Laser caps, also known as low-level laser therapy (LLLT) caps, are a type of hair loss treatment that uses red and near-infrared lasers to stimulate hair growth. The lasers work by increasing blood flow to the scalp, which nourishes hair follicles and promotes hair growth.
Laser caps have been shown to be effective in treating a variety of types of hair loss, including androgenetic alopecia (male-pattern baldness) and alopecia areata (patchy hair loss). Laser caps are also a safe and non-invasive treatment option, with no known side effects.
