Low level laser therapy is a safe form of light treatment (a type of ) 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.
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), available as:
in-salon hoods or overhead panels
bonnet or head caps
Each session takes about 30 minutes. Patients sit under a light-emitting device and are able to watch movies or read magazines. It’s that simple and easy!
