    TLDR Higher expression of the keratin-associated protein 8.1 gene in Liaoning cashmere goats is linked to finer cashmere fibers.
    The study used Real-time PCR to measure the expression of the keratin associated protein 8.1 gene in the skin and hair follicles of Liaoning cashmere goats, comparing it to three varieties of Ovis aries. Results indicated that Liaoning cashmere goats exhibited higher gene expression than the hybrids, correlating with finer cashmere fiber. The expression was up-regulated by 1.2 times, suggesting that higher expression of this gene was associated with thinner cashmere fibers, indicating its potential role in regulating cashmere fineness.

      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.
