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

The shampoo contains sodium laureth sulfate and added fragrance, which can irritate very sensitive or acne-prone scalps, while the hyaluronic acid and glycerin help soothe dry hair; a patch test is recommended, and most users with normal or slightly dry scalps find it well tolerated.

What is the specific role and benefit of hyaluronic acid in this shampoo?

Hydrolyzed hyaluronic acid acts as a humectant, attracting and holding water in the hair shaft, which improves moisture retention, reduces frizz, and enhances elasticity for smoother, more manageable hair.

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

For most hair types, using the shampoo 2-3 times per week is sufficient, though it can be used daily if the scalp tolerates the surfactants; the formula includes sodium laureth sulfate, fragrance, and fragrance allergens such as limonene and linalool, which some consumers consider controversial, but it does not contain parabens or known banned substances.

Product Insights

Shampoo Hialurónico + Vitamina A is a 190 ml, recyclable plastic shampoo marketed by Sedal (Unilever) and certified PETA approved, formulated for hair cleansing and conditioning. Its key actives include hyaluronic acid (hydrolyzed hyaluronic acid) for moisture retention, vitamin A (retinyl palmitate) for scalp nourishment, and glycerin, while surfactants such as sodium laureth sulfate and cocamidopropyl betaine deliver foam and cleansing power. Potential irritants are the added fragrance (parfum) and fragrance allergens like limonene, linalool and citronellol, and the presence of sodium laureth sulfate may be harsh for very sensitive scalps, so users with such concerns should patch-test before full use.
