Next, let's follow the editor of the beauty instrument manufacturer to learn about the things you must know about laser hair removal!

The growth of hair has growth phase, catagen phase and resting phase. The hair matrix cells divide rapidly in the growth period, and the melanin is the most in this period, so it is extremely sensitive to the laser; in the degenerative period, the hair matrix degenerates, and the hair papilla shrinks; in the telogen phase, the hair follicles are separated from the dermal papilla, and the hair falls off, and the time of the telogen period varies with the location . For example, 30% of the beards are in the resting phase, and 70% are in the growing phase. The resting phase lasts for about 2-3 months. The density of hair follicles is about 500/cm2, and the depth of hair follicles is about 2.0-4.0mm.

2. The relationship between the hair growth cycle and the time and frequency of hair removal

(1) Because the laser has no obvious effect on the hair in the catagen and telogen phases, the laser can only work after these hairs enter the growth phase, so laser hair removal requires multiple treatments before the effect is obvious.

(2) If the proportion of hair in a certain part is in the anagen period is small, the number of treatments should be increased. On the contrary, the number of treatments can be reduced.

(3) Based on the fact that different parts of the hair have different growth cycles, the interval between each treatment is also different. For example, the hair on the head has a relatively short quiescent period, so the interval can be as short as 1 month; the quiescent period of the hair on the trunk and limbs is relatively long, so the treatment interval should be about 2 months.

(4) The depth of the hair follicles also varies from site to site. If the depth is deeper, laser treatment with a longer wavelength should be used. On the contrary, if the depth is shallower, laser treatment with a shorter wavelength can be used.

(5) If the density of hair follicles in a certain part is too high, the laser energy should be appropriately reduced during treatment.quantity.
