In sintesi
The evidence linking folate supplementation to hair regrowth is limited and mixed — folate deficiency may contribute to hair loss in some cases, but supplementation is not well-supported as a general hair loss remedy.
- Results are mixed across 11 studies, with no clear consensus on folate's role in hair loss
- No randomized controlled trials have specifically tested folate supplementation for hair regrowth
- Folate deficiency may be more relevant when caused by medications (e.g., methotrexate) rather than diet
- Blood testing for folate levels may help determine if supplementation is appropriate
