for color treated and damage hair this is a must! I use this product at least twice a week after coloring my hair.

I'm super annoyed right now. The main problem is the so called "support". I've had some very strange glitches with this thing, such as if I log walking earlier in the day, it then repeatedly subtracts steps later in the day. Their lame-o support people just parrot back a pat answer that "when I log manually, it overrides the steps logged by your fitbit". Huh? That does NOT explain why it would do it, LATER IN THE DAY! So, don't buy this thing. I've already also had it not log steps, and you can't even delete your own account, you have to ask THEM to do it for you, and then they require you to go through multiple layers of lengthy menus just to be able to email them. I wish I had just gone with the apple watch. You get what you pay for. I've had to go through all these hassles, after just owning it for a mere 6 weeks.
