I had it done for the first time about a month ago. I was thrilled with it but now it is already wearing off.
I am wondering how long your treatments have stayed for you? I heard that sometimes it doesn't take as well the first time and lasts longer each time you do it. It is far too expensive and time consuming to do this monthly so I'd like to see what other peoples experiences have been before doing it again.
BTW, I really love Deva One Condition
. An all around great conditioner. I like the Pureology shampoo also but haven't tried their conditioner. I also use Deva no-poo sometimes.
