    TLDR Scientists found genes linked to hair length in Brangus cattle that could help breed heat-tolerant cattle.
    The study aimed to find genetic variants linked to hair length in Brangus cattle, a trait that helps with thermoregulation. Researchers genotyped 1,456 Brangus heifers and identified seven significant SNPs in the PCCA gene associated with undercoat length, which is involved in biotin transport and metabolism, where biotin deficiency can lead to hair loss. Additionally, four SNPs, including a missense mutation in the PRLR gene, were found to be significantly associated with topcoat length. The PRLR gene had a previously known SLICK mutation affecting hair length, but the association with these specific polymorphisms was novel. These genetic variants may help develop cattle with shorter hair coats that are more heat-tolerant.

      There is no natural way to stop hair loss; pharmaceuticals like minoxidil, finasteride, and RU58841 are the only effective treatments. Some users report success with minoxidil and microneedling, while others discuss the side effects of finasteride.

      Regrowing hairline without the use of Minoxidil or Finasteride, and instead using mechanical stimulation such as Derma Roller, Nizoral, Zinc Pyrithione, Scalp Massage, Scalp Exercise, Fish Oil and other topical solutions. It is cautioned that there are risks associated with not using medically-prescribed treatments, but it is suggested to consider mechanical stimulation in addition to those prescribed treatments.

      Oral minoxidil can boost hair growth but may cause side effects like heart palpitations and increased body hair. Many prefer topical minoxidil due to fewer side effects.

      The conversation discusses a user's positive experience with hair regrowth using topical finasteride, minoxidil, and microneedling after 2.5 months, noting initial shedding but improved hair density, especially at the temples, possibly eliminating the need for a hair transplant. The user is satisfied with the current treatment and is hesitant to try the experimental drug RU58841, hoping the current routine will suffice for further improvements.
