Ingrown Hairs
When a hair begins to grow back after being removed, it might become ingrown if it grows in a direction that bends into the skin. It is a common side effect of hair removal methods, including shaving, tweezing, and waxing.
Ingrown hairs are influenced by the structure of the hair and the direction in which the hair is growing. After a haircut, the hair that grows back from a curved follicle is more likely to reenter the skin because of the tight curl it forms. Hair that has been shaved has a sharper edge, making it simpler to puncture the skin.
Ingrown hairs mostly appear in the pubic region (bikini line and inner thigh), legs, armpits, and the beard region of the face (neck, cheeks, and chin). However, they are not limited to those areas and can appear everywhere on the body, including the face, chest, back, belly, nostrils, eyebrows, and buttocks.
An infected ingrown hair occurs when hair that has grown out and coiled back into the skin does not exit the skin properly. Frequent recurrences are occasionally described as folliculitis.
