I really liked the results but I ended up buying the rest of the SUPERNOVA line which has been perfect in terms of keeping my hair healthy and toned. I don’t often use styling treatments so this has been left untouched, figured someone else could benefit from this *almost full* bottle of good stuff :). ***
