The LaserCap is a home-use medical device indicated to treat hair loss in men and women with androgenic alopecia. It is a light and flexible cap, lined with laser diodes, and designed to be worn discretely underneath most hats. LaserCap is powered by a portable and rechargeable battery pack, and when turned on, it illuminates your hair follicles with 650 nm red light. This specific kind of light can be absorbed by the cells of your hair follicles where it is converted into energy that is used to promote hair growth. This is a treatment called Low-Level-Laser Therapy, or LLLT, which has been shown in many high quality studies to be effective at treating thinning and balding due to androgenic alopecia.
