Based on its formula, is this shampoo safe for sensitive or dry scalps?

The product contains Sodium Laureth Sulfate and fragrance allergens, which can be irritating for very sensitive or dry scalps; users with such conditions may prefer milder, sulfate-free or fragrance-free alternatives, though the presence of glycerin and Polyquaternium-7 does provide some soothing and conditioning effects.

What is the role and benefit of Violet 2 (CI 60730) in this shampoo?

Violet 2 (CI 60730) is a synthetic violet pigment that deposits a subtle purple hue on the hair, counteracting yellow and brassy tones in blonde or highlighted hair and thereby enhancing cool, silvery shades.

What is the recommended frequency of use for this product, and does it contain any controversial chemicals?

For best results, the shampoo should be applied 2-3 times per week or after each bleaching session, and it does contain ingredients that some consumers consider controversial, such as Sodium Laureth Sulfate (a strong surfactant) and DMDM Hydantoin (a formaldehyde-releasing preservative) along with fragrance allergens like Linalool and Limonene.

Product Insights

The Biorene Silver Intensive Deblonding Shampoo is a 200 ml plastic-bottled product designed to neutralize brassiness in blonde or light-colored hair using violet colorant CI 60730. Its formulation combines cleansing surfactants such as Sodium Laureth Sulfate, Cocamidopropyl Betaine and PEG-4 Rapeseedamide, conditioning agents like Glycerin and Polyquaternium-7, and a small amount of fragrance, but also includes potential irritants such as DMDM Hydantoin, fragrance allergens (Linalool, Citronellol, Limonene, Hexyl Cinnamal, Alpha-Isomethyl Ionone) and the strong detergent Sodium Laureth Sulfate. Overall, the product offers effective toning and moisturizing benefits for yellow-tone control, while users with sensitive scalps or fragrance allergies may experience irritation.

Comparative Analysis

Marketed as an intensive silver-toning shampoo for brassy hair, it differentiates itself from standard anti-yellow shampoos by featuring a higher concentration of violet dye (CI 60730) for pronounced brassiness neutralisation, while its overall surfactant and preservative profile aligns with typical premium hair-care formulations.
