Laser hair removal uses beams of highly concentrated light designed to selectively penetrate into the hair follicles, to be absorbed by the pigment in the hair follicles and to destroy the hair within that hair follicle. In fact Melanin is the pigment that gives hair its color. The melanin must be able to absorb the energy that is produced by the laser for an effective hair removal process with a considerable amount of heat. The melanin surrounds the structure that is responsible for germinating hair inside the hair follicle. In fact this structure is no longer protected once the absorbed laser energy destroys the melanin. If there will be excessive amount of heat that is applied will damage the hair germination structure.

For laser hair removal to be effective skin absorption must be kept at a minimum. By applying a cold compress to the affected area which is an important factor in restraining the skin's absorption of laser energy to keep the skin cool during the laser hair removal process. Then only this will allow the laser to avoid the colder skin to reach the melanin within the hair follicle. That is another way of keeping the skin cool is to use the latest 'multi pulsing' laser technology with pulsed laser energy or interrupted, rather than streamed. Due to this pulsing, less heat is applied instantly to cool and at the same time, protect the skin. There are varieties of lasers and light sources have been developed that may be engaged in laser hair removal. Various types of lasers are utilized with laser hair removal and these are includes alexandrite, a long pulse laser; Diode, only used for darker skin and Neodymium YAG which is very much effective for both deep and near-surface follicles of the hair and lastly an intense pulsed light sources- Ruby consists of red laser beams capable of targeting melanin.

However it is mostly important to consider about your financial ability if you are going for a hair removal procedure. In fact many people also assume that a person need only be financially capable of paying for the multiple treatments that are necessary. Typically, laser hair removal sessions cost approximately $500 each.

Even you need to consider about your pigment. Pigment is what gives color to skin and also to hair. The color of a person's hair must be darker than the skin that surrounds it to be effective as a hair removal process. That is why people with dark, coarse body hair and light skin have more success than light- or red-haired individuals or individuals with dark or tanned skin.
