Low-Level Laser Light Therapy
Low-Level Laser Light Therapy (LLLT)
There are many LLLT devices available on the market as hair lasers that have acquired US FDA clearance used to treat hair loss.
A low dose red (~650nm wavelength) laser light is emitted onto the scalp and improves blood flow to the hair follicles, reducing inflammation involved in hair loss and increasing hair follicle activity.
There are various ways to apply LLLT – a home use device usually in the form of a cap or helmet or comb, or an in-clinic device with higher power to treat patients with severe hair loss or post-hair transplantation patients.
Various treatment regimens exist for different LLLT devices ranging from weekly to daily use. Reading the manufacturer’s recommendations would ensure safe usage of the device.
