Look on Makeupalley.com to see reviews and compare the two. I've never used either products. However, I've gotten my hair into MUCH better shape by using these two products:
Frederic Fekkai Protein Rx Reparative Mask (expensive, but smells amazing and restores strength to hair)
Joico K-Pax Intense Hydrator (smoothes, hydrates and helps prevent split ends.. I use this every three days now and my hair has never been better)
HTH!
