Drastic hair fall in a woman is usually driven by something treatable rather than the hair itself, commonly
thyroid issues, low iron stores, low
vitamin D, PCOS or high androgens, or stress after a crash diet or a tough few months. The shedding is a downstream effect, not the root cause.
Next Steps
Since you already have a blood report, check specifically for
ferritin, not just haemoglobin, along with
thyroid and
vitamin D, and ask about PCOS if your periods are irregular. Fixing whichever cause is low usually settles the shedding over several months.
Health Tips
Please consult a dermatologist or gynaecologist in person with this report rather than self-treating with supplements, since the right fix depends on what's actually low.
