The Edyt Score
4.4 / 5.0
Targets
4.4/5
For breakage at the wash. Skip the pair if only this bottle is needed.
Formula standards
4.4/5
A liquid shampoo. Ends may still feel dry without a conditioner, and it will not lengthen a hairline.
The verdict
The single shampoo if that is the empty bottle. One wash.
