A high glycerol-containing leave-on scalp care treatment to improve dandruff

Skinmed. May-Jun 2014;12(3):155-61.

Abstract

Dandruff is a common cosmetic condition associated with flaky scalp skin and pruritus. It is generally treated with regular use of antifungal-based shampoos. Research into factors underlying the characteristic skin lesions has revealed perturbations in epidermal differentiation and a dramatic deterioration in the associated process of stratum corneum (SC) maturation. These observations suggest that directly addressing the quality of the SC could have a scalp benefit. In this study, the authors investigated the efficacy of a moisturising leave-on lotion (LOL) containing a high concentration of glycerol (10%) and other known skin benefit agents (saturated fatty acid and sunflower seed oil) to reduce dandruff over an 8-week treatment period with 3 applications per week. Results of expert visual grading and biophysical measurements of SC parameters (transepidermal water loss and hydration) revealed a significant reduction in the dandruffcondition over this period, with significant improvement in both SC water barrier function and hydration. These scalp skin benefits were maintained for up to a week following cessation of the treatment. This study indicates that use of a glycerol-rich substantive LOL, designed to directly improve the quality of the SC barrier can have a significant impact on the dandruff condition.
