Everyone can stand to benefit from deep conditioning—even if your hair isn’t damaged, using a deep conditioner can help prevent split ends and breakage, and give your hair a nice boost of shine and moisture. But, if your hair is damaged in any way, a deep conditioning treatment is a must-do. How often should I deep-condition my hair? You shouldn’t be deep-conditioning your hair daily; once or twice per week is sufficient. How should I apply my deep conditioner? Always use your deep conditioner after you shampoo, never before. And, contrary to popular belief, you should always towel-dry your hair first to make the conditioner more effective.
