5 Stars

The only thing that gets certain products out of my hair. Before this, I did an oil treatment and couldn’t get the oil out for a month, washing it hundreds of times with several different things. Finally, I found this and when I used it- it got it ALL out in one use (I washed it with it twice in one shower.) I am not exaggerating.. my hair has NEVER felt better!
