You can also help prevent dry hair by avoiding some of the hair care products or services that can dry or damage hair. Limit your exposure to the heat from curling irons, blow dryers, and flat irons. Avoid treatments that can dry out your hair, such as coloring, relaxing, or permanents.
It's also a good idea to protect your hair from the UV rays of the sun by wearing a hat when outdoors, and to avoid swimming in chlorinated water if possible. If you do swim in chlorinated water, use a deep-conditioning product or a special conditioner for swimmers to help restore lost moisture.
