Is this conditioner safe for sensitive or dry scalps?

The conditioner contains fragrance allergens and preservatives that can irritate sensitive skin, so while it may moisturize a dry scalp, users with sensitivity should perform a patch test or choose a fragrance-free alternative.

What is the role and benefit of zinc pyrithione in this conditioner?

Zinc pyrithione is an antifungal agent that targets the yeast Malassezia, helping to reduce dandruff and soothe an itchy scalp while the surrounding conditioning ingredients keep hair soft.

How often should this anti-dandruff conditioner be used, and does it contain any controversial chemicals?

It is intended for use after each shampooing, typically daily, and the formulation includes dimethicone for smoothness as well as the preservatives methylchloroisothiazolinone and methylisothiazolinone, which have been questioned for their irritation potential.
