Ringworm of the scalp (tinea capitis)

Ringworm of the scalp, also called tinea capitis, is caused by a microscopic fungus and not by an actual worm.

Any type of ringworm is easily spread through direct contact with a person, or a pet animal, who has the infection; or through direct contact with the hairbrushes, clothes, towels, bedding, or other items that an infected person has used.

Most susceptible are pre-school and school-age children, and anyone with a weakened immune system.

Symptoms include itchy, scaly, round-appearing patches of hair loss on the scalp.

It is important to see a medical provider for symptoms of scalp ringworm, both to help ease the discomfort and to prevent the spread of the condition to others.

Diagnosis is made through physical examination and sometimes a skin sample for testing.

Treatment involves washing all clothes and bedding in hot water and detergent, and using an antifungal shampoo as well as a prescribed cream or gel for the affected spots on the scalp. Sometimes a course of antifungal tablets will also be prescribed.

Normal episode of itchy skin

Itchy skin is also called pruritis. There are a number of "normal" causes for itching, meaning the cause is not disease-related and does not result in seriously damaged skin.

The most common causes are:

  • Dry skin, due to bathing in soap or bubble bath that may be too harsh and is stripping the natural oils from the skin.
  • Mild allergies, which may be caused by dust; certain plants and flowers; nickel-containing jewelry; and any sort of soap, detergent, lotion, or perfume.
  • Pregnancy, due to stretching of skin or to a condition called prurigo. Prurigo causes small, itchy bumps which may be due to an autoimmune system dysfunction during pregnancy.

Menopause, due to hormonal changes that may leave the skin overly dry.

Diagnosis is made through physical examination and sometimes allergy tests.

Treatment involves bathing only with mild, hypoallergenic soap; regular moisturizing with unscented lotion; wearing soft, loose, non-synthetic clothing; avoiding any substances that seem to provoke the itching; and sometimes prescription medicated creams.

Rarity: Common

Top Symptoms: feeling itchy or tingling all over

Symptoms that always occur with normal episode of itchy skin: feeling itchy or tingling all over

It can occur with or without reddened skin. The exact cause of this condition is not known, although doctors think that some common skin yeast organisms, called Malassezia, may play a role in some people.

Rarity: Common

Top Symptoms: itchy rash, red or pink, rough patch of skin, rash with well-defined border, scalp skin changes, cheek skin changes

Symptoms that never occur with seborrheic dermatitis: fever

Urgency: Phone call or in-person visit
