    TLDR Proteomic analysis can identify genetic differences in mouse hair, helping understand hair defects and variations.
    The study used proteomic analysis to investigate differences in pelage hair among three mouse strains: AKR/J-hid/hid, FVB/NJ+/+, and LP/J+/+. It identified 111 proteins in AKR/J-hid/hid mice, highlighting deficiencies in cortical cell projections and lower trichohyalin levels, which may contribute to their hair defect. Significant differences in 65 proteins were found across the strains, with AKR/J mice showing unique proteins not present in others. The research demonstrated the utility of proteomic analysis in distinguishing genetic variations in hair structure and provided insights into the molecular basis of hair defects, suggesting potential applications for understanding human hair variations.

      The user "Top_Replacement_7777" shared their positive results with finasteride for hair loss. They asked about maintaining their hair with finasteride and the impact of vaping on hair growth. Another user reassured them that vaping wouldn't affect their progress.

      A new hair loss protocol using FDA-approved topical treatments targets eight pathways, potentially improving results by 60-75% compared to the standard 40-50% from oral minoxidil and finasteride. The protocol includes minoxidil, finasteride, tacrolimus, cetirizine, bimatoprost, lithium gluconate, losartan, melatonin, NAC, caffeine, and tretinoin, with a monthly cost of $35-50 in Mexico and $80-150 in the US.

      The conversation discusses a hair loss and scalp care routine involving ciclopirox shampoo, benzoyl peroxide, clindamycin gel, clobetasol propionate, and calcipotriol to manage seborrheic dermatitis, folliculitis, and inflammation. It also touches on the role of diet and other treatments like oral minoxidil and pioglitazone for scalp health.
