Ans. Folic acid, a form of vitamin B9, is essential for overall health and can indirectly influence hair health. It aids in cell division, including those in hair follicles, promotes proper blood circulation to deliver nutrients to follicles, and may prevent hair loss associated with folic acid deficiency. While folic acid contributes to overall well-being, its direct impact on hair growth is not as significant as some other nutrients. Maintaining a balanced diet with sufficient vitamins and minerals is crucial for healthy hair, and folic acid is just one piece of the puzzle.
