Hair growth near the anus is normal. The appearance of secondary human sexual characteristics leads to the growth of beard, armpit hair, hair in the perineal area, and hair around the anus. The thickness of the hair is related to genetics as well as individual and ethnic differences. Secondary sexual characteristics can also lead to hyperpigmentation of the skin around the perineum and anus, resulting in a darker color of the anal skin than other areas, which is also normal. If the hair around the anus is more vigorous, you should pay attention to the cleanliness of the area around the anus to avoid the accumulation of bacteria and infectious substances that can lead to perianal diseases. You should also pay attention to a light diet and keep your stools soft and clear. Do not cut the hair around the anus by yourself, because the root of the hair is relatively hard, which can cause local skin damage around the anus during the activity, and even produce perianal inflammation.
