    TLDR Low ferritin and cobalamin levels are better indicators of chronic hair loss in reproductive-age women than hemoglobin levels.
    The study "Hair loss from scalp among women: Does serum levels of iron, cobalamin and folic acid matter?" conducted by Sandhyalakshmi B N and Preetham Sharanappa in 2022, analyzed the deficiency status and correlation of hemoglobin, ferritin, cobalamin, and folic acid in 85 females of reproductive age experiencing hair loss. The results showed that 59.32% of the participants had anemia, 90% had lower than normal ferritin levels, and 50% had cobalamin deficiency. However, folate levels were mostly normal. The study concluded that ferritin and cobalamin levels were better indicators than hemoglobin levels alone in assessing chronic nonscarring hair loss from the scalp in females of reproductive age group.

      The user "ajsr8" shared their story of hair loss despite being on treatments. They started using finasteride in 2019 and later tried topical minoxidil, but it didn't seem to work. They also experienced side effects from other treatments. They are considering cutting off their hair and stopping the medications if there is no improvement in three months. Other users suggested trying different treatments and getting a blood test to check for underlying conditions.

      A user has been on finasteride for 6 months and feels their hair quality has worsened, experiencing more hair loss and scalp irritation. They are considering seeing a dermatologist, while others suggest the issue might be unrelated to finasteride, possibly due to deficiencies or other conditions.

Some users believe the user's hair appears stabilized, while others suggest surgery or patience, and one mentions heart issues as a reason for not using minoxidil.
