alopecia (genetic baldness). It has also been suggested that it may assist a hair transplant patient’s postoperative wound healing process and expedite hair growth.

Results of a double-blind, sham device-controlled, randomised multicentre trial have shown that 110 male patients with Norwood-Hamilton classes IIa-V androgenic alopecia, exhibited a significantly greater increase in mean terminal hair density compared with subjects in the sham device group after 26 weeks therapy with the laser light comb (p <0.0001).
Macro photographs of the scalp were captured of all of the subjects at the beginning and end of the trial and sophisticated hair counting software was used to determine the number of normal-sized hairs that grew as a result of using either device.
Hair growth in subjects who used laser therapy increased by an average of 19 normal-size hairs per square centimeter, while it decreased by an average of 7 normal-size hairs per square centimeter in those using the placebo device.
Consistent with this evidence for primary effectiveness, significant improvements in overall hair regrowth were demonstrated in terms of patients’ subjective assessment (p < 0.015) at 26 weeks over baseline.
Treated subjects also experienced more favourable hair attributes, such as thicker, shinier, and more manageable hair compared to those who used the placebo device.
No statistical improvement was noted on global investigator assessment.
Similar study results have been reported in a double-blind device controlled study in women with androgenic alopecia.
In a second study of 103 males and 122 females with pattern alopecia that completed the study, HairMax® LaserComb (with 12, 9 and 7 beams) was reported to result in increase in terminal hair density compared to similar trial subjects treated with a sham device.

Trials are underway to study the efficacy of LaserCap™ (Transdermal Cap, Gates Mills, Ohio), TopHat 655 Rejuvenation System (Apira Science, Newport Beach, California) and Erchronia ML Scanner (Erchronia Corporation, McKinney, Texas) in pattern alopecia and other forms of hair loss.

However, published trials of low level laser light have been criticised as not being independent and anedotal individual reports of using these devices appears disappointing.

How does laser hair growth work?

LLLT has been shown to promote hair growth in both men and women with androgenetic alopecia. Research indicates that LLLT is absorbed into the cells, and this triggers enhanced cellular activity. The LLLT is thought to make aging cells more active, which works to increase their effectiveness in hair growth however; there is currently not enough research to be sure how the treatment works.
