Phototherapy is a centuries-old therapeutic concept. But little is known about its wonders as a hair treatment for hair loss. This is because only a few completely understand the concepts of photobiology.

Phototherapy is the application of light from any source (be it natural or artificial) to serve a therapeutic purpose. The specific light sources commonly used in treating hair loss are low level laser and light emitting diodes.

Low level laser is a coherent light which yields several benefits t0 the living cells. LLL causes photo-biostimulation, a natural process comparable to photosynthesis. During photo-biostimulation, light energy becomes cellular energy. With increased cellular energy, the cell becomes more productive.

Low level laser therapy does not put anyone at any significant risk. It has been approved by the Food and Drug Administration to be a safe and effective hair treatment for hair loss for both men and women.

For the past several years, saw palmetto has been the subject of numerous studies about prostate health. Saw palmetto is believed to block dihydrotestosterone (DHT) build-up through a liposerolic extract which is anti-androgen. When taken as a drug, it kills the androgen receptors found in the hair follicles. Specifically, it blocks type 1 and type 2 forms of 5α reductase. People that are deficient of L-Lysine, an essential amino acid, would most likely benefit from saw palmetto. Saw palmetto is a natural hair treatment for hair loss which is an active ingredient in some oral and topical drugs for hair loss.
