This shampoo acts directly on oily scalps prone to dandruff, helping to reduce flaking and regulate sebum production. It is intended for users with persistent or recurring oily dandruff, offering visible results from the first applications. Its formula combines keratolytic and sebum-regulating active ingredients that promote a clean, less irritated and more balanced scalp. With regular use, it contributes to lighter, looser and healthier-looking hair, while protecting the sensitive skin of the scalp and reducing the recurrence of flaking. Who it is suitable for: - Regular users of Ducray Kelual Squanorm shampoo who wish to continue treatment in a more economical and ecological way. - Those who already have an empty bottle of shampoo at home and simply want to refill it. - People with oily scalps and persistent dandruff looking for a lasting solution.
