Is Ultra Density shampoo safe for a sensitive scalp or dry hair?

The formula includes Sodium Laureth Sulfate and fragrance allergens (Linalool, Limonene), which can irritate very sensitive scalps, while conditioning agents such as Polyquaternium-11 help moisturize dry hair; people with extreme sensitivity or dryness may prefer a sulfate-free, fragrance-free alternative.

What is the role of Cocamidopropyl Betaine in Ultra Density shampoo?

Cocamidopropyl Betaine is a gentle amphoteric surfactant that boosts foam, reduces the irritation potential of Sodium Laureth Sulfate, and helps keep the scalp and hair hydrated during cleansing.

How often should Ultra Density shampoo be used, and does it contain any controversial ingredients?

Use the shampoo 2-3 times per week for normal scalps, or daily if dandruff is persistent; it contains controversial ingredients such as Sodium Laureth Sulfate, DMDM Hydantoin (a formaldehyde releaser), and methylisothiazolinone/methylchloroisothiazolinone preservatives, which may cause irritation in sensitive users.

Ultra Density Shampooing densifiant antipelliculaire

Hair

Product Insights

Ultra Density shampoo is a men's hair-densifying, anti-dandruff shampoo marketed in France. Formulated with cleansing surfactants such as Sodium Laureth Sulfate and Cocamidopropyl Betaine, conditioning polymers like Polyquaternium-11, and scalp-soothing agents including Cetrimonium Chloride, it aims to reduce flakes while adding volume to thinning hair. However, the formula also contains fragrance allergens (Linalool, Limonene), synthetic colorants (CI 19140, CI 42090), and preservatives such as DMDM Hydantoin and Methylisothiazolinone that may irritate sensitive scalps, and the sulfate surfactant can be drying for very dry or damaged hair.

Comparative Analysis

Positioned as a men's anti-dandruff, hair-densifying shampoo, it blends strong cleansing agents with conditioning polymers to provide both flake control and volume, a combination less common in typical anti-dandruff shampoos.
