Isizathu se-seborrheic alopecia sivela kwimisebenzi egqithileyo yamadlala asabisayo. Ezi ndlala zonyusa umsebenzi wazo ngokubola kwehomoni okanye ngomsebenzi we-enzyme eyaziwa ngokuba yi-5alpha-reductase. Le enzyme yiyo eguqula i-testosterone ibe yi-dihydrotestosterone. Inani lee-enzymes ezinoxanduva lokuguqula enye ibe yenye kunye nenani lezamkeli zokubamba ii-androgens ezikhoyo kwi-scalp ziyahluka.
