Hair masks are the solution when you experience extremely dry, damaged hair. These extra-strength treatments provide the extra moisture and repair that you need from time to time…or all the time. Pros recommend using a hair mask once or twice a week—even more often if needed. Leave it on for at least five minutes or so, and for even better results, activate your mask with heat. Be sure to choose the mask that’s best for your hair type—Matrix has a wide range of highly effective choices!
