1. What is hair removal?

Hair removal is a medical procedure that removes unwanted body hair using a focused beam of light (a laser) or hair removal devices. Traditional hair removal methods such as razors, waxing, hair removal creams.. and modern hair removal methods like lasers all have their pros and cons. However, nowadays most people learn and implement laser hair removal methods.

During laser hair removal, the laser emits light that is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which damages the tubular sacs in the skin (hair follicles) that produce hairs. This damage inhibits or slows hair growth in the long term. Accordingly, you can treat unwanted hair in almost any area, except for the eyelids or the surrounding area. However, tattooed skin should not undergo hair removal.

Hair color and skin type affect the success of laser hair removal. The basic principle is that the pigment of the hair, not the pigment of the skin, will absorb the light. The laser will affect the hair follicles, not the skin.

The risk of skin damage is greater when there is less contrast between coat and skin color. But advances in laser technology have made laser hair removal an option for people with darker skin. Laser hair removal is less effective on hair colors that do not absorb light well: yellow and white.

Although laser hair removal effectively delays hair growth in the long run, it usually does not provide permanent hair removal. You need multiple laser hair removal treatments for initial hair removal and may also need maintenance treatments. Effective laser hair removal can be done on everyone, especially those with light skin and dark hair.
