Rated 5 out of 5 by Amanda from The best hair product EVER! Its literally the only hair item I am loyal to. If this product ever gets discontinued I will probably just shave my head. The best thing ever for processed hair.

Rated 5 out of 5 by EKK29 from Amazing!! My hair is soooo healthy. It used to die so fast but after using this serum it’s been fine!

Rated 5 out of 5 by Sunshine from love love love This is the second bottle for me and I can't begin to tell you all the benifits it had given me for my hair! This is such a great product if you have long hair and I can tell you I have LONGGGGGGG hair.

Rated 4 out of 5 by Jeni from Trying tro cool things down! Going from a level 8 red to a cool blonde can be challenging to say the least, so after having a Wella color class our educator suggested I give Color Renew a try...so far so good. My hair feels good and it defiantly lifted some warm tones from my ends!
