TLDR Selenium disulphide detergents increase hair oiliness by boosting some lipids and reducing fatty acids.
The study investigated the effects of two selenium disulphide-containing detergents on the refatting rate of human hair. Both detergents, one with a hard base and the other with a soft base, led to a significant increase in triglyceride levels (∼160%), wax esters (∼30%), and squalene (∼20%), while fatty acids decreased by ∼20%. Cholesterol and polar lipid levels remained unchanged. These results suggest increased sebum production and reduced lipolytic activity in the scalp, with no significant differences observed between the effects of the two detergents.
