The hair that is visible on the head is actually dead and is made of keratin. Follicles keep on generating new hair and it pushes the older ones as it grows.

Sometimes these hair follicles become smaller and become dormant. This prevents growth of further hair resulting in hair loss or baldness.

How does laser light therapy for hair loss work?

Hair growth cycle comprises of three distinct phases Growth or the anagen phase Resting or telogen phase, and Shedding or catagen phase

Hair loss results because of dihydrotestosterone (DHT), a testosterone compound of the skin. Laser therapy works by increasing the blood flow in the scalp region which stimulates metabolism in catagen and telogen follicles. This leads to production of anagen hair.

The photons emitted from diodes react on the cytochrome C oxidase leading to production of adenosine triphosphate (ATP), an organic chemical responsible for providing energy to the cells.

These ATP are converted to cyclic Adenosine Monophosphate (AMP) in the hair follicle cells. It releases energy and helps in the metabolic process of hair growth.

The laser light therapy prevents excessive build-up of DHT which ultimately prevents hair loss and cures partial baldness.
