Tinea capitis may be caused by a fungal infection, but it may also be caused by sweat rash or exfoliative keratosis. Tinea capitis caused by fungal infection is often accompanied by tinea pedis, which is mostly caused by the transmission of tinea pedis. It is usually solitary, that is, it appears on one hand and manifests as deep blisters with itching, and the blisters dry up with flaking and peeling skin. Sweat blisters are caused by exposure to certain allergens, sweaty hands, and many other causes. Treatment is mainly given by topical application of weak hormonal creams, such as hydrocortisone butyrate cream. Exfoliative keratosis requires avoidance of excessive hand sweating, exposure to alkaline detergents, and excessive washing. 10% urea cream can be given to protect the skin.
