What is low dose laser therapy?
Low level laser therapy is a safe form of light/heat treatment under investigation for a variety of health indications. It is being used to treat the genetic forms of hair loss common in men and women, androgenetic alopecia or pattern balding.
Low level laser therapy is also called red light therapy, cold laser, soft laser, biostimulation and photobiomodulation.
Androgenetic alopecia can affect up to 70% of men (male pattern balding) and 40% of women (female pattern balding) at some point in their lifetime. While men typically present with a distinctive alopecia pattern involving hairline recession and vertex balding, women normally exhibit a diffuse hair thinning over the top of their scalps. For both men and women, losing their hair is a frustrating experience. The current treatment standard for pattern balding is therapy with minoxidil and finasteride, with hair transplantation as a surgical option. However, low level laser treatment for hair loss is now also promoted as a safe alternative or additional treatment.
Laser therapy used for hair loss treatment depends on devices that emit a light that can penetrate the scalp. Excimer (308 nm), helium-neon (632.8 nm), and fractional erbium-glass (1550 nm) lasers have been used. Low level laser therapy (LLLT) uses devices with diodes that emit red light (wavelength 630-670 nanometers), or infrared radiation, available as:
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 Hair Loss Treatment blood flow in the scalp and stimulate metabolism in catagen or telogen follicles, resulting in Best Hair Transplant the production of anagen hair. In theory:
