Causes Of Fungal Infection – Scalp

Fungi are germs that can live on the dead tissue of the hair, nails, and outer skin layers. Ringworm of the scalp is caused by mold-like fungi called dermatophytes.

The fungi grow well in warm, moist areas. A tinea infection is more likely if you:

  • Have minor skin or scalp injuries

  • Do not bathe or wash your hair often

  • Have wet skin for a long time (such as from sweating)

  • Ringworm can spread easily. It most often affects children and goes away at puberty. However, it can occur at any age.

You can catch ringworm if you come into direct contact with an area of ringworm on someone else’s body. You can also get it if you touch items such as combs, hats, or clothing that have been used by someone with ringworm. The infection can also be spread by pets, particularly cats.

Symptoms Of Fungal Infection – Scalp

Ringworm may involve part or all of the scalp. The affected areas:

  • Are bald with small black dots, due to hair that has broken off

  • Have round, scaly areas of skin that are red or swollen (inflamed)

  • Have pus-filled sores called kerions

  • May be very itchy

  • You may have a low-grade fever of around 100°F to 101°F (37.8°C to 38.3°C) or swollen lymph nodes in the neck.

  • Ringworm may cause permanent hair loss and lasting scars.

Exams & Tests

Your health care provider will look at your scalp for signs of ringworm.

You may also need the following tests:

  • Examination of a skin scraping from the rash under a microscope using a special test

  • Skin culture for fungus

  • Skin biopsy (rarely needed)

Treatment Of Fungal Infection – Scalp

Your provider will prescribe medicine you take by mouth to treat ringworm on the scalp. You will need to take the medicine for 4 to 8 weeks.

Steps you can do at home include:

  • Keeping your scalp clean.

  • Washing with a medicated shampoo, such as one that contains ketoconazole or selenium sulfide. Shampooing may slow or stop the spread of infection, but it does not get rid of ringworm.

  • Other family members and pets should be examined and treated, if necessary.

  • Other children in the home may want to use the shampoo 2 to 3 times a week for about 6 weeks.

  • Adults only need to wash with the shampoo if they have signs of tinea capitis or ringworm.

Once the shampoo has been started:

  • Wash towels in hot, soapy water and dry them using the hottest heat as recommended on the care label. This should be done each time the towels are used by someone who is infected.

  • Soak combs and brushes for 1 hour a day in a mixture of 1 part bleach to 10 parts water. Do this for 3 days in a row.

  • No one in the home should share combs, hairbrushes, hats, towels, pillowcases, or helmets with other people.
