    TLDR Nano-ZnO on skin may hinder hair growth by affecting stem cells.
    The study investigated the effects of cutaneously applied nano-ZnO on hair follicle stem cells. It was found that nano-ZnO reduced the ability of these stem cells to differentiate. This suggests that exposure to nano-ZnO could potentially impact hair growth by impairing the differentiation process of hair follicle stem cells. The research provided insights into the potential risks associated with the use of nano-ZnO in products that come into contact with the skin, highlighting the need for further investigation into its safety and effects on hair follicle biology.
