Tinea capitis commonly presents with numerous symptoms, such as an abundance of dandruff, itchy scalp, formation of crusty pustules, and scaling. There are four types of tinea capitis, each differing slightly in symptoms. For example, yellow tinea can lead to atrophic scarring and permanent hair loss; white tinea typically causes brittleness of hair, eczematous or herpetic lesions; black tinea often leaves behind follicular damage and scarring; finally, pustular tinea can lead to secondary bacterial infections with exudation and lesion formation.

How can tinea capitis be treated to eradicate it completely?

To achieve a radical cure for tinea capitis, it is first necessary to consider the extent of the condition. If the affected area is not very large, then topical medications may suffice. Common choices for antifungal topical medications include Terbinafine Hydrochloride Cream, Luliconazole Cream, Oxiconazole Nitrate Cream, or Ketoconazole Cream. If the tinea capitis is progressing and there is significant damage to the hair in the affected area, oral medication may be required for treatment. However, liver and kidney function tests should be conducted prior to this. If liver and kidney functions are normal, options include oral Itraconazole Dispersible Tablets, Terbinafine Hydrochloride Tablets, or Fluconazole Capsules. If the local hair condition is severe, it may be necessary to timely shave the head while ensuring cleanliness and hygiene of the scalp during treatment.

What is the difference between tinea capitis and seborrheic dermatitis?

Tinea capitis and seborrheic dermatitis have fundamentally different causes. Tinea capitis is a fungal infection, including conditions such as yellow tinea, white tinea, black dot tinea, and pustular tinea. It leads to the destruction of hair follicles, which can cause hair loss and even scarring. Seborrheic dermatitis, also known as seborrheic eczema, arises from the excessive secretion of sebum. At this time, it may also be stimulated by the colonization of certain microorganisms, such as Malassezia, causing inflammation. It typically affects the scalp, face, chest, and back. The initial lesions are follicular papules, which gradually enlarge and merge into dark red or yellow-red plaques covered with greasy scales or crusts. It can also exhibit exudation, crusting, erosion, and other eczematous changes, and in severe cases, the skin lesions can become widespread throughout the body. To differentiate between tinea capitis and seborrheic dermatitis, besides the symptoms, local skin flakes can be tested in a laboratory using fungal immunofluorescence, as well as bacterial and fungal cultures.
