The Designing Longevity take
Is a fragrance-free scalp formula worth the higher selected bottle price to you? A fragrance-free option with two named peptides and published 30 mL price. The official page also describes scalp hydration; its 5% Capixyl figure measures a blend, not Acetyl Tetrapeptide-3 alone.
What we like
- Full ingredient list and fragrance-free positioning
- One-time 30 mL listing and clear daily-use directions
What to weigh
- The selected bottle is half the volume of The Ordinary’s selected bottle
- The brand’s scalp-comfort results came from a regimen that also used its shampoo and conditioner
Ingredients and evidence
- Peptide ingredients on the checked listing
- Acetyl Tetrapeptide-3, Biotinoyl Tripeptide-1
- Concentration disclosure on the checked listing
- The brand lists 5% Capixyl complex; it does not give the isolated Acetyl Tetrapeptide-3 fraction.
- Directions and precautions on the checked listing
- Brand directions: use daily on damp or dry hair, massage into scalp and leave in. Stop if irritation occurs; rinse if product enters eyes.
What supports the product’s claims?
Brand-reported testing
- Study described by the brand
- Self-reported results from a three-product routine; comparison group and random assignment not disclosed
- People and duration
- 50+ participants used the shampoo, conditioner and scalp serum together for 12 weeks.
- Reported outcome
- 96% said scalp felt hydrated; 96% less itchy; 94% less flaky.
- Comparison group
- Not disclosed on the checked product page
The serum contribution cannot be isolated. These are scalp-comfort reports, not objective hair-regrowth results.
Brand’s study disclosure · Study search checked
We checked public brand pages and product-name searches. A missing report stays unknown; a study of another formula stays separate. These records do not establish which listed product works best.
The ingredient disclosure identifies the listed formula. It does not show that this finished product was tested against other serums here, or that a higher stated complex percentage produces better results.
These are topical scalp cosmetics. An ingredient name or brand survey does not establish that the finished serum treats the cause of hair loss. A dermatologist can assess sudden, patchy or persistent shedding.

Frequently asked questions
What does this review assess?
This review covers The Scalp Serum (30-Day Supply) as a named topical cosmetic listing. It compares published ingredients, selected package information and purchase terms; it is not a hands-on test or a clinical efficacy rating.
Is it available to buy?
In stock when checked. That is a dated observation, not a guarantee of current stock.
Does the product name establish a health benefit?
No. A cosmetic product name or ingredient study does not establish hair regrowth, wound healing or structural changes in skin for this finished formula.
How we compare
We start with a reader’s decision, then separate published facts from our judgment. Government and professional sources support health explanations; a brand’s page supports what it lists, charges or promises. We have not tested these products or assessed individual treatment suitability.
This researched shortlist covers finished topical peptide scalp serums with a public U.S. listing, a named peptide on the ingredient list and usable product details. The separate Mochi catalog entry lacks a full finished label. Feature picks concern disclosed ingredients, product format, bottle size or purchase terms. They do not score cosmetic results or medical quality.
Prices and stock reflect the dated check, with missing facts shown explicitly. We withhold expired quotations and product-shopping links that lack the required label review. Monthly editions advance after a completed source check. Product source links use the brands’ public URLs. This content is not medically reviewed.
Linked guides keep their own source dates and limitations.
For each finished product, we check whether a public human study report identifies the formula, participants, duration, outcome and comparison group. The product details distinguish brand-reported testing, consumer surveys, studies of a whole routine and reports we could not locate. A missing report stays unknown, and an ingredient study cannot stand in for a study of a different finished formula.
