Folic acid aids in tissue growth and cell function, including skin, hair, nails and organs. Operating at the level of cell division, it helps to form red blood cells and to produce DNA. Folic acid creates healthy hair DNA, which improves hair quality and helps it grow faster. Folic acid has been clinically proven to treat certain types of hair loss, including alopecia.
You can obtain plenty of folic acid from your diet by eating foods such as beans, citrus fruits or spinach.
