The majority of women grow pubic hair after puberty, and the appearance of pubic hair is curly. Due to individual differences, the thickness of pubic hair varies, which is normal. Some women do not have pubic hair after puberty and still do not have pubic hair after adulthood, mainly because the hair follicles in the pubic area are not sensitive to androgens, so they do not grow pubic hair. The amount of pubic hair and the lack of pubic hair have no effect on the sexual function and fertility of women, so women who do not have pubic hair do not need to worry. The physiological function of pubic hair is to play the role of warmth, blocking the friction between the vulva and clothes, if there has been no pubic hair, it has been insensitive to friction, so do not worry.
