Frequently asked questions
Does Nourishing Shampoo contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 2 of the EU-labelled fragrance allergens: lavandula angustifolia oil, salvia sclarea oil. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Nourishing Shampoo with caution and patch test before full use.
Is Nourishing Shampoo paraben-free?
No parabens were detected in Nourishing 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 Nourishing Shampoo suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. Nourishing Shampoo contains 4 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 Nourishing Shampoo against your own profile.
