En conclusion

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
