    TLDR Higher lead and cadmium, and lower zinc and iron levels in the blood might be linked to chronic hair loss in women.
    In 2015, a case-control study involving 30 patients with chronic telogen effluvium (CTE), a common cause of hair loss in women, and 30 healthy controls was conducted to investigate the relationship between CTE and changes in lead, cadmium, zinc, and iron blood levels. The study found that patients with CTE had significantly higher blood levels of lead and cadmium and significantly lower levels of zinc and iron compared to the control group. The study concluded that changes in these metal levels could be associated with CTE, suggesting that estimating blood lead and cadmium levels could be important in cases of unexplained hair loss. The study also recommended reducing increased heavy metal body load through preventive measures and drugs, optimizing intake of calories, iron, zinc, and calcium to reduce lead and cadmium absorption, and supplementing antioxidants to reduce hair damage.

       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.

      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.

      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.
