Frequently asked questions

Does Amino Acid Shampoo 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 Shampoo with caution and patch test before full use.

Is Amino Acid Shampoo paraben-free?

No parabens were detected in Amino Acid Shampoo's listed ingredients. Worth keeping in perspective: parabens are among the least common cosmetic allergens, so "paraben-free" matters far less for reactive skin than avoiding fragrance or the preservative MI/MCI.

Is Amino Acid Shampoo suitable for sensitive or allergy-prone skin?

It depends on your specific triggers. Amino Acid Shampoo contains 3 flagged allergens and 1 irritant (listed in the analysis above). If none are on your personal allergen list it may suit you, but patch test first — add your allergens to AllerNote to check Amino Acid Shampoo against your own profile.
