Frequently asked questions
Is T/Sal® Therapeutic Shampoo-Scalp Build-Up Control fragrance-free?
No added fragrance or EU-labelled fragrance allergens were detected in T/Sal® Therapeutic Shampoo-Scalp Build-Up Control's listed ingredients. "Not detected" isn't an absolute guarantee, but it's a good sign for fragrance-sensitive skin — confirm against the current pack and your own triggers.
Is T/Sal® Therapeutic Shampoo-Scalp Build-Up Control paraben-free?
No parabens were detected in T/Sal® Therapeutic Shampoo-Scalp Build-Up Control'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. T/Sal® Therapeutic Shampoo-Scalp Build-Up Control contains 1 flagged allergen and 2 irritants (listed in the analysis above).
