Really good
Bought this product after reading good reviews but could not even imagine that it really works so well! I have very long colored hair and I never use hairdryer. So I just dry my hair with a towel, use oil and finish with this treatment - and voila, when hair dries up it looks tidy, sooth and shiny!
