2. Symptoms of tinea capitis include circular patches of hair loss, scaling, and redness on the scalp, which can be accompanied by itching and inflammation.
3. Tinea capitis is more common in children than adults, as their immune systems are still developing and they are more susceptible to fungal infections.
4. Severe cases of tinea capitis can lead to the development of a kerion, which is a painful, swollen, and pus-filled mass on the scalp that requires prompt medical treatment.
5. Antifungal medications, both topical and oral, are the primary treatments for tinea capitis, and it is essential to complete the full course of treatment to prevent recurrence or the development of resistant infections.
