Low-Level Light Therapy: The Science Behind Laser Caps

Low-level light therapy (LLLT), also known as cold laser therapy, photobiomodulation, low-intensity light therapy, and soft laser therapy, was discovered in the 1960s by a Hungarian physician named Endre Mester. LLLT is a form of therapy that applies low-level lasers or light-emitting diodes (LEDs) to the surface of the body.

Dr. Mester started a series of tests on mice while applying LLLT technology. The mice were shaved, and the tests were intended to detect if the lasers caused cancer in animals. Mester’s conclusions proved that laser therapy did not cause cancer. Instead, it created new hair growth where the mice had been shaved. As this technology developed and more tests were performed, Dr. Mester’s work created a safe and effective method for growing hair on humans.

The scientific principle for LLLT is that light emitted from the lasers stimulates hair growth and reduces hair loss. This process is called photobiomodulation and occurs when laser light is absorbed by the cells and stimulates their metabolism and protein synthesis.

Laser caps are the new trendy high-end device on the market that use low-level light therapy to treat hair loss. But how do these laser cap devices really work?

  • Stimulate Skin Tissue- The lasers emit low light therapy to the skin’s tissue on the scalp. As a result, blood flow is stimulated to the scalp tissue to reduce inflammation and begins to circulate throughout the head. Blood flow circulation transports the essential oxygen and nutrients to the hair follicles and results in cell regeneration in the problematic (thinning) areas of the hair.
  • Cell Absorption and Protein Synthesis - According to Kiierr’s do laser caps work page, low-level laser light energy penetrates the skin, the weakened cells on the scalp absorb the light. This rejuvenates the scalp and allows for new hair to grow.
  • Regenerates Hair Follicle Cells - When the hair follicle cells are regenerated, the hair is “brought back to life” from the dormant (telogen) stage of the hair growth cycle into the healthy growth (anagen) phase.
