Frequently asked questions
Does Hair Restore Strength + Purity Shampoo contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 1 of the EU-labelled fragrance allergens: parfum. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Hair Restore Strength + Purity Shampoo with caution and patch test before full use.
Is Hair Restore Strength + Purity Shampoo paraben-free?
No parabens were detected in Hair Restore Strength + Purity 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.

It depends on your specific triggers. Hair Restore Strength + Purity Shampoo contains 3 flagged allergens and 2 irritants (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 Hair Restore Strength + Purity Shampoo against your own profile.
