Certain chemicals found in shampoos, hair dyes, and other hair treatments can damage the scalp and cause hair to fall out.
If you've recently started a new treatment for your hair or scalp, you should stop this treatment immediately. If a chemical is the cause of hair loss, you can expect your hair to begin to grow back within 8 to 12 weeks.
If your hair is not growing back normally after stopping the product, call your doctor's office for advice.
