In vitro influence of light radiation on hair steroid concentrations

Highlights • Light radiation effects on hair steroid concentrations examined in three experiments. • Short-term artificial and long-term natural sunlight exposure (two months). • Consistent light-induced decrease of hair cortisol and cortisone across studies. • Increase of hair DHEA and progesterone...

Zusammenfassung:	Highlights • Light radiation effects on hair steroid concentrations examined in three experiments. • Short-term artificial and long-term natural sunlight exposure (two months). • Consistent light-induced decrease of hair cortisol and cortisone across studies. • Increase of hair DHEA and progesterone with longer natural sunlight exposure. • Questionnaire items for assessment of individual-level sunlight exposure provided. • Hair samples should be stored in a dark environment.
