    TLDR The KRTAP21-2 gene affects wool length and quality in sheep.
    The study investigated the ovine Keratin-Associated Protein 21-2 (KRTAP21-2) gene in 389 Merino × Southdown-cross lambs, identifying five variants (A-E) and their association with wool traits. Notably, sheep with genotype AC had a 12.5% greater mean staple length (MSL) compared to those with genotype CE. Variant E was linked to lower MSL and higher fiber diameter standard deviation (FDSD), mean fiber diameter (MFD), and prickle factor (PF). The findings suggested that KRTAP21-2 could be a potential gene-marker for improving wool traits, emphasizing the genetic influence on wool characteristics and the potential for selective breeding.

      The user experienced hair thickening and reduced shedding using minoxidil, finasteride, and dutasteride, with a switch from finasteride to dutasteride due to ineffectiveness. They also use a saw palmetto shampoo and take vitamin D3 supplements, while considering potential underlying causes like vitamin deficiencies and hard water buildup.
