Will armpit hair grow back after removal?

Armpit hair is a problem that bothers many people, especially in summer when removing armpit hair becomes a common phenomenon. Along with hair removal, there is another problem that has been bothering everyone, that is, will the armpit hair grow again after removal? Especially, will the armpit hair grow faster as it is removed, like a beard? Now with the continuous development of various technologies, there are many hair removal tools on the market, which are dazzling and even claim that they will not grow again, which is exciting. So, to be precise, will the armpit hair grow again after removal?

First, let’s get to know axillary hair. Axillary hair is the hair that grows under the armpits. Like pubic hair, it is the result of the gonads beginning to secrete estrogen and androgen. Armpit hair appears 1-2 years later than pubic hair. The average age reported abroad is 12-15 years old. Armpit hair is one of the first signs of puberty[1]. Most people have armpit hair, which helps sweat evaporate.

Armpit hair exists in the human body, generally in both men and women. The growth of hair is related to the estrogen and testosterone in the human body, which means that women generally have armpit hair when they reach adulthood. Armpit hair is located under the armpits and is also one of the secondary sexual characteristics of women. Similar to pubic hair, it is the result of the adrenal glands beginning to secrete estrogen and testosterone. Armpit hair appears 1-2 years later than pubic hair, and the average age abroad is 12-15 years old. Chinese women also start to develop armpit hair around the age of 12-15.

Generally speaking, even if you pull out your armpit hair, it will grow again. Armpit hair has a strong regenerative ability and will regrow even after removal. If you pull out the hair by the roots, it means that the hair follicles are damaged, and it will be difficult to grow hair again. This is why plucking armpit hair takes longer to regrow than shaving it. But this does not mean that the hair follicles can be completely destroyed, so there is still a possibility of regrowth.

However, unless you completely destroy the hair follicles when plucking, the hair follicles are the basis for hair growth. Once the hair follicles die and fall off, the hair will not grow again. But general pulling out will not have such an effect, and it is not recommended, as it will lead to more serious consequences. Because the skin under the armpits is thin, tender and sensitive, plucking with tweezers or bare hands, or plucking with wax, is a very painful process. Moreover, if the pulling method is improper, it will cause certain damage to the skin under the armpits, not to mention pulling out the hair follicles by the roots, which will cause great damage to the hair follicles.

Laser hair removal can directly hit the hair roots so that hair will never regenerate. The freezing point hair removal laser can quickly penetrate the epidermis, enter the dermis, and be selectively absorbed by the melanin particles in the hair and hair follicles, producing a photothermal effect. The heat energy in the hair can be conducted to the surrounding area, completely shrinking the hair follicles and hair shafts, and achieving permanent hair removal. The other parts around the hair follicles do not contain melanin particles and therefore do not absorb this light, causing no harm, which is safer and more thorough.
