I love this product...my hair dresser 1st used this on my color treated hair. I do have very thick, short, color treated hair. Leaves my hair soft and manageable to style, and I love the scent! I buy multiple bottles when it's on sale.

The directions say to spray in damp hair, so I did. My hair was damp and I sprayed from root to tip. I then blow dried my hair. My hair felt so greasy and I didn't like that!!
I will not buy again
Hair Type Wavy Hair
Too heavy on hair.
So good!
Hair Type Wavy Hair
Makes my hair so soft and shiny, when I air dry I don't use much or it will make my hair greasy faster, but when styling never had a problem with that
LOVE IT!!
Absolutely in love with this product!! Definitely worth the money. Helps my hair dry faster which is a plus because I have thick hair.
