This is a wonderful conditioner. It leaves my long fine hair super-smooth without feeling heavy or weighed down.

AMAZING!
Amazing! I have wavy/curly hair and this has made it so soft and very manageable, I’ve not had it long enough to see long term results but I trust this brand a lot!

Useless
It was the most useless hair product I’ve ever used. my hair has been a bit damaged because of highlights, it has not done anything positive to the hair, even it doesn’t act as a conditioner, it doesn’t act as a mask , it does nothing!!! You just waste lots of money by this expensive useless product
