Hair belongs to the appendage of human skin. The part of hair buried in the skin is called hair root, and the part exposed outside the skin is called hair trunk. The lower end of hair root expands into a ball in the dermis, and contains rich blood vessels, nerves, and cells with strong proliferation and differentiation ability, which are collectively called hair papilla. It can be said that hair papilla is the foundation of hair growth and development. If a hair loses its nipples, it will lose all its nutrition supply. After it dries up and falls off, it can no longer grow new hair. On the contrary, if a hair breaks from the hair shaft or even the hair root, but the hair nipple is not damaged, new hair can still grow even if the hair falls off. Therefore, when hair removal is used, only by completely destroying the dermal papilla can permanent hair removal be achieved. Otherwise, it will only damage the hair shaft, but under the nutrition of the hair nipples, new hair will grow.
Shaver depilation
In traditional hair removal, the most efficient and painless way is to remove hair with a razor. But shaving with a razor is not an easy job.
Correct method: The razor blade should be perpendicular to the skin at a 90 degree angle, and then move forward along the direction of hair growth, so that the pores will not be scratched and the skin will not become red. And remember to shave every day so that no stubble will grow!
Hair removal cream
Hair removal cream uses chemical substances to dissolve hair. Frequent use of hair removal cream can easily lead to skin redness, swelling and sensitivity, especially in physiological period.
Beeswax depilation
Honey wax hair removal is a tear type hair removal method. The hair is easy to break in part of the pores, and the broken hair is extremely easy to penetrate into the hair follicle, causing folliculitis.
Laser hair removal
The essence of laser hair removal is to use the photothermal effect to make the hair follicle produce high temperature, change the hair follicle structure, and permanently remove hair. Although laser hair removal can be done once and for all, it is expensive and may lead to uneven skin color and even scars.
Shaving, waxing and laser hair removal can be used. Shaving and waxing are temporary hair removal methods, which can only last for 1-2 months. Laser hair removal can be regarded as permanent hair removal, because it can make the cell protein of hair papilla coagulate and denature under the action of laser beam, lose its biological activity, and achieve complete hair removal.
