Overview

Causes

Tinea capitis is caused by a fungus that invades the hair shafts. It is spread by:

  • Person to person contact
  • Contact with the fungus on:
    • Fallen hair
    • Combs, hats, and bedding
  • Contact with pets that have the fungus

Risk Factors

Tinea capitis is more common in children 3 to 7 years of age. Other things that may raise the risk are:

  • Sharing combs, brushes, or hats
  • A weak immune system, such as with:
    • HIV
    • Certain long term diseases such as diabetes or cancer
  • Crowded living conditions
  • A large family size

SymptomsandDiagnosis

Symptoms

Tinea capitis may cause:

  • Itching of the scalp (not always present)
  • Bald patches
  • Scales, sores, or black dots on the scalp

Diagnosis

The doctor will ask about symptoms and past health. A physical exam will be done. It will focus on the scalp. This is often enough to make the diagnosis.

If the diagnosis is not clear, the doctor may scrape the scalp or clip a few hairs to look for signs of infection.

Treatments

Treatment

Antifungal medicine will be given to kill the infection. It may be taken by mouth or used as a cream or shampoo. This can also help lower the chances that the infection will spread to others.

Prevention

The risk of tinea capitis can be lowered by not sharing combs, brushes, or headgear.
