With the arrival of summer, bare legs have become the way of travel for many women, but some people are shy to show their legs due to excessive leg hair, what should I do? Then you might as well try laser hair removal. Laser hair removal has a clear effect and is more and more sought after by beauty lovers. However, many beauty seekers do not know how to take care of them after treatment, or whether they are suitable for laser hair removal treatment.

Normally, 60%-90% of anagen hairs are removed per treatment. A course of treatment requires about 6 treatments. Most patients achieve satisfactory results after 6 treatments, but refractory cases require multiple treatments.

Generally speaking, the growth period is about 3 years, the regression period is about 3 weeks, and the resting period is about 3 months. Taking leg hair as an example, about 20% of the hair follicles in the adult legs are in the growth phase, about 80% are in the quiescent phase, and less than 1% are in the regression phase.

The principle of laser hair removal is based on selective photothermal action, using melanin as the target chromophore to absorb energy, destroy hair follicles, destroy hair matrix, and organize hair regeneration.

Because only the hair follicles in the growth phase contain melanin, and there is almost no melanin metabolism in the resting phase and the degenerative phase, only the hair in the growing phase absorbs laser energy strongly and is destructive to the hair follicle, while the resting phase and the degenerative phase absorb almost no energy, so The treatment of this part of the hair follicles is only effective when the quiescent hair follicles enter the growing phase, which is why laser hair removal takes multiple times to complete.

Does it affect perspiration?

The human body mainly relies on sweat glands to perspire, but the openings of the eccrine glands are not in the hair follicles. Laser hair removal only destroys hair follicles, so it will not damage the sweat glands and will not affect normal perspiration.

Many people mistakenly believe that after laser hair removal, the part will not grow hair for life, and this persistence is not permanent in the true sense. In general, the overall hair removal rate can reach 90% after multiple laser treatments. Of course, its efficacy is affected by many factors. Even if there is hair regeneration, it is very soft and does not affect the elegance.

Because hair grows in cycles, it is divided into growth phase, regression phase, and rest phase. When one part is dormant, the other part is falling off, and the other part is growing, and the laser can only act on the hair that belongs to the growth phase. When the rest phase grows out and becomes the growth phase, do it again, so it is necessary to cycle Multiple treatments are required to achieve near-continuous hair removal results.

Does hair removal hurt?

During laser hair removal treatment, there will be a feeling of ant biting, which is completely tolerable
