Symptoms

By Mayo Clinic staff

Ingrown hairs most commonly appear in males in the beard area, including the chin, cheeks and, especially, the neck. They can appear on the scalp in males who shave their heads. In females, the most common areas for ingrown hairs are the armpits, pubic area and legs. Signs and symptoms include:

  • Small, solid, rounded bumps (papules)
  • Small, pus-filled, blister-like lesions (pustules)
  • Skin darkening (hyperpigmentation)
  • Pain
  • Itching
  • Embedded hairs

When to see a doctor
An occasional ingrown hair isn't cause for alarm. See your doctor if:

  • Ingrown hairs are a chronic condition. Your doctor can help you manage the condition.
  • You're a woman with ingrown hairs as a result of excessive unwanted hair growth (hirsutism). Your doctor can determine whether your excess hair is a result of treatable hormonal abnormalities, such as polycystic ovary syndrome.
