Is this shampoo suitable for sensitive scalps or dry hair types?

The formula is designed to control oil and includes drying surfactants, so it works best for normal to oily scalps; while it is dermatologist-tested, the presence of fragrance and DMDM Hydantoin may provoke irritation on very sensitive or dry scalps.

What is the specific role and benefit of Polyquaternium-10 in this shampoo?

Polyquaternium-10 is a conditioning polymer that coats the hair shaft, reducing static and enhancing smoothness without weighing the hair down, which helps maintain a light feel after the strong cleansing action of the surfactants.

Q: How often should the shampoo be used, and does it contain any controversial ingredients?

It can be used 2-3 times a week for oily hair, or daily if needed, but users should be aware that it contains fragrance, the preservative DMDM Hydantoin and Sodium Laureth Sulfate, ingredients that some consumers consider harsh or potentially irritating.

Product Insights

Its surfactant blend of Sodium Laureth Sulfate, Cocamidopropyl Betaine and Laureth-2 delivers an effective foaming wash, complemented by conditioning agents such as Polyquaternium-10 and soothing botanical extracts from Chondrus crispus, Spirea ulmaria and Laminaria digitata. However, the formula also includes fragrance, the preservative DMDM Hydantoin, and a high level of synthetic surfactants, which may irritate sensitive scalps or trigger reactions in fragrance-sensitive individuals.
