My hair stylist recommends this brand because she uses the hair color. It’s a dark, pigmented purple. It lathers well and last for a long time. I do find myself using a bit more than a quarter sized Palm amount.
So far, I’ve only tried a handful of purple shampoos but I really like this one. It lasts a decent amount of time. A little bit goes a long way. It’s a pretty dark purple and very pigmented. I can also extend my washes from about 2-3 days to about 4-5 days when using this.
