Tinea capitis is caused by fungi of species of genera Trichophyton and Microsporum. Tinea capitis is the most common pediatric dermatophyte infection worldwide. The age predilection is believed to result from the presence of Pityrosporum orbiculare (Pityrosporum ovale), which is part of normal flora, and from the fungistatic properties of fatty acids of short and medium chains in postpubertal sebum.
