Is this shampoo safe for sensitive or dry scalp and hair?

Because it contains strong cleansing agents like sodium laureth sulfate and several fragrance allergens, the shampoo may be too drying or irritating for highly sensitive or dry scalps and is best suited for normal to oily hair types.

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

Zinc pyrithione acts as an antifungal and antibacterial agent that inhibits the growth of Malassezia yeast on the scalp, thereby reducing dandruff, flaking, and associated itching.

How often should this shampoo be used and does it contain any controversial chemicals?

It is typically recommended to use the shampoo 2–3 times per week; the formulation includes sodium laureth sulfate, DMDM hydantoin (a formaldehyde‑releasing preservative), synthetic fragrances, and colourants, which are considered controversial by some consumers.

Product Insights

Shampoo Stop Dandruff Classic Oily is an anti‑dandruff shampoo formulated for oily scalps, featuring zinc pyrithione to reduce flaking and panthenol to provide mild moisturisation. The formula relies on a high concentration of surfactants such as sodium laureth sulfate and cocamidopropyl betaine, and includes synthetic fragrance components and a formaldehyde‑releasing preservative (DMDM hydantoin), which may irritate sensitive skin. Packaged in a 250 ml plastic bottle, the product is classified as ultra‑processed (NOVA 4) and contains synthetic colourants (Yellow 5, Green 5) that could be a drawback for consumers seeking cleaner cosmetics.

Comparative Analysis

Positioned as a classic anti‑dandruff shampoo for oily hair, this product leverages zinc pyrithione for scalp care while differentiating itself with a high‑foaming surfactant base and a citrus‑rich fragrance, yet it contains several synthetic preservatives and colourants that may concern sensitive users.
