Can laser hair removal remove hair permanently? Does laser hair removal cause any harm to the body?

I heard that laser hair removal can achieve the purpose of permanent hair removal. So is laser hair removal really effective? Is laser hair removal harmful to the body?

Laser hair removal is a non-invasive hair removal technology that mainly uses selective photothermal effects. The laser penetrates the skin and reaches the hair follicles. The light energy is absorbed by the melanin in the hair follicles. The light energy is converted into heat energy, destroying the hair follicle tissue, and the hair is gradually removed. The laser hair removal device has adjustable pulse width, energy and irradiation time, and can remove hair of different thicknesses. Laser hair removal is not permanent, it just destroys the hair follicles and stops the hair from growing. Or you can stretch the hair growth cycle as much as possible, which is basically almost impossible to grow, but you have to do it several times in a row to achieve a more ideal hair removal effect.

Laser hair removal is harmless to the body. The principle of laser hair removal is the selective photothermal effect of laser. Hair follicles contain melanin. During laser treatment, hair follicles absorb light, which is converted into heat. Heat destroys hair follicles and achieves the effect of hair removal. Laser hair removal is relatively safe and permanent. It can remove 90% of thick hair. Laser hair removal needs to be treated according to the hair growth cycle, and generally requires 3-8 times. Laser hair removal only destroys hair follicles, but not the surrounding sweat glands, so it will not cause abnormal sweat secretion.

Laser hair removal will not cause more and more hair. Laser hair removal is achieved by destroying the hair follicle tissue. After about one course of treatment, that is, three to four laser hair removal treatments, it can be thoroughly cleaned and will not grow again. During this period, it is recommended not to eat spicy and irritating foods, and take protective measures when going out. The laser part should not be exposed to the sun.
