Alopecia can affect patients of all ages, from newborns to the elderly, and may occur for a variety of reasons; some causes include genetics, autoimmunity, and physical or emotional stress. Some cases are more easily reversible than others. Treatment of alopecia depends on the cause and may include topically applied solutions or foams, scalp injections, or even oral medications. If our providers suspect an internal cause of the alopecia, we may order specific blood tests to help make the diagnosis.
