Frequently asked questions

No added fragrance or EU-labelled fragrance allergens were detected in Multi-Peptide Serum for Hair Density's listed ingredients. "Not detected" isn't an absolute guarantee, but it's a good sign for fragrance-sensitive skin — confirm against the current pack and your own triggers.
Is Multi-Peptide Serum for Hair Density paraben-free?
