Rated 5 out of 5 by from Fabulous! [This review was collected as part of a promotion.] Firstly this smells great and that’s a bonus! Secondly using this prior to drying my hair, my hair feels smooth and it’s super easy to get a brush through. My hair looks super smooth and sleek and I’d definitely recommend this and will be purchasing in the future.

Rated 5 out of 5 by from Great [This review was collected as part of a promotion.] It is great for repairing damaged hair. My hair is damaged and I have been looking for so lo g to find something that really make a change. I have tried so many things but none of them seems working.
