【New, Unused, Unopened】Advanced Clinicals Advanced Clinicals Keratin Hair Mask Hair Pack Non-Sticky Large Capacity 340g KERATIN Thank you for viewing. Purchased from IHerb in December 2025. 【Generous, Large Capacity】A generous 340g capacity, perfect for daily hair care! Even those with long hair can use it lavishly, enjoying salon-quality hair care easily at home. 【Smooth, Silky Hair with High-Quality Keratin】Contains keratin, a hair-protecting ingredient. The light, non-sticky texture gently envelops the hair, leaving it moisturized and manageable. 【Shiny Hair with Naturally Derived Ingredients】Formulated with naturally derived shea butter and silk amino acids. It protects the hair's moisture, preventing dryness and frizz, while making hair smooth and shiny. 【How to Use】STEP 1: After showering, gently wrap your hair in a towel and towel-dry to absorb excess water. The key is to gently sandwich your hair with the towel, rather than rubbing it. STEP 2: Apply the hair mask. Take an appropriate amount of the hair mask in your hand and, being careful not to get it on your scalp, apply it from the middle of your hair to the ends. Gently massage it in to distribute it throughout your hair, leave it on for a few minutes, and then rinse. Use it once a week, but if you are particularly concerned about damage, use it 2-3 times a week. 【Recommended for those who】Are looking for a large-capacity keratin product that can be used daily.
