I liked it at first! Then it started to make my hair feel a little stiff.

Love the product, hate the packaging

The bottle cap it too hard to get open. You have to press so hard to get it open that the bottle itself gives a little. It's a PITA. For that reason I will have to think about whether or not this will be a repeat purchase, especially because it's pretty expensive for bad packaging to be a problem.
