Does The Ordinary Multi-Peptide Serum for Hair Density contain parabens, sulfates or fragrance?
A straight yes or no for the ingredient groups people most often want to avoid, checked against this product's published formulation.
Free from parabens
Preservatives; the longer-chain ones (propyl, butyl) carry the endocrine questions.
Free from sulfates (sls / sles)
Strong cleansing agents that can strip a compromised barrier.
Free from silicones
Slip and occlusion; cyclic silicones (D4/D5/D6) are the environmentally restricted ones.
Free from fragrance / parfum
Undisclosed fragrance blends are the most common trigger for sensitised skin.
Free from essential oils
Naturally derived, but among the most frequently reported contact allergens.
Contains drying alcohol
Found: phenoxyethanol. Fine in small amounts for texture; high up the list it can dehydrate.
Free from formaldehyde releasers
Preservatives that slowly release formaldehyde.
Free from chemical uv filters of concern
Restricted or debated filters with endocrine or reef-persistence questions.
Is The Ordinary Multi-Peptide Serum for Hair Density non-comedogenic?
No ingredients in this formulation appear on Selenssa's common pore-clogger list, so it is unlikely to be the cause of congestion for most people. Comedogenicity is still individual — texture, occlusion and how much you use all play a part.
Is The Ordinary Multi-Peptide Serum for Hair Density safe for sensitive skin?
Generally a reasonable choice for sensitive skin.
- No fragrance or parfum in the list
- Contains a drying alcohol
- No ingredients flagged for irritation risk
