Our moisturizing hair mask is carefully formulated with collagen and Moroccan argan oil. Designed specifically to infuse moisture into hair and relieve dryness. Very convenient to use: 1. Put on gloves and apply a suitable amount of mask evenly onto dry hair. 2. Let it sit for 15–20 minutes so that the nutrients penetrate deeply into the hair. 3. Thoroughly rinse off the mask with clean water, then dry it with a hair dryer or let it air dry naturally. Additionally, you can add color to create more uniform hair color.
