How to Treat Tinea Capitis (Scalp Ringworm)

Scalp ringworm (tinea capitis) not only severely affects the skin but also significantly impairs one’s physical appearance. If left untreated, it may spread to other areas of the face, causing substantial cosmetic damage.

How to Treat Scalp Ringworm

Scalp ringworm can be treated with ketoconazole shampoo for antifungal cleansing. Subsequently, topical antifungal agents—such as sulfur ointment or terbinafine cream—should be applied directly to the affected areas. For patients experiencing severe, intolerable pruritus, adjunctive treatment with hydrocortisone butyrate cream or halometasol cream may be used to relieve itching and reduce inflammation. With consistent adherence to therapy, most cases show marked improvement. Patients who respond poorly to topical treatment may require systemic oral antifungal therapy. Commonly prescribed oral agents include itraconazole capsules and ketoconazole capsules. As antifungal medications impose a certain burden on hepatic function, liver function tests must be performed prior to initiating treatment; these drugs are contraindicated in patients with impaired liver function or should be used only under strict medical supervision.

Knowledge Expansion: Causes of Scalp Ringworm

1. Direct and Indirect Transmission

Close contact between healthy individuals and those infected with scalp ringworm—especially among children playing together and engaging in head-to-head contact—readily facilitates transmission. Direct transmission also occurs following contact with infected animals. Indirect transmission may occur via shared personal items such as hats, scarves, pillows, combs, hair clippers, or scissors previously used by an infected individual. Thus, scalp ringworm is highly contagious.

2. Fungal Infection

Scalp ringworm is a superficial fungal infection affecting the scalp and hair. Based on causative fungi and clinical manifestations, it is classified into tinea flava (favus), tinea alba (white ringworm), tinea nigra (black dot ringworm), and kerion (inflammatory ringworm). In China, common causative dermatophytes include *Trichophyton schoenleinii*, *Microsporum ferrugineum*, *Microsporum canis*, *Trichophyton violaceum*, and *Trichophyton tonsurans*. Trauma to the scalp—such as that caused by shaving—increases susceptibility to infection; thus, barbering constitutes one potential route of transmission.

3. Allergic Reactions

Allergic reactions manifest in numerous ways, and scalp ringworm may occasionally result from hypersensitivity. If scalp ringworm arises from an allergic cause, prompt medical evaluation is essential. Allergen testing at a hospital can help identify specific triggers; once identified, avoidance of the offending substances—including certain foods or environmental agents—is critical to prevent worsening allergic responses.

The above outlines treatment options and underlying causes of scalp ringworm. We hope this information proves helpful.
