Many people still think it's a myth that hats and rubber bands can cause hair loss in women, but in fact, it's partially true. While hats and ponytails won't actually cause balding, repeated friction and tightly pulled hair can cause localized hair loss and breakage at the hairline. Use coated hair bands and don't pull hair too tightly to keep this to a minimum. Avoid eating too much salt and sugar. You should entirely eliminate both of these from your diet. Eating too much salt or sugar can contribute to hair loss and make it harder to grow your hair back. Most vegetables have their own sodium, so cut back on the salt and you will come to like them even more.
