I know this post seems to be over with already, but I thought I'd add the information for anyone who is still wondering if they should try the product or not.
I actually did a month trial of this shampoo, just because I was curious enough and secure with the amount of locking I have so far. Before this shampoo I just used Dr Bonner's products. I wash my hair 3 times per week (may be a lot for some, but my hair does best with this schedule). When I first started it seemed to work great. I was a little put off by how strong the fragrance was after, because it has to be leaving something to leave the fragrance behind, but i continued none-the-less. Slowly my hair started dulling over time. I do use oils in my hair, but it seemed that I couldn't get it back to the way it used to be. My hair looked depressed to me. I finally started with Dr Bonner again and after the first wash, all these clumps of white things were at the roots after shampooing twice (I usually shampoo once since I do wash frequently). Beneath the white string like things was the shine to my hair. Still a little duller than it was previously, but at least I know the answer. The rest of the bottle of Pure&Clean is going to my daughter. I'm sticking with Dr B, raw honey, raw coconut oil, horsetail rinses, and my oils.
