Hair fall that's gotten worse alongside IBS often points to an underlying nutrient or hormonal cause rather than a shampoo problem. Common culprits in women are low iron or
ferritin stores,
thyroid imbalance,
vitamin D deficiency, or stress related shedding, especially when digestion is also affected since poor absorption can run alongside IBS.
Next Steps
Ask for a
ferritin test specifically, not just haemoglobin, along with
thyroid and
vitamin D levels if these haven't been checked recently. Continue your current IBS treatment as prescribed, and don't start or stop anything for the hair fall on your own.
Health Tips
This kind of hair fall usually settles over a few months once the underlying cause is corrected. Please consult a dermatologist or gynaecologist to confirm which test comes back abnormal.
