Grow more hair with Vitamin A: Vitamin A is often listed as an effective agent of hair growth. It is true that it can improve the health of the scalp as an antioxidant. Free radicals can certainly hasten the degradation of the follicles, especially the ones that are most susceptible to miniaturization. And antioxidants can help neutralize and counter this effect. However, it should not be assumed that it has a direct relationship on hair growth. Rather, the role of vitamins in general is to promote a healthy state of physiological balance. And this in turn optimizes the processes needed to for follicles to grow more hair.
However, lowering the dosage intake can reverse this unwanted effect.
The recommended dosage is 5,000 IU. Eating a healthy and well rounded diet in the long term is always an ideal choice. Vitamin A is found in dairy, vegetables and fish.
If you are interested in taking supplements for the sake of convenience, be sure to speak to a doctor.
