The good thing about laser hair removal treatment is that you get rid of the excess hair in your body with minimum discomforts. The treatment usually does not take long and it does not require the patient to stay in the hospital for the treatment. Furthermore, for most people, the hair do not really come back after the laser hair removal treatment.

There are at least four types of laser lights that doctors commonly use in laser hair removal treatment. The Alexandrite, the ruby, the diode and the ND and LP ND Yag or the Candela Gentle Yag are considered as the safest when it comes to laser hair removal.

How Does Laser Hair Removal Work?

Technically, laser hair removal treatment works by sending out laser light to the hair follicles and destroying the roots of the hair. Dermatologists use just enough amount of laser light to destroy the hair follicles without really harming the surrounding tissues. Once the roots of the hair are destroyed, the hair usually does not grow again. In some cases, the hair does grow back again but the grain of the hair is now finer and would not really look as ugly as it used to be.

How Does the Laser Beam Find the Hair Follicles?

In finding the hair follicles, the dermatologists usually focus on the dark color of the hair to guide them. Consequently, the laser beam is targeted on the dark colored portions in the skin of the patient. Since laser hair removal treatment relies on the difference between the colors of the skin and the hair of the person, not all persons would qualify for this type of hair removal treatment.

People who have very light colored skin and those with very dark colored skin are usually not qualified for this type of treatment. According to dermatologists, very fair people usually have very fair hair that it is very difficult for them to distinguish the skin from the hair follicles.

For very dark people, the problem of identifying the hair form the skin is even more difficult. Since it is dangerous to just point the laser beam to non-specific directions in the skin, most dermatologists would rather not perform laser hair removal treatment on very fair and very dark types of skin.
