What is laser hair growth treatment?

Laser hair growth treatment uses low-level lasers to emit light energy into the scalp tissues and feed the weak hair follicles. Once the follicles absorb the energy, the body triggers biochemical reactions (similar to photosynthesis in plants) that support the natural hair growth process. This procedure is called low-level laser therapy (LLLT), and its hair-stimulating effects were first discovered by Endre Mester in 1967.
