Based on its formula, is this conditioner safe for dry and sensitive scalps?

The conditioner is formulated for dry hair and includes soothing ingredients such as panthenol, apricot kernel oil and hydrolyzed keratin, but it also contains fragrance, dimethicone and preservatives like phenoxyethanol that can irritate very sensitive or fragrance-allergic scalps, so users with such sensitivities should perform a patch test.

What is the role of hydrolyzed keratin in Syoss Nutrition Intense 7 Conditioner?

Hydrolyzed keratin supplies small protein fragments that can penetrate the cuticle, helping to replenish lost keratin, strengthen the hair shaft, improve elasticity and reduce breakage, especially on dry or damaged hair.

How often should this conditioner be applied and does it contain any controversial chemicals?

It is intended for use after each shampoo - apply to wet hair, concentrate on the lengths and ends, leave for a few minutes, then rinse - while the formula includes silicones (dimethicone, dimethiconol) and preservatives such as phenoxyethanol and sodium methylparaben, which some consumers consider controversial due to potential buildup or sensitization concerns.

Product Insights

Its formulation combines conditioning agents such as cetearyl alcohol, dimethicone, hydrolyzed keratin, panthenol, apricot kernel oil and glycerin to deliver moisture, smoothness and protein reinforcement to the hair shaft. However, the product also contains fragrance, silicone (dimethicone and dimethiconol), preservatives like phenoxyethanol and sodium methylparaben, and trace allergens (linalool, hexyl cinnamal, benzyl salicylate, geraniol), which may irritate sensitive scalps or lead to silicone buildup with frequent use.
