    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.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.

      Stopping minoxidil and finasteride for three months caused significant hair loss. The user resumed treatment with 2.5mg oral minoxidil and 0.6mg finasteride and plans to update on progress in three months.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
