The Edyt Score

4.4 / 5.0

Key ingredients 4.3/5

Extreme Length shampoo alone. The strengthening wash without the conditioner.

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.
