Smell like Rotten Fish

This product horrible!!! I do not recommend. Had to spray hair perfume all over my just washed and styled hair because this stunk so much!

Amazing

[This review was collected as part of a promotion.] I love this! I have fine thin hair and it makes my hair so soft. And the heat protection is a bonus!!
