When it comes to thick hair, many people are more disgusted, but in fact, hair is not useless. For example, the perspiration of the human body and the beautiful hairstyle are all the credits of the hair. In summer, when many people want to show their beautiful body, they are affected by too much hair on their bodies. Therefore, at this time, many people choose laser hair removal to enhance their personal confidence. So, what about laser hair removal methods?

Laser hair removal is a safe and fast hair removal technology. It is based on the principle of selective photothermodynamics. By reasonably adjusting the pulse width of the laser wavelength energy, the laser passes through the skin surface and reaches the hair follicles at the root of the hair. The light energy is absorbed and converted into damaged hair follicles. The thermal energy of the tissue, so that the hair loses its ability to regenerate without damaging the surrounding tissue.

Laser hair removal is less painful, can act on deep hair follicles in different parts, and remove hair completely. The laser can selectively act on the skin tissue without damaging the normal epidermis and tissue. The treatment time is short and does not affect normal work and life.

Laser hair removal is based on the principle of selective photothermodynamics. By reasonably adjusting the pulse width of the laser wavelength energy, the laser can pass through the skin surface and reach the hair follicle at the root of the hair. The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thereby making A technique in which the hair loses its ability to regenerate and may damage surrounding tissue and is mildly tingling. Laser hair removal is a safe, fast and long-lasting hair removal technique. Laser hair removal is suitable for almost all people, and the scope of application is also very wide.

Avoid taking a hot bath one day after surgery; pay attention to UV sun protection after surgery.

For permanent hair removal, the hair follicles must be destroyed. The heat of the laser is transmitted to the deep part through the hair shaft. On the one hand, the wavelength of the laser needs to be in the spectral range that the hair can absorb; on the other hand, the wavelength of the laser needs to be long enough to penetrate into the deep part of the dermis. Therefore, there are many types of lasers for hair removal, but they all have the above two elements, which is why hair removal is better for black hair and less effective for blond and white hair.

There are also pigments in the epidermis, which can absorb light waves like hair follicles, so hair removal has the risk of injuring the epidermis, especially for patients with dark skin, so patients with fair skin have a great advantage. Light waves need to pass through the epidermis and then to the dermis, so epidermal cooling can improve the safety of hair removal and reduce the pain of hair removal. Both the gem bald head for freezing point hair removal and the cold gel used for hair removal have this effect. The difference between laser hair removal and photon hair removal is that lasers are relatively more stable and safer, and the hair removal efficiency is higher and more comfortable. There are a lot of semiconductor freezing point hair removal on the market now, making hair removal more popular.

Although hair removal is related to the wavelength and performance of the equipment, it also has a great relationship with the operator's operation. The operator must give energy patiently, and must carefully observe the hair response of the skin, in order to get it just right, destroy the hair follicle without harming the skin. Many patients may be afraid of pain, or the operator may be afraid of injuring the patient's skin, or the operator is not patient and careful, so that the energy for hair removal is not enough. If the energy absorbed by the hair is not enough, the hair will develop photoresistance and affect the next treatment, and ultimately affect the effect of permanent hair removal.
