Hair loss is a significant and constantly growing social problem among both women and men. Many drugs through their toxic effects on the cells of the hair follicle matrix have an influence on mitotic divisions and the hair growth cycle, leading to anagen or telogen effluvium. Currently, there are more and more publications and clinical studies evaluating the possibility of using methotrexate in the treatment of various types of non-scarring and scarring alopecia, but there is no study of the effect relating to the hair loss with low doses of the drug in other therapeutic indications.

Alopecia impairs the physical and mental health of patients. We have previously shown that 8-week-old ob/ob mice have no reactivity to depilation, which is a stimulus that induces anagen transition in normal mice, while no hair cycle abnormalities have been reported in other studies until mice reach 7 weeks of age. Therefore, we hypothesized that ob/ob mice have abnormalities in hair cycle progression beyond 7 weeks of age. Read More
