Scalp Problems - Topic Overview

(continued)

Painful sores, blisters, or bumps that develop on the scalp may be caused by:

  • Infection of the hair shafts (folliculitis) or the skin (such as impetigo).
  • An allergic skin reaction (contact dermatitis).
  • Viral infections, such as chickenpox and shingles.
  • A skin condition, such as acne.
  • A cyst, such as an epidermal or sebaceous cyst, a sac beneath the outer layer of the skin that is filled with a greasy white material. These cysts most often appear on the scalp, ears, face, back, or scrotum and are caused by plugged ducts at the site of a hair shaft. Other problems can develop if the cyst becomes infected.

Skin cancer can occur on the scalp, particularly in areas not well-covered by hair. It can destroy skin cells and tissues and, in some cases, spread (metastasize) to other parts of the body. Skin cancer may appear as a growth or mole, a change in a growth or mole, a sore that does not heal, or irritation of the skin. The three most common types of skin cancer are basal cell skin cancer, squamous cell skin cancer, and melanoma.

The treatment for scalp problems depends on what is causing the problem.

Check your symptoms to decide if and when you should see a doctor.
