We have pubic hair because it actually does a few useful jobs for the body, mainly protection, friction control, and helping manage the micro‑environment around the genitals.

Quick Scoop

Pubic hair grows in puberty as part of sexual maturation and is found in all sexes, even though patterns and thickness vary from person to person. Biologists think it stuck around in humans because it offers several small advantages rather than being purely cosmetic.

Main reasons we have pubes

  • Friction protection : The skin around the genitals is thin and sensitive, and hair acts like a soft buffer during walking, exercise, and sex, reducing chafing and irritation. Some researchers even describe pubic hair as a kind of “dry lubricant” because hair rubbing on hair is less harsh than skin on skin.
  • Barrier against germs: Like eyelashes and nose hair, pubic hair can trap dirt, debris, and microorganisms, and the follicles produce oils (sebum) that make it harder for some bacteria to multiply. This may slightly lower the risk of certain infections by keeping some pathogens from directly reaching the skin or mucosa.
  • Temperature and moisture: Hair helps maintain a more stable temperature and moisture level around the genitals, which can support the local microbiome and comfort. This “micro‑climate” effect might be one reason pubic hair concentrated in that area as humans lost most other body hair.
  • Signals and scent: Pubic hair appears at puberty and may act as a visual sign of sexual maturity, and it can hold on to body scents and pheromones that play a role in sexual attraction in some theories. This is not the main purpose for everyone, but it is one evolutionary hypothesis for why we have it.

Do you need to keep it?

  • From a health perspective, having pubic hair is normal, and so is trimming, shaping, or removing it; the key is gentle technique and good hygiene to avoid cuts, irritation, and ingrown hairs.
  • Removing pubic hair slightly reduces its protective roles (against friction and as a germ filter), but many people manage this safely with careful grooming and regular washing.

Bottom line: we have pubes because they help cushion delicate skin, filter some germs, and shape the tiny environment around our genitals, even though modern grooming habits are all about personal preference.
