This mask genuinely delivers. My hair was dry and damaged from coloring, and after just the first use it felt noticeably softer and more manageable. Less breakage, less frizz, and split ends look better too.

I ran out after 7 months of use and was without it for 1 month…my hair totally suffered. I am grateful that I could afford to buy one for myself. My hair perked up immediately after the first use. Love this product. I’m 86 this month. My hair is amazing.
