It has been observed that dandruff develops more easily in the excessive presence of sebum and is more 0002 1. Field of the Invention readily pruritic. Sebum secretion is a normal phenomenon 0003. The present invention aims principally to propose a which is useful for the skin and for the head of hair. Sebum new active agent for the prevention and/or treatment of scalp protects the scalp and gives the haira sheen by lubricating the disorders, especially aesthetic disorders. In particular, the cuticle. However, hypersecretion of sebum, or seborrhoea, present invention relates to dandruff disorders of the scalp, in may lead to disruptions, annoyances, sensations or feelings of particular of a greasy scalp. The present invention is also discomfort, aesthetic disorders, or even a skin pathology. directed towards proposing a novel cosmetic process for pre Thus, an excessive secretion of sebum promotes the appear venting and/or treating a dandruff condition of the scalp.

The scalp is an epidermis that undergoes continual tions in sensitive individuals, i.e. individuals having an renewal, like the rest of the cutaneous tissue, and that is rich impaired barrier function, and therefore more particularly in Sebaceous glands. Normally, the scalp is renewed by susceptible to the destructive action of fatty acids on the imperceptible, non-visible elimination of the superficial skin cutaneous barrier. cells. However, excessive renewal of the cells of the stratum 0013 Thus, the greater the presence of sebum, the more corneum of the scalp, for various reasons, may result in the readily oily dandruff develops. Moreover, it has a tendency to formation of large, thick patches of cells which are visible to be more readily pruritic. the naked eye, known as "dandruff. 0006 Various factors may promote the onset of dandruff. 0014 Dandruff conditions generally respond to various For example, mention may be made of stress, the winter local or systemic treatments. For example, various prepara period, an excess of sebum, a hydration defect or colonization tions comprising antimicrobial agents or keratolytic agents or of the skin or of the hair follicles by yeasts of the Malassezia keratinization regulators are commonly proposed for treating spp. type. These factors especially have the common feature dandruff conditions. In particular, preparations combining of causing or promoting skin inflammation.
