Is L'Oreal Professionnel Serioxyl GlucoBoost suitable for sensitive or dry scalp?

The shampoo is designed for oily or buildup‑prone hair and uses strong surfactants, so while it effectively removes excess oil, it may be too drying or irritating for very sensitive or dry scalps; those users should limit use to once or twice a week or choose a milder alternative.

What does salicylic acid do in this clarifying shampoo?

Salicylic acid is a beta‑hydroxy acid that helps dissolve dead skin cells and sebum, break down dandruff flakes, and unclog hair follicles, providing a deep‑cleaning effect and supporting scalp health.

How often should the shampoo be used and are there any controversial ingredients to be aware of?

It is recommended to use the shampoo 1–2 times per week for typical hair; the formula contains sodium laureth sulfate, sodium lauryl sulfate and synthetic fragrance, which some consumers consider controversial due to irritation potential, and it also includes the synthetic dye Blue 1.
