Shoppers who want copper peptides and are comfortable with aromatic oils.
Fragrance-sensitive shoppers, or anyone who expects a cooling sensation to prove efficacy.

Our assessment
Divi earns its place in this shortlist because the label actually names Copper Tripeptide-1. That makes it relevant to a copper-specific search in a way that many general hair-density products are not. It does not tell us the concentration or establish a superior result.
The sensory formula is the main trade-off. Some shoppers enjoy a recognisable scent as part of a routine; others actively avoid it. Our fragrance filter includes essential oils even if a label does not use the word “parfum”, because that distinction is more useful for shopping.
Compare the 30 ml bottle against the exact sizes of alternatives before choosing a subscription. A lower first-order total can obscure a different replenishment schedule. We would begin by comparing ordinary purchase terms, then assess any recurring plan separately.
Reasons to consider it
- Copper peptide clearly named in the formula
- Also includes a second cosmetic peptide
- Small bottle available for trying the routine
Trade-offs to weigh
- Essential oils and menthol may not suit every scalp
- Small bottle makes repeat-purchase cost worth checking
- Consumer perceptions are not objective regrowth measurements
What the evidence supports
The brand publishes a 12-week consumer-perception study with 31 participants. Self-reported fullness or comfort is useful context, but cannot establish how much new hair grew or how the product compares with treatment.
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
Use according to the selected bottle’s directions. Do not use a tingling or cooling sensation as a reason to apply more.
Buying in the US and Europe
The brand lists European standard delivery of 5–15 business days, with 10–25 for the Baltic states. Confirm destination and the delivery estimate at checkout; this is not a rapid-delivery promise.
