I'm on my second bottle. I use it after every wash. I have no complaints at all. I got a touch up almost 2 weeks ago and this was the first time that my stylist had NOTHING to say! Nothing! She didn't have to trim either! No, I take that back she did say "you're in really good shape girl." I've been doing a few things including conditioner washes and extra moisutrinzing so I really don't know how effective the Stregthener Treatment really is. The ingredients are all good so I figure it can't be doing any harm. Try it and let me know what you think.
