Olly, Thorne, and FullWell are among the best vitamins for hair growth and thickness. See what other products our nutritionists recommend.
While factors such as age, genetics, hormones, and medication may affect your hair, nutrition is key for hair health throughout life. In particular, the vitamins B, C, and D plus iron and zinc play important roles.
Some supplements are formulated with these nutrients to support hair growth, strength, and thickness. But sometimes a multivitamin or a nutrient-specific supplement will do. Here are 7 high quality supplements that supply the nutrients your hair needs.
Prices for vitamins that support hair growth may range from $0.04–$2.93 per serving, or $12.59–$88 per container.
Nutrafol’s formulation includes numerous ingredients known to support healthy hair. For example, saw palmetto may help increase hair density, and hyaluronic acid can help boost hair moisture. Vitamin C contributes to the synthesis of collagen, which contains amino acids that can be used to build keratin — an important part of hair structure.
As a subscription service, Nutrafol offers customers the convenience of a steady supply of the product.
We also like that the company makes products specific to both women’s and men’s hair health, with nutrients appropriate for both. It also makes a formula specific for postpartum hair loss.
If you are not a fan of swallowing tablets or capsules, a gummy vitamin could be a better option.
OLLY Heavenly Hair Gummies contain biotin and zinc, as well as several herbs that may support hair growth.
For example, the gummies include amla extract, or Emblica officinalis Gatertn, which when used topically, has been shown to be effective for improving hair density and growth. Oral use of amla has not been found to have the same effect.
The gummies also contain horsetail extract and silica, which may help prevent hair shedding and thinning, though research is mixed. Horsetail can also interact with certain medications, so it’s important to consult a healthcare professional before trying this supplement.
While not specifically formulated for hair growth, a multivitamin may help fill nutrient gaps in your diet, which could cause hair loss.
This women’s multivitamin contains nutrients derived from whole food ingredients, which may be more bioavailable.
It also contains specific nutrients important for healthy hair, like zinc, vitamin C, B vitamins, vitamin D, and iron.
Note that this product contains more than 100% of the Daily Value (DV) for some nutrients, which may be an excessive dose for some.
Ritual’s subscription multivitamin for men contains important nutrients for hair health, such as zinc, and vitamins B12 and D.
It also contains omega-3 docosahexaenoic acid (DHA), an omega-3 fatty acid that may be effective in promoting hair growth, improving hair density, and reducing hair loss.
Ritual vitamins are designed to fill nutrient gaps in the diet, rather than provide 100% of the DV, making it a great option for someone eating a well-balanced diet that includes nutritious foods like fruits, vegetables, and lean protein.
FullWell Prenatal Multivitamin provides a broad spectrum of vitamins and minerals that may support hair growth, including B vitamins, zinc, and vitamin D.
Designed for people who are pregnant or nursing, this prenatal product contains choline — a nutrient that other prenatal vitamins often lack — and methylfolate, which is a more absorbable form of folate.
After giving birth, many women notice extra hair shedding, which can be alarming.
Some may consider switching from a prenatal to a postnatal vitamin. This will typically contain higher doses of certain nutrients designed to support recovery postpartum, regardless of whether you choose to breastfeed.
Ritual’s subscription-based postnatal vitamin contains a variety of vitamins and minerals. It contains docosahexaenoic acid (DHA), an omega-3 fatty acid that may be effective in promoting hair growth, improving hair density, and reducing hair loss.
It also includes vitamin D, iron, and zinc, all of which have been linked to hair loss in people with these nutrient deficiencies.
Collagen is a type of protein that contains amino acids that can be used to build keratin, the protein found in hair.
Recently, collagen has become a popular supplement for healthy hair, skin, and nails. However, the research on its effectiveness for hair growth is limited.
Still, if you want to try a collagen supplement, this Thorne product is one of the best options.
Thorne Research Collagen Plus is designed to support healthy hair, skin, and nails by providing a combination of collagen peptides, plant-based antioxidants, and nicotinamide riboside — a compound that may help promote healthy aging and cellular repair.
3This product has been third-party tested by an accredited lab to ensure purity and potency.
The nutrients most often associated with supporting healthy hair growth include vitamin D, vitamin C, zinc, and iron.
Olly hair vitamins are a good gummy option for individuals who dislike swallowing pills. They contain zinc, as well as amla extract, which may support hair density and growth.
The best supplements for hair loss in women will likely contain nutrients like iron, zinc, and vitamin D that support hair growth.
For example, Nutrafol Women is our top pick for best subscription supplement for hair health. The company also makes a product specifically formulated to help with postpartum hair loss.
If you or someone you know has questions about hair loss, a helpful first step is talking with a healthcare professional to help determine what’s causing the hair loss and create a treatment plan based on your individual needs.
