Is this keratin shampoo safe for sensitive scalps or color-treated hair?

The shampoo contains sodium laureth sulfate and fragrance allergens, which can be irritating for very sensitive scalps, and the presence of strong surfactants may strip color; thus, it is best suited for normal to resilient hair and may not be ideal for highly sensitive or freshly colored hair.

What role does hydrolyzed keratin play in this shampoo?

Hydrolyzed keratin is a low-molecular-weight protein that can temporarily coat hair strands, helping to fill gaps in the cuticle, improve smoothness and reduce breakage, giving the appearance of stronger, shinier hair.

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

For most users, applying the shampoo 2-3 times per week is sufficient to benefit from the keratin while minimizing exposure to the harsh surfactants; the formula includes methylchloroisothiazolinone and methylisothiazolinone, preservatives that have raised concerns for skin sensitization, so individuals prone to allergies should patch-test before regular use.

Product Insights

Keratin Shampoo is a 750 ml keratin-enriched shampoo formulated for hair cleansing and strengthening. Its formula combines hydrolyzed keratin, a protein that can help reinforce hair fibers, with typical surfactants such as sodium laureth sulfate, cocamidopropyl betaine and cocamide DEA for foam and cleaning. The product also contains fragrance allergens (butylphenyl methylpropional, hexyl cinnamal, linalool) and the preservatives methylchloroisothiazolinone and methylisothiazolinone, which may irritate sensitive scalps, and it uses conventional synthetic detergents rather than milder or natural alternatives.

Comparative Analysis

Positioned as a protein-rich, salon-style shampoo, this keratin formula targets consumers seeking repair for damaged or chemically treated hair while competing with other strength-focused shampoos that rely on similar synthetic surfactants and fragrance blends.
