If your hair is excessively dry, you may be tempted to double up on moisturizers by using a conditioner after your hair mask. Though in this case, more is not always better.
Hair masks are high-power conditioning solutions that can deeply nourish and strengthen your hair. They infuse your strands with desperately-needed hydration; however, too much conditioning can saturate your locks, leading to dull, limp hair.
To achieve maximum benefit, apply your hair mask once or twice a week in place of your regular conditioner.
