Low-level laser therapy (LLLT) is a form of alternative medicine that applies low-level (low-power) lasers to the scalp to encourage hair growth.  It can be used alone or in conjunction with other treatments such as medications, PRP therapy or hair products.

Hungarian physician and surgeon Endre Mester accidentally discovered that low-level laser light could regrow hair during an attempt to replicate an experiment that showed that such lasers could reduce tumors in mice. The laser he was using was faulty and wasn’t as powerful as he thought. Although it failed to affect the tumors, he noticed that in the places where he had shaved the mice in order to do the experiments, the hair grew back faster on mice he treated compared with the placebos. He published those results in 1967.

Since then studies have found that LLLT is able to accelerate blood flow, enhance synthesis of protein, DHA, fibrocyte, and ATP.

The laser cap stimulates mitochondria to generate ATP.

Laser light penetrates the scalp at a depth of 3-5 mm and reach the base of a hair follicle. By healing the base of hair follicles, this proprietary laser technology stimulates the mitochondria of hair cells. The mitochondria then produce cell energy–ATP, which is used by hair follicles.
