The Edyt Score
4.4 / 5.0
Targets
4.4/5
For a thinning part that wants an overnight serum, not only a shampoo. Skip the system kit if this pair is the plan.
Formula standards
4.4/5
Apply to a clean scalp at night. It will not grow a new hairline, and the two bottles are a system.
The verdict
A reasonable density pair for fine roots. Give it a month before judging.
