Bumping this because, OMG!! Because of this thread I just picked this up and wow. I have coarse, permanent colored hair, that is even drier, I think, because there's a lot of gray being covered. It's a frizzy ball of wavy dry hairs. Had been using Kerastase which is beyond expensive for a tiny bottle. This blew it away, after just one washing. My hair is soft and shiny. I don't overwash but do blowdry after every wash. It's somewhat soft after Kerastase, but never shiny unless I use shine serums. With Kirkland's shampoo it is shiny, soft, and frizz free. Thank you, OP!!!
