How does Low Level Laser Therapy help with hair regrowth?

Low Level Laser Therapy (LLLT) is a treatment that is claimed to promote hair growth. It is also known as red light therapy or cold laser therapy. The theory behind LLLT is that the low level laser light energy stimulates the cells in the scalp and increases blood flow, which may help to promote hair growth. It is generally considered to be safe when performed by a trained professional, although some people may experience mild side effects such as scalp irritation or dryness.

ATP (adenosine triphosphate) is a molecule that is involved in the production of energy within cells. It is produced through a process called cellular respiration, which occurs in the mitochondria of cells. There is some evidence to suggest that LLLT may increase ATP production in cells, although the exact mechanism is not fully understood. One theory is that LLLT may stimulate the mitochondria to produce more ATP, or it may promote the production of proteins and enzymes that are involved in ATP synthesis. It is also possible that LLLT may stimulate blood flow and oxygenation, which may help to support ATP production. However, more research is needed to fully understand the effects of LLLT on ATP production.

There are varying qualities of LLLT devices on the market. Although more research is needed, there is good evidence for the efficacy of LLLT in hair growth but results depend on the penetration of the light and the strength of the light.
