LLLT (Low-Level Light Therapy) is a non-invasive hair restoration treatment that uses low-level lights to stimulate hair growth, in particular the red wave length of light. The exact mechanism by which LLLT works to promote hair growth is not fully understood, but it is believed to work through several different mechanisms:
Increasing blood flow: LLLT is thought to increase blood flow to the scalp, which in turn improves the delivery of nutrients and oxygen to the hair follicles. This can help to promote hair growth and improve the overall health of the scalp.
Stimulating cellular metabolism: LLLT is believed to stimulate cellular metabolism in the hair follicles, which can help to promote the production of new hair cells and improve the rate of hair growth.
Reducing inflammation: LLLT has been shown to have anti-inflammatory effects, which can help to reduce inflammation in the scalp and improve the health of the hair follicles.
Increasing the production of ATP: LLLT is thought to stimulate the production of ATP (Adenosine Triphosphate), which is the primary source of energy for cells in the body. This can help to improve the health and function of the hair follicles, leading to improved hair growth.
Overall, the exact mechanisms by which LLLT promotes hair growth are still being studied and are not fully understood. However, there is evidence to suggest that LLLT can be an effective treatment option for hair loss in some individuals, particularly when used in conjunction with other hair restoration therapies.
It is important to note that there is a wide range of devices on the market, many are unpowered and do not emit enough light to adequately penetrate down to the level of the hair follicle.
