What is Ingrown Hairs?
Ingrown hairs happen when a hair curls back or grows sideways into the skin instead of growing outward, causing a small, sometimes itchy or painful bump, often after shaving, waxing, or plucking. They're especially common in areas with coarse or curly hair, such as the face, neck, and bikini area.
Most ingrown hairs resolve on their own within a few days to weeks, though good hair removal technique and gentle skincare can help prevent them from developing frequently.

Clinical context
Hair removal technique matters more than the method itself
Whatever hair removal method you use, technique makes a significant difference to ingrown hair risk — shaving in the direction of hair growth, using a sharp blade, and avoiding pulling the skin too tight can all help reduce their occurrence.

Practical steps
Avoid Picking or Digging at Ingrown Hairs
Picking or trying to dig out an ingrown hair with unclean tools can introduce infection and cause scarring — gentle exfoliation is a safer approach to help release trapped hairs.
- 1Exfoliate gently before hair removal.This helps remove dead skin cells that can trap hairs, reducing the chance of them becoming ingrown.
- 2Shave in the direction of hair growth.This reduces irritation and the chance of hair curling back into the skin.
- 3Use a sharp, clean razor or appropriate hair removal tool.A dull blade increases irritation and ingrown hair risk.
- 4Moisturize the area after hair removal.This supports healthy skin and can reduce irritation.
- 5Consider alternative hair removal methods if ingrown hairs are frequent.Some methods cause fewer ingrown hairs for certain people and hair types.
