This hair regrowth laser device uses low-level laser therapy (LLLT) to stimulate hair follicles and promote regrowth. It is a non-invasive and painless treatment that can be used in the comfort of your own home. The laser device emits red light that penetrates the scalp, stimulating blood circulation and revitalizing dormant hair follicles. With consistent use, you can expect to see visible improvements in hair density and regrowth.
