Will laser lip hair removal cause rebound?

Many female friends feel that they have a lot of hair on their lips, which not only makes their skin look darker, but also makes them feel very masculine and unladylike. Due to the popularity of laser hair removal, many people choose to use laser to remove lip hair. Although it is said that laser hair removal is permanent, some people find that the hair will grow back after removal, just like weight loss rebound. So will laser lip hair removal cause rebound?

Laser lip hair removal will cause rebound. Of course, everyone has individual differences, which is related to the body's own hormones. After laser lip hair removal, small hairs will grow again. Generally, it takes 45 days to a year for the small hairs to grow again. For some people, it may take longer or shorter time for the hairs to grow again. This is mainly related to the fact that the laser lip hair removal device does not completely remove the lip hair, and that the person undergoing hair removal has vigorous secretion of male hormones and vigorous hair growth in the body. However, the lip hair that grows back after freezing point lip hair removal is generally thinner and lighter in color, making it difficult to detect.

It usually takes 3-7 sessions of laser hair removal to completely remove lip hair. This is because hair goes through three stages: growth phase, resting phase, and shedding phase. Laser acts on melanin, which only exists in growth phase hair follicles. Therefore, laser mainly destroys growth phase hair follicles. There is less melanin in the hair follicles during the shedding phase, and no melanin in the hair follicles during the resting phase. Lip hair removal treatment has little effect on removing lip hair during these two periods, so lip hair removal generally needs to be done several times.

The best interval between each laser lip hair removal treatment is 30 to 45 days, because it usually takes 30-45 days for hair follicles to go from the regression phase to the growth phase. That is to say, after a lip hair removal treatment, the lip hair in the growing period will fall off, but in 30-45 days the hair will enter the growing period from the resting period, and very short and light small hairs will appear on the lips. At this time, those who love beauty need to undergo lip hair removal treatment again.

Laser lip hair removal removes lip hair in the growth stage, and in theory it will not recur. However, because the lip hair growth cycle is divided into three stages, and laser lip hair removal is only effective for lip hair in the growth stage, some hair will grow after a single laser lip hair removal treatment, but this is not a recurrence.
