The Edyt Score
4.1 / 5.0
Targets
4.1/5
For brass on treated blonde. Skip No.6 if this wash is the only need.
Formula standards
4.1/5
It can dry the ends, so follow with conditioner. Leave it on too long and hair can look gray-lilac.
The verdict
A fine purple shampoo if brass is the complaint. Use it a few times a week, not daily.
