Heat denatures the keratins (proteins) of the hair shaft weakening it and making it prone to split ends. Heat treatments are a major cause of damage and split ends. This includes hot blow drying, heat styling, straightening and curling through heat, and steam treatments. If you do use these treatments, take these precautions:  Do not straighten or use other high-heat treatments more often than once every two weeks, or preferably once a month. Look for irons or other tools that allow for exact temperature control. Keep them set to below 356ºF (180ºC). Let hair stylists know that you prefer low-heat treatments. Consider applying a special pre-swimming moisturizer product. Alternatively, use a leave-in conditioner, oil your hair, and/or wear a swim cap. Rinsing your hair thoroughly before swimming may reduce its absorption of harmful chemicals. Be sure to rinse and shampoo your hair as soon as possible after swimming. Ultraviolet rays can be as damaging to your hair as your skin. Wear your hair in a bun underneath a hat, or use leave-in sunscreen conditioner Hair dyes, perms, and bleach are particularly damaging, but any product can damage your hair. Try to limit how often you get your hair colored, permed, and bleached. Instead, opt for occasional touch ups to dye and bleach, such as once every 6 to 8 weeks.  For example, if you have dyed or bleached hair, get root touch ups only as needed. Do not re-dye all of your hair every time the roots grow out. If you have a perm, only get it touched up when it is absolutely necessary, or consider not getting it permed again at all if your hair is damaged.
