What is the treatment for black dot tinea capitis?

Black dot tinea capitis, also known as dermatophyte infection of the scalp, typically requires systemic treatment due to the nature of the fungal infection and the depth of involvement. Oral antifungals are effective because they can penetrate the hair follicles and the scalp's deeper layers, where the infection resides. This ensures a comprehensive approach to eliminate the fungus, which is essential since topical treatments may not adequately address the issue once the infection is established deeply in the hair follicles.

Topical antifungals generally are more appropriate for surface fungal infections or mild cases, while systemic therapy is usually indicated for more extensive infections like black dot tinea capitis, where the fungus can be more challenging to reach and eradicate with topical options alone. Antibiotic therapy and antiviral medications are not effective treatments for fungal infections, including tinea capitis, as they target bacteria and viruses respectively, not fungi. Hence, the most effective treatment for black dot tinea capitis is oral antifungals.
