Is this strengthening shampoo suitable for sensitive or dry scalps?

While the shampoo's conditioning agents and niacinamide can help moisturize and reinforce hair, the presence of high-strength sulfates (sodium laureth sulfate and sodium lauryl sulfate) and fragrance allergens such as limonene, linalool, and benzyl alcohol may cause irritation for very sensitive or dry scalp users, making it best suited for normal scalp types.

What benefits does niacinamide provide in this shampoo?

Niacinamide (vitamin B3) improves the scalp's barrier function, reduces inflammation, increases moisture retention in the hair cuticle and strengthens the hair fiber, contributing to reduced breakage and a smoother feel.

How often should this shampoo be used and are there any controversial ingredients to consider?

The product is formulated for daily to every-other-day use; however, it contains sulfates (SLES and SLS) and a synthetic fragrance complex with known allergens, which are considered controversial by consumers seeking sulfate-free or hypo-allergenic hair care.

Product Insights

The Garnier Fructis Stop Agressions Strengthening Shampoo is a 250 ml plastic-bottled formulation aimed at reinforcing hair against mechanical and environmental damage. It combines niacinamide, which supports scalp health and fiber resilience, with amodimethicone and guar hydroxypropyltrimonium chloride to smooth and protect hair strands. However, the formula relies on sodium laureth sulfate and sodium lauryl sulfate as primary surfactants and includes a fragrance blend containing limonene, linalool, benzyl alcohol and other allergens, which may irritate sensitive scalps.

Comparative Analysis

Positioned in the drugstore anti-damage shampoo segment, this Garnier Fructis Stop Agressions product differentiates itself by pairing niacinamide-driven strengthening with silicone-based conditioning while remaining priced for mass-market consumers.
