الخلاصة
There is limited evidence connecting folate to telogen effluvium — while low folate levels have been observed in some patients, research does not yet support folate supplementation as a reliable approach for this condition.
- Mixed results across 6 studies — no consistent pattern linking folate levels to telogen effluvium
- All studies are observational; no randomized controlled trials exist for this specific use
- Folate is one of many micronutrients that may play a supporting role in hair health
- A comprehensive nutritional assessment may be more useful than supplementing folate alone
