Ok ladies...I have the worst case of itchy scalp... first off let me say there isn't any build up or flakes and I moisterize my hair and scalp twice a day and with things that I have used before with no ill effects... the only thing that I have changed is that I started taking supplements (only a couple of days ago though) included in those were Biotin, MSM, silica, evening primrose and some other stuff... could it be growth already or if not that what could it be? I co-wash my hair about twice a week and DC once BTW
