Hair Regardless of your hairstyle, all hair should be clean and brushed/combed in the back as well as the front. (Don’t laugh—many people forget to check the BACK of their heads. So while they look great entering a room, they end up looking terrible when leaving!) If you have trouble with dandruff or other scalp conditions, contact a physician or dermatologist who can prescribe an appropriate shampoo or cleansing regimen.
