    TLDR Metabolites and diet affect hair growth cycles in cashmere goats.
    This study used targeted metabolomics to analyze 1,903 metabolites in the skin of 12 female Jiangnan cashmere goats during different hair follicle cycle stages (anagen, catagen, and telogen) and feeding modes (grazing and barn feeding). The results showed that most metabolites, including amino acids, nucleotides, and lipids, were downregulated from anagen to telogen, indicating active cell processes in anagen and apoptosis in the transition to telogen. Key metabolites like 2’-deoxyadenosine and riboflavin were identified as potential regulators of the hair follicle cycle. The study also found that feeding practices influenced metabolite expression, suggesting that diet can affect hair follicle growth. External factors like light and temperature were shown to impact metabolite levels, further affecting hair growth.

      A user reported losing hair after 7 months of using oral minoxidil, finasteride, and dutasteride, but others reassured that this is likely just a shedding phase where old hairs fall out to make way for new growth. Some users experience sheds every 7-8 months and suggest staying consistent with treatment.

      A user is experiencing significant hair shedding after starting a treatment regimen of 1mg oral finasteride, 3mg oral minoxidil, 2.5mg biotin, and vitamins. Despite the shedding, they remain optimistic and plan to continue the treatment for a year before making any conclusions.
