In what foods can i find folic acid? how much of it should i take in, so it can actually help my hair growth?

Many food sources: Folic acid would be just one of many factors that help hair growth. It would help only if that was the cause of the problem. Lowering stress, a good night sleep, sufficient 25-oh vit d3 , a healthy diet, and moving through the day would all promote hair growth.

Unproven.: There is no credible scientific evidence that Folic Acid will grow your hair. Don't believe everything you read online. That said, it's an important nutrient, and can be found in green leafy vegetables, citrus fruit, broccoli, asparagus, beans, peas, nuts, avocados, corn, carrots, and squash.
