Frequently asked questions
Does Sleek & Shine Smoothing Conditioner contain fragrance allergens?
Yes — analysing the INCI list, AllerNote found 5 of the EU-labelled fragrance allergens: parfum, hexyl cinnamal, benzyl alcohol, linalool, amyl cinnamal. If you're fragrance-sensitive or patch-test positive to a fragrance mix, treat Sleek & Shine Smoothing Conditioner with caution and patch test before full use.
Is Sleek & Shine Smoothing Conditioner paraben-free?
No parabens were detected in Sleek & Shine Smoothing Conditioner'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 Sleek & Shine Smoothing Conditioner suitable for sensitive or allergy-prone skin?
It depends on your specific triggers. Sleek & Shine Smoothing Conditioner contains 6 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 Sleek & Shine Smoothing Conditioner against your own profile.
