Tinea capitis is caused by a fungus. The fungus invades 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
Tinea capitis may cause:
- Itching of the scalp (not always present)
- Bald patches
- Scales, sores, or black dots on the scalp
The doctor will ask about symptoms and health history. A physical exam will be done. The person may be referred to a skin doctor.
Diagnosis is often based on a scalp exam. If the diagnosis is uncertain, the doctor may scrape the scalp or clip a few hairs for testing.
Tests on the sample may include:
- Microscopic exam
- Fungal culture
The goal is to clear the infection. The main treatment for tinea capitis is antifungal medicine taken by mouth. Antifungal creams may also be added. Antifungal shampoos may help reduce the spread to others.
The condition can be difficult to treat.
