The Rating: 4.2 stars
Why Customers Love It: Investing in a mask that you can use weekly is totally worth it. This testimonial says it all: "This product changed my hair routine, it's an absolute must. My hair is coarse, thick, and by the end of the week the ends get brittle and dry. I use this in the shower every Sunday and it adds moisture, softness, and shine back into my hair. It's totally changed the way my hair feels throughout the week."
