Tinea capitis requires systemic treatment because antifungal creams are unable to penetrate the hair shaft sufficiently to clear the infection. Furthermore, the use of topical antifungal treatment alone may contribute to the creation of carriers. The concept of carriers is controversial but describes patients whose symptoms and clinical sings are mammal but who are still mycologically positive and presumed capable of transmitting infection.
The only licensed treatment is oral griseofulvin. It is usually given at a dose of 10mg/kg for six to eight weeks. However, T. tonsurans seems resistant in some cases, and longer treatment may be required at doses of up to 20- 25mg/kg. Because treatment takes a long time. Higgins et al (2000)
