14 – Hair growth lasers are harmful?
Hair growth lasers are Low Light Laser Therapy. LLLT which is only half watt power, as low as a night lamp. These cannot cause any harm. The US FDA has issued a new classification for the LLLT Lasers and approved them to be safe. In addition to the growing hair all patients have at least 30% more hair follicles that are sleeping. The laser induces photo stimulation of the mitochondria in the sleeping hair follicle cells and recruits them back into growth phase, adding new hair without a transplant. Laser also displaces the nitric oxide out of the cells and allows more oxygen to diffuse in. Plus the NO released has angiogenetic potential leading to formation of new blood vessels in the scalp.
