Laser hair removal using light technology is an effective way to reduce hair growth. In this method, laser light is radiated into the skin and selectively gets absorbed by the melanin in the hair. The absorbed light energy is converted into heat and destroys the hair follicle. With repeated laser sessions, the hair follicles are permanently damaged and hair growth is significantly reduced. Simply put, laser hair removal destroys hair follicles and prevents them from growing back by targeting hair pigments and converting light energy into heat.
Laser Hair Removal Function
In the process of laser hair removal, the skin acts like a filter. Laser light, with a certain wavelength, penetrates deep into the skin and is absorbed by the melanin in the hair. Melanin is the pigment that gives color to the hair and acts as a powerful absorbent for laser energy. When the laser energy is absorbed by melanin, it is converted into heat and transported to the hair follicle. This heat causes severe damage to the hair follicle and ultimately its destruction.
Destruction of the hair follicle prevents hair from growing back. Of course, it should be noted that in order to remove all the unwanted hair permanently, several sessions of laser treatment are required. Because not all hair is in the same growth phase, and laser is only effective on hair that is active in the growth phase. By repeating the laser sessions, you will gradually get rid of all the unwanted hair and you will have smooth, hairless skin.
One of the main benefits of laser hair removal is its long-lasting and even permanent results. With the destruction of the hair follicle, hair regrowth is significantly reduced, and in many cases, the hair is completely destroyed. In addition, laser hair removal is a quick and effective way to remove unwanted hair on different areas of the body. This method is less painful than traditional methods such as waxing and threading and takes less time. Also, laser hair removal can be used for different skin and hair types, and its side effects are very low.
Due to the mentioned benefits, laser hair removal has become one of the most popular hair removal methods. Many people turn to this method to have smooth and hairless skin.

Conclusion
As a result, laser hair removal works by targeting the melanin in the hair follicle. The laser light penetrates the skin and is absorbed by melanin, which is then converted into heat and destroys the hair follicle. However, hair growth is cyclical, and the laser only works on hair that is active in the growth phase. For this reason, several sessions of laser therapy are required to achieve the desired results. Each laser session removes a number of hair follicles, and with repeated sessions, hair growth in the target area gradually stops.
