Most cases of increased shedding gradually resolve on their own without treatment, Schlosser says. But if your hair doesn't return to its normal fullness after six to nine months, see a doctor for an evaluation to find out if something else is going on. If you ever have any symptoms like itching, pain, burning, flaking, redness, or notice you can't see as many hair follicles anymore, you should seek help sooner. See your primary care provider or go directly to a dermatologist who specializes in treating hair loss. They can determine what type it is and what the right treatment approach is for you.
