No Difference With This Product
This didn't do anything bad to my hair, but I couldn't tell a difference at all. My hair has the normal amount of frizziness, volume, etc. I'm through about 3/4 of the bottle (I've continuted to use it in case it took continued use to have impact). I will continue to use this bottle in case it is protecting my hair from the flat iron, but will not repurchase. Chi has some great products (the keratin spray and silk infusion come to mind), but this is not one of them.
For reference, my hair is long (past bra strap) and thick with loose waves, which I flat iron every other day with the Sedu Revolution. This product might have more of an impact if you have curlier/coarser hair.
