Pubic hair

Pubic hair is coarse terminal hair that grows in the pubic region, typically developing during puberty under the influence of sex hormones.

Puberty: Puberty is the developmental transition in which hormonal changes produce sexual maturation and reproductive capability. Pubic hair is one visible sign of this broader developmental transition.
Hair shaft: The hair shaft is the visible, keratinized portion of a hair extending beyond the skin. The visible pubic hair is the exposed shaft produced by its follicle.
Pubic hair removal: Pubic hair removal is the deliberate reduction or elimination of hair in the pubic region. It is a common grooming practice with methods ranging from shaving to laser treatment.
Body hair: Body hair is hair that grows on the human body outside the scalp. Pubic hair is one region-specific form of human body hair.
Androgens: Androgens are hormones that promote traits associated with male sexual development and also act in people of every sex. Androgen signaling helps trigger terminal-hair growth in the pubic region.
Keratin: Keratin is a family of structural proteins that forms hair, nails, and the outer skin layer. Pubic-hair shafts consist largely of keratinized cells.
Pseudofolliculitis pubis: Pseudofolliculitis pubis is inflammation caused by shaved hairs growing back into or beneath skin in the pubic area. Close grooming can make curved pubic hairs produce painful ingrown-hair lesions.
Body image: Body image is a person's perceptions, thoughts, and feelings about their own body. Expectations about pubic hair can influence comfort and body image.
Hair follicle: A hair follicle is a skin structure that produces and anchors a hair shaft. Pubic hair grows from follicles whose response to hormones changes during puberty.
Sebaceous gland: A sebaceous gland is a skin gland that releases oily sebum, usually into a hair follicle. These glands commonly empty into follicles in the pubic region.
