    TLDR Changing estrogen levels during menopause might affect genes related to body rhythms and cause increased hair loss.
    The 2016 paper "Hormones and clocks: do they disrupt the locks? Fluctuating estrogen levels during menopausal transition may influence clock genes and trigger chronic telogen effluvium" proposed a hypothesis that chronic telogen effluvium (CTE), a condition of increased, diffuse scalp hair shedding mostly in middle-aged women, may be triggered by hormonal fluctuations and alterations in circadian control genes. Despite being described almost 20 years prior, the underlying cause of CTE was not identified at the time of this paper. The authors suggested that the combination of research in hair biology and the emerging field of chronobiology could lead to significant breakthroughs in understanding CTE.

      A 35-year-old man has been using Finasteride 1mg daily for 4.5 months with no noticeable effects on hair loss, and he is considering adding Minoxidil to his treatment. Other users suggest that significant improvements may take up to 18 months and recommend additional treatments like Minoxidil, microneedling, or switching to Dutasteride.

       4 upvotes 7 years ago
      Chronic Telogen Effluvium can be managed by avoiding inflammatory foods, exercising, staying hydrated, and using supplements like krill oil, saw palmetto, or licorice root. Minoxidil is discouraged due to its cost and potential for worsening hair loss, while castor oil is recommended to strengthen hair roots and reduce shedding.

      community Could Finasteride theoretically induce chronic telogen effluvium?

      in Finasteride/Dutasteride  6 upvotes 1 year ago
      A user experienced continuous hair shedding for 13 months after starting finasteride, suspecting it might cause chronic telogen effluvium, and considered switching to dutasteride or stopping medication. Other users suggested that finasteride doesn't cause hair loss, recommending dutasteride for more aggressive hair loss, while some advised against stopping medication.

      in Progress Pictures  6 upvotes 3 weeks ago
      The user experienced chronic telogen effluvium and mild male pattern baldness, treated with finasteride, oral minoxidil, and later switched to dutasteride, which stopped excessive hair shedding. Other treatments like low-level laser therapy, hair loss shampoos (except ketoconazole), and supplements were ineffective.
