Frequently asked questions

Does Amino Acid Conditioner contain fragrance allergens?

Yes — analysing the INCI list, AllerNote found 2 of the EU-labelled fragrance allergens: parfum, coumarin. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Amino Acid Conditioner with caution and patch test before full use.

Is Amino Acid Conditioner paraben-free?
