Low-level laser treatment (LLLT) is a medical treatment for hair loss that uses laser light to stimulate the growth of new hair. LLLT is a non-drug therapy that works by activating the cells responsible for hair growth, called stem cells. The therapy has no side effects and it is painless, so it is a good alternative to hair transplant surgeries. FDA has approved LLLT as a medical treatment for hair loss associated with pattern baldness. The laser helmet stimulates new hair growth in men and women with a variety of types of hair loss.
The device used for low-level laser treatment for hair loss is a helmet composed of four light-emitting diodes (LEDs) connected to a computer chip. The patient wears the theradome laser helmet, and the doctor adjusts it until the LEDs produce wavelengths that are absorbed by cell membranes in hair follicles. When this happens, stem cells within the follicle divide and multiply, creating new hair fibers. It is believed that the light triggers the production of adenosine triphosphate (ATP), which stimulates stem cells. An increase in ATP production also increases energy levels and improves blood flow throughout the body.
Some of the commonly used schedules are:
Low-level laser therapy treatment areas include:
Skin: Low-level laser therapy for your skin includes treating conditions like psoriasis, acne, eczema, stretch marks, and warts. Low-level lasers can also help to tighten the muscles in your face giving you a younger look.
Hair: Low-level laser therapy for your hair reduces the appearance of thinning and dry skin. It helps to improve blood circulation in the scalp and stimulates the growth of thicker and stronger hair.
LLLT is used to treat hair loss in both men and women that stem from a variety of causes, including the following:
Besides hair loss, low-level laser treatment is beneficial in treating several conditions including
