Our assessment
Start here if your main decision is whether to add a leave-in scalp-care step at all. It gives you a sensible comparison anchor: would a more expensive product solve a particular problem for you, such as dispensing, fragrance preference or local availability? If you cannot name that advantage, the upgrade has not yet justified itself.
The most common mix-up is with The Ordinary’s copper-peptide facial serum. The hair-density product and the facial product are different formulations with different intended use. A search result containing the words “multi-peptide” is not enough to identify the bottle.
For a first purchase, judge the routine as well as the label. Consider whether a bedtime application is practical, whether the product sits comfortably alongside your usual washing schedule, and whether you would be happy to repurchase without a promotional discount. We have not tested its feel or measured hair counts.
Reasons to consider it
- Two identifiable cosmetic peptides
- No added parfum in the checked ingredient list
- Accessible price positioning
Trade-offs to weigh
- No copper peptide in this formula
- Does not establish treatment of female pattern hair loss
- A complex ingredient list makes individual effects hard to isolate
What the evidence supports
The brand describes improvements in the appearance of thickness and fullness. That is a cosmetic claim; it does not make this serum an established substitute for a hair-loss medicine.
We have not tested this product or measured hair counts. Product placement reflects ingredient transparency and shopping fit, not a claim of superior regrowth. Read our guide to clinical claims.
Routine considerations
The brand directs application of a few drops to a clean, dry scalp, ideally at bedtime. Follow the current bottle instructions and its patch-test guidance.
