Other long-term effects may occur, but they depend on the cause of the hair loss. Many cases of hair loss in children are due to fungal infections. These are fairly contagious and can be spread by close contact with other children or sharing combs or hairbrushes. Syphilis , a sexually transmitted disease , is a rare cause of hair loss. Other forms of hair loss, which make up the majority of cases, are not contagious.
Treatment is directed at the underlying cause.
Some people may choose hair grafting, or hair transplantation, to cover areas of hair loss. Wigs, hair weaves, toupees, and other hairpieces may be used to cover areas where hair is thin or absent. Other treatments may be used for other causes. Some people choose no treatment at all. All medications may cause side effects.
