Based on its formula, is this shampoo safe for sensitive, acne‑prone, or dry scalp/hair?

The shampoo contains sodium laureth sulfate and fragrance, which can be harsh for very sensitive or dry scalps, and the citrus acids may cause stinging on compromised skin; however, its anti‑sebum agents and menthol are well‑suited for oily, acne‑prone scalps where excess oil is the primary concern.

What is the specific role and benefit of piroctone olamine in this shampoo?

Piroctone olamine is an antifungal agent that targets the Malassezia yeast responsible for dandruff, reducing flaking and itching while supporting a healthier scalp microbiome.

What is the optimal application frequency for this shampoo, and does it contain any controversial chemicals?

For oily, dandruff‑prone hair, using the shampoo 2–3 times per week is typically sufficient; the formula includes controversial ingredients such as sodium laureth sulfate (a strong surfactant), phenoxyethanol (a preservative) and synthetic colorants, which some consumers prefer to avoid.

Product Insights

This citrus‑scented anti‑dandruff shampoo is formulated for oily, flaky scalps, featuring ingredients such as piroctone olamine, menthol, niacinamide and citrus acid that help control excess sebum and reduce dandruff. It also contains potentially irritating components like sodium laureth sulfate, fragrance (parfum), synthetic colorants (CI 42090, CI 47005, CI 77891) and preservatives such as phenoxyethanol, which may not suit sensitive or dry scalp types. Packaged in a recyclable plastic bottle and sold under the Ultrex brand at Mercadona, the product balances effective scalp treatment with a relatively high level of synthetic additives.
