The principle of laser hair removal revolves around the principle of light radiation. The concept of laser hair removal is simple to understand.

Laser Hair Removal involves the use of light energy for the removal of hair. The basic principle of laser hair removal is that the dark objects absorb light. The laser will selectively target hair or the hair root and burn it.

This is possible only when the target area is darker than the surrounding skin. The dark target area is called chromophore and it can be created artificially or is found naturally on the skin.

Natural chromophores are melanin and hemoglobin. Melanin is a pigment that gives color to the hair. Hemoglobin is what gives red color to the blood. Carbon is an artificial chromophore.

Carbon is introduced into the skin by rubbing a carbon- based lotion into the skin after waxing. The principle of laser hair removal is selective photothermolysis. The laser hair removal treatment is also called phototricholysis or photoepilation.

There are certain technical parameters that determine the effectiveness of the laser hair removal process.

* Pulse widths - Studies have established that longer pulse widths are more effective for laser hair removal process and have fewer side effects.

* Width of the laser beam - The width of the laser beam determines the efficacy of laser hair removal process. The width of the laser beam should be four times as wide as the depth of the target.

* Repetition - Repetitions of the laser hair removal process is necessary for lasting solutions against the problem of laser hair removal. Usually two or three pulses of light have to be targeted for efficient removal of hair.

Cooling is a necessary ingredient of laser hair removal process. Cooling of the skin is done along with the laser treatment in order to prevent pain and reduce the side effects of the hair removal process.

Use of clear gel, contact cooling, cryogen spray and air- cooling are the various types of cooling methods for laser hair removal. The color of the hair is an important factor in the principle of laser hair removal.

Laser works effectively only on relatively dark hair, that is present among lighter surroundings. This is because light energy is absorbed only by the darker area, making selective absorption of the light energy efficient. This removes the hair without affecting the nearby skin. =========================================================== Find out all you need to know about permanent laser hair removal.
