my hair got like this the last time I tried CG with a mousse... I think it was a polyquat then, but it was so long ago I had almost forgotten. Anyway, that's why I ended up stopping.
My problem was the opposite, my hair would get too oily if I didn't low poo frequently. but now that I think about it, I could have just been transitioning.
I just looked through some old pictures... My hair... Well it was embarrassing. That gave me some extra motivation for CG!
