Advance level laser therapy is a safe form of light/heat treatment used in the treatment of genetic hair loss or pattern balding in men and women. Low level laser therapy (LLLT) uses devices with diodes that emit red light (wavelength 630-670 nanometers).
How is laser hair therapy supposed to work?
The hair growth cycle consists of three phases: growth (anagen phase), resting (telogen phase) and shedding (catagen phase). Hair loss in androgenetic alopecia depends on a testosterone derivative in the skin, dihydrotestosterone (DHT). Low level laser therapy is believed to increase blood flow in the scalp and stimulate metabolism in catagen or telogen follicles, resulting in the production of anagen hair. In theory:
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 & stimulating metabolic processes necessary for hair growth.
Release of nitric oxide from cells leads to increased vascularisation to the scalp distributing nutrients & oxygen to the hair roots.
Excessive build-up of DHT is prevented.
All the above factors help to control hair loss and also stimulate the pre existing hair to become healthier.
Benefits of laser therapy for hair loss
Low level laser therapy can be used in both men and women
It is completely non surgical.
There is no such thing as recovery time after the therapy.
No adverse effects have been reported
It is clean and painless
Low level laser hair therapy is relatively inexpensive
It requires minimal time commitment, only 20 to 30 mins per session
