HOW LASER HAIR TREATMENT WORKS?

Principle of laser hair therapy (LLT)

Hair growth progress experiment results using laser hair therapy

 

Have you noticed that during the summer months when we are exposed to extended hours of natural sunlight our hair grows faster and thicker? It is the pure red spectrum of sunlight that stimulates blood supply to our scalp and provokes this biological phenomenon. Science has now harnessed this energy providing mankind with a therapeutic solution to hair loss in the form of laser hair therapy.

 

To understand the mechanism responsible for the results achieved with laser hair therapy, it is necessary to understand the difference between high level and low level laser light (LLLL) energy.

 

White light produced by the sun and commercial light bulbs is comprised of all colors of the light spectrum and emits its light in all directions. Normal light with a high degree of infrared light produces a thermal effect on the skin. This is due to its high energy and the high absorption rate of water in the surface of the skin.

 

Laser light has one color and produces a coordinated emission of photons traveling in a parallel path, capable of projecting its highly concentrated energy on a small determined area regardless of the distance

High energy lasers heat the water in the outer cell structure of the skin and are thus effective medical instruments for creating surgical incisions, skin resurfacing and hair removal.

Pulsed laser is sequenced to provide intermittent cooling of the skin's surface and alleviate burning.

Low level lasers or cold lasers have no thermal component and cannot cut, burn or vaporize tissue. They operate on the principle of photo-bio-therapy. This is due to the permeability of the epidermis for the specific colors (visible red and near invisible infrared). When LLLL is absorbed by cellular structures, a photo-biochemical chain reaction is triggered, provoking positive, therapeutic results.
