Looking to reduce hair shedding or strengthen your hair? Here are the best vitamins for hair and what the evidence says, so you do not spend more than you need to.
Do vitamins work for hair?
The honest answer is that they mainly work when there is a deficiency. If your iron, zinc or vitamin D levels are normal, taking more does not significantly speed growth or stop hair loss.
The best vitamins and minerals for hair
- Biotin (B7): involved in keratin synthesis; useful mainly when there is a deficiency (which is uncommon).
- Zinc: contributes to maintaining hair and preventing premature hair loss.
- Iron: iron deficiency is the most common nutritional cause of hair loss in women.
- Vitamin D: linked to the hair-follicle cycle.
The biotin myth
Biotin is sold as a miracle solution, but without a deficiency its effect is limited. At high doses it can also affect blood-test results: review biotin contraindications. You can meet your needs through diet: see foods rich in biotin.
How to choose and when to seek advice
Ideally, start with blood tests and supplement only what is lacking. If hair loss is intense or sudden, consult a healthcare professional or dermatologist. If you also feel low in energy, see which vitamins to take for tiredness.
