TLDR Hair loss patterns differ between males and females due to 5 master regulators and JAK-STAT signaling affects hair growth.
The study aimed to understand the differences in hair loss patterns between males and females and the susceptibility to androgens in certain regions of the scalp. The researchers identified 5 master regulators that mediate molecular differences in skin scalp samples by gender. The study found that some of the top 10 genes differentially expressed in sex-segregated cohorts are associated with mesenchymal components differentiation, suggesting inherent differences in the skin. The authors also found that JAK-STAT signaling promotes hair growth and that inhibiting this pathway can rapidly initiate anagen.
