When your hair starts to feel dry, brittle, and frizzy, it's time to add some moisture to restore the visible health of your hair. If you're wondering how to infuse moisture into dry hair, the first thing you need to know is that dry hair typically needs additional conditioning.  A rich leave-in treatment, such as nutriplenish daily moisturizing treatment, can help restore and lock in moisture, leaving dry hair feeling nourished and healthier looking throughout the day. For added moisture, combine this product with others in the nutriplenish line, such as nutriplenish multi-use hair oil or a nutriplenish shampoo formulated for dry hair.
