If you blow-dry your hair regularly, it is important to pamper your locks as much as possible. A major, though often overlooked, part of hair care is a regular haircut. Especially with hair that is frequently exposed to heat styling, once split ends start, they can quickly travel up the hair shaft. Untrimmed hair will often look bushy or frizzy at the ends, ruining an otherwise perfect style. Regular trimmings – every two to four weeks for a short cut, and every six to eight weeks for a longer style – will prevent the added damage that can be caused by a lack of preventative care. In general, if you follow the rules of conscientious blow-drying and keep your hair trimmed, moisturized, and otherwise well cared for, a little heat every day won’t hurt.
