Editor's take

When someone is Biotin  deficient, biotin supplementation helps hair loss. Our tester was happy with Sports Research’s biotin pills.

“Hands down, this biotin supplement was the best I’ve ever tried. Added plus for the fact it’s vegan certified, so users who avoid gelatin can take this product! I also noticed my hair didn’t break as much in the shower or whenever I brushed my hair/ran my fingers through my hair. That made me really happy.”

— Parisa Syed, Healthline editor

While factors such as age, genetics, hormones, and medication may affect your hair, nutrition is key for hair health throughout life. In particular, vitamins B, C, and D, plus iron and zinc, play important roles in vitamins for hair growth and thickness.

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 seven high quality supplements that supply the nutrients your hair needs.

Healthline's review

Nutrafol subscription hair vitamins contain 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.

This growth nutraceutical is offered as a subscription service, affording customers the convenience of a steady supply of the product.

We also like that the company makes supplements for hair loss in both females and males, with nutrients appropriate for both. Additionally, it makes a formula specific for postpartum hair loss.

GET STARTED WITH OPTUM

Healthline's review

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 actually work to 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 thinning and shedding, though most research is based on compounds containing horsetail-derived silica, not silica itself. Horsetail can also interact with certain medications, so it’s important to consult a healthcare professional before trying this supplement.

Pros & cons

• gummy form that some people may tolerate better
• contains zinc, biotin, and several herbs that may support hair health and growth
• third-party tested
• gluten-free

• contains horsetail, which can interact with certain medications
• limited research on the effectiveness of several ingredients

Best women’s multivitamin for hair

Garden of Life mykind Organics Women's Multi Tablets

• Dose: 2 tablets per day
• Price: $$

GET STARTED WITH IHERB

Healthline's review

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. Bioavailability describes the amount of nutrients that are able to be absorbed and used by the body.

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.

Pros & cons

• contains iron, zinc, vitamin C, B vitamins, and vitamin D
• whole food-based
• third-party tested
• gluten-free, organic, and vegan

• includes rather high doses of some nutrients
• contains a proprietary blend, which people with certain food sensitivities may need to avoid

Best men’s multivitamin for hair

Ritual Essential for Men 18+ Multivitamin

4.6 (31+) from Ritual

• Price: $$$

Black Friday Sale On Now!

GET STARTED WITH RITUAL

Healthline's review

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 an effective supplement in promoting hair growth, improving hair density, and reducing hair loss in men.

Ritual subscription 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.

What our tester says

“I had been experiencing mild anemia due to a bleeding ulcer prior to taking these vitamins and the B12 and folate content seemed to help bring my hemoglobin and iron levels back closer to normal range during the 90 day test period. Capsules were soft and easily digested compared to other vitamins I’ve taken.

“A wider range of nutrients would be nice though, most multivitamins provide more than the eight this one supplies. As someone with Celiac disease, I did appreciate that these capsules were gluten free and vegan.”

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 regrowth, 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.

How to choose the best hair supplements

It’s wise to consult a healthcare professional to see which supplements are worth adding to your wellness routine.
• A doctor’s recommendations: A doctor can determine the cause of your hair loss and develop a personalized treatment plan.
