Peptide Hair Serums on TikTok: Density vs. Resistance Claims Reviewed
A TikTok clip contrasts The Ordinary Multi-Peptide Serum for density with Kérastase for anti-hair-fall. We fact-check the peptide evidence behind these claims.
Takeaways
- Peptide hair serums show promise in small studies, but evidence is not conclusive.
- Density and resistance are not mutually exclusive; both products may affect multiple pathways.
- Clinical data for specific consumer blends is often limited or industry-funded.
- For research use, purified peptides with known sequences are preferable to cosmetic formulations.
- Individual hair loss causes require tailored approaches beyond any single serum.
Transcript
1. The Ordinary Multi-Peptide Serum 🧪 • The Goal: Density & Fullness. • How it works: Uses advanced peptide technologies to target the hair follicle. • Best for: If your hair feels thin or you want to see more "mass" and volume. • The Vibe: Scientific, affordable, and effective. 2. Kérastase Genesis Sérum Anti-Chute 🛡️ • The Goal: Anti-Hair Fall & Strength. • How it works: Uses Aminexil and Ginger Root to reinforce the hair at the root and prevent breakage. • Best for: If your hair is shedding due to stress or snapping during brushing. • The Vibe: Luxury care that keeps your hair anchored and strong. The Bottom Line: ✨ The Ordinary = For DENSITY (more hair). @The Ordinary ✨ Kérastase = For RESISTANCE (less hair fall). @Kérastase #hairserum #kerastase #scalphealth #hairgrowth #theordinary

Clip claim
The TikTok clip claims The Ordinary Multi-Peptide Serum increases hair density via peptides, while Kérastase reduces hair fall via Aminexil and ginger root.
Verdict

Source material
Caption/transcript used as seed for original rewrite.
A viral TikTok clip by creator Lalmaseli compares two popular hair serums: The Ordinary Multi-Peptide Serum and Kérastase Genesis Sérum Anti-Chute. The video claims The Ordinary targets hair follicle density and fullness using “advanced peptide technologies,” while Kérastase focuses on reducing hair fall with Aminexil and ginger root. The clip’s bottom line: The Ordinary for density (more hair), Kérastase for resistance (less hair fall). But what does the research actually support?
What the clip claims
The clip positions The Ordinary as a science-backed, affordable option for increasing hair mass and volume, implying its peptide blend directly stimulates follicles to produce more hair. It also suggests Kérastase works primarily on root reinforcement to prevent breakage, with less emphasis on peptide mechanisms.
What research neighborhood actually covers
Peptides like copper peptides (e.g., GHK-Cu) have been studied for wound healing and hair follicle stimulation in vitro and in small human trials. However, The Ordinary’s Multi-Peptide Serum contains a proprietary blend—including acetyl tetrapeptide-3, trifluoroacetyl tripeptide-2, and others—that has limited published clinical evidence specifically for hair density. A 2015 study on a similar peptide complex (including acetyl tetrapeptide-3) showed increased hair count and thickness, but it was industry-funded and small. For Kérastase, Aminexil is a well-known ingredient in anti-hair-loss products, with some clinical data supporting reduced hair fall, but the peptide component is less central.
Limits of the evidence
Neither product has robust, peer-reviewed trials demonstrating “more hair” or “less hair fall” in diverse populations. Most studies are short-term, sponsored, and use subjective endpoints. The distinction between density and resistance is oversimplified; hair loss often involves both follicle miniaturization and breakage. Additionally, individual results vary based on underlying causes (e.g., androgenetic alopecia, telogen effluvium), which the clip does not address.
Research-use caveat
For researchers and RUO customers, these consumer serums are not equivalent to purified peptides used in controlled studies. The concentrations, delivery systems, and excipients differ. Always verify the specific peptide sequences and purity for any experimental use. This article is for informational purposes only and does not constitute medical advice.
Questions this watch page answers
Does The Ordinary Multi-Peptide Serum actually increase hair density?
Limited evidence suggests some peptide complexes may improve hair count, but no large-scale independent trials confirm this specific product's efficacy.
Is Kérastase Genesis effective for hair fall?
Aminexil has some clinical backing for reducing hair fall, but results vary and the product's peptide role is less studied.
Can I use these serums for research purposes?
For RUO, use purified peptides with documented purity and sequence, not cosmetic formulations with proprietary blends.
