Does your hair grow painfully slowly or break all the time? You may feel like no matter what you do, you’ll never be able to get the long, luscious locks you’ve always dreamed of.

But according to leading dermatologist Melissa Piliang, healthy hair is within your reach. You just need to consume the right nutrients to get it. In particular, Piliang notes that vitamins and minerals, such as biotin, zinc, B complex, and Vitamin D, are critical for promoting hair health.

What 5 vitamins can you incorporate into your diet to promote hair growth? We explain them below:

Found in salmon, milk, mushrooms, and sun, vitamin D does more than boost energy levels. It also affects hair health. How? Vitamin D stimulates hair follicles and promotes hair growth. So it’s not surprising that research conducted at Cairo University shows that having low levels of vitamin D can cause hair loss.

You’ve probably heard that vitamin A is great for your eyes and has powerful antiaging effects. But this isn’t all vitamin A is good for. Vitamin A boosts hair health by hydrating the scalp, which keeps hair moisturized. It also helps to control levels of retinoic acid, which can cause hair loss when present in high amounts.

Known for strengthening your immune system, vitamin C also works wonders for promoting hair growth. It plays a critical role in collagen synthesis, which causes hair follicles to lengthen. It also helps the body break down iron so it’s available to promote hair growth.
