Red or near-infrared laser light has been used for a while to promote and stimulate cellular activity all over the body. In the past few years, it has been proven that low-level light therapy (LLLT) also stimulates the growth of hair in men and women.
Lasers were discovered in the 1960s, and their uses have been constantly evolving within the medical field. They have been used in various medical treatments such as stroke recovery, wound healing, nerve regeneration, and even joint pain relief. LLLT devices that can be used at home have been invented to help with various conditions, including hair restoration and growth.
The benefits of lasers and hair growth were actually discovered by accident in the late 1960s by a Hungarian physician, Endre Mester. Dr. Mester was experimenting on mice with a low-power ruby laser to test the carcinogenic potential of lasers. To conduct the experiments, it was necessary to shave the mice. The lasers did not eventually cause cancer in the test mice, but they actually accelerated hair growth in the shaved areas of the animal. This was the very first recorded case of photo biostimulation using a low level laser, and it opened up a whole new path in the field of hair restoration. Photo biostimulation is a hair growth process using LLLT that is comparable to photosynthesis, which causes growth in plants.
