Which Vitamins are Good for Hair Growth?

The two primary medications for combating hair loss are Rogaine and Propecia, and these can be effective for many people. However, because of side effects, it might be wise to try some vitamins for hair growth first, as many of them have been effective for many people. There are a few that stand out as potential candidates: vitamin B, zinc, lysine, and iron.

Vitamin B Complex: There is at least some evidence that the B vitamins may help facilitate hair growth, especially with B7 (biotin). Vitamin B plays a role in fat and protein metabolism, as well as carbon dioxide transfer. As a player in protein metabolism, it may also help hair grow. Many hair growth shampoos contain it, but it is not easily absorbed through the skin. Thus, taking a supplement is the way to go if you want to try it. Vitamin B is safe to take, as anything your body can’t use will just be peed out.

Zinc: There is scant evidence that zinc might help with hair growth. One study examined patients experiencing hair loss who had just had stomach stapling surgery (one of the post surgery side effects), and found that zinc supplements given to them had positive effects on hair growth. Zinc can cause toxicity if taken in to high a dose, leading to copper and iron deficiency. Keep dosage near the recommended daily allowance (15 mg in the US).

Lysine: Lyzine is an amino acid found in cereals, legumes, and fish and poultry. Essential for building proteins and cell metabolism, lysine also shows some promise as a potential hair growth vitamin. It may enhance the effects of Propecia and Rogaine, the two main hair growth medications, if taken in combination with them.

Iron: Finally, iron deficiencies can sometimes lead to hair loss, and thus supplementing with iron may help restore some hair growth. Iron overload can occur in most people, however, as deficiency is common, so you should see a doctor before taking any regular supplementation of iron.
