The hair growth industry is heavily utilizing laser hair growth caps to treat hair loss of all kinds. These upscale devices are FDA-cleared to be both safe and effective for both men and women ages 18 and older. Kiierr laser caps use 272 medical grade laser diodes to emit the low level laser (light) therapy technology into the scalp tissue. This treatment stimulates blood flow in the scalp resulting in cell regeneration and hair follicle regrowth.
