Frequently asked questions
Does Dercos Densi-Solutions Thickening Shampoo contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 6 of the EU-labelled fragrance allergens: parfum, geraniol, hexyl cinnamal, isoeugenol, limonene, linalool. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Dercos Densi-Solutions Thickening Shampoo with caution and patch test before full use.
Is Dercos Densi-Solutions Thickening Shampoo paraben-free?
No parabens were detected in Dercos Densi-Solutions Thickening 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 Dercos Densi-Solutions Thickening Shampoo suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. Dercos Densi-Solutions Thickening Shampoo contains 11 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 Dercos Densi-Solutions Thickening Shampoo against your own profile.
