ive been using it for neglect method for about 4 months..... my hair has been growing for almost 2 years and the bottom half of my hair is knotting up pretty good and stuff on top is starting to. i wash my hair almost everyday. it gets very dirty from racing offroad motorcycles and i cant stand the stink. ive tried dr broners and prell seems to clean better and leave less residue. plus i like the way it smells.
