Your hair goes through a lot -- brushing, styling, cutting, washing and maybe even dye or heat. It can represent your self-expression or simply be a piece of who you are. Either way, taking good care of your hair is essential. 

We all want our hair to be as shiny and healthy as possible, but it's no secret that as we age, our hair thins. While there isn't a magical cure out there, some vitamins can help support healthy hair, skin and nails. 

Many vitamins and minerals that are already in your diet can help maintain healthy hair and help your hair grow. Studies have found that the following vitamins have contributed to promoting hair growth. These include but aren't limited to: 

The vitamin supplements for this list were selected based on price, accessibility, quality and vitamin and mineral quantities. 

Here are the best vitamins for hair growth.

Biotin, also known as vitamin B7, is a water-soluble vitamin that supports healthy hair, skin and nail growth. It is especially useful in breaking down foods such as proteins and carbohydrates, boosting energy.   

Nature Made's Biotin supplement contains 1,000 mcg of biotin. The softgels are gluten-free and contain no artificial dyes or colors. Each bottle has 120 softgels -- that's a 120-day supply. Take one daily to maintain healthy skin and hair. 

There is a note on the side of the bottle saying that biotin can interfere with some lab tests. Always consult a physician before undergoing lab work on this supplement.

Vitamins are not the end-all-be-all for all hair problems. They're not magic, and will not transform your hair overnight. However, some vitamins can help ease the thinning or brittleness of hair that comes with age or hormones. 

Keep in mind that hair loss can be due to an underlying medical condition. Always contact your doctor with your concerns before starting any type of vitamin supplement.  

Your hair needs many essential vitamins and minerals in order to grow. Luckily, a lot of those are already in your diet. If you're looking for a vitamin supplement to support healthy hair growth, find a product that contains any of the following: vitamin A, vitamin B7, vitamin C, vitamin D, vitamin E, omega-3s and zinc. 

Multivitamins are always an option, as there are many hair multivitamin products on the market. Multivitamins are best if you're looking to cover every base when it comes to your essential vitamins and minerals. 

Prenatal vitamins or prenatal multivitamins often include vitamins B12, C, D, E, iron, zinc, folic acid, calcium, thiamin and iodine. Of these, vitamin C, vitamin D, vitamin E, iron, folic acid and zinc are good for hair growth. While it's not recommended to take prenatal vitamins solely for hair purposes, prenatal vitamins do include nutrients that aid in hair growth. If considering a vitamin supplement for hair growth, look for a supplement that contains similar vitamins and minerals. Always talk with your doctor before considering prenatal vitamins.  

Nutrafol offers a product for postpartum women in the first year after birth or breastfeeding. 

Men's hair requires similar vitamins as women's hair, but the cause of hair loss and hair thinning is different in men than women. Male pattern baldness is linked to both genetic and hormone factors. Recent research has shown that vitamin D deficiencies are associated with male pattern baldness. Hair supplements for male pattern baldness often include ingredients such as soluble keratin, kelp, horsetail, root extract and antioxidants, but the research on the effect of these ingredients on hair is still being conducted.
