11 Vitamins That Actually Will Give You Healthier Hair, Skin, And Nails, Say Experts

Aside from the fact that it tastes delicious, this vitamin contains keratin, biotin, and vitamin C, all of which are known ingredients for healthy hair, skin, and nail growth. Additionally, it features vitamins A & E, manganese, selenium, and zinc, which, according to dermatologist Dr. Azza Halim, M.D., are "all necessary for collagen production, fat and protein metabolism as well as antioxidant benefits."

Rave review: "These vitamins really helped to improve the overall quality and appearance if skin. My skin felt firmer and more supple. I also noticed a difference in my hair as well."

This clinically tested supplement combines biotin with botanicals like vitamin E, ashwagandha, biocurcumin, keratin, and resveratrol to rebalance the stress hormones that can cause hair loss, combat the inflammation that interrupts hair growth, and fight free-radical damage, says New York City dermatologist Dendy Engelman, M.D.

In essence, it both addresses some of the biggest causes of hair loss while making the hair that grows stronger and healthier. However, if you have hair loss because of an active disease or cancer treatment, Nutrafol won't help you there. And you shouldn't take it if you are pregnant or breastfeeding.

Rave review: "My main area of concern was thinning hair, especially around my hairline. I have definitely seen a huge improvement. My hairline has filled in completely, I barely have any shedding now, and my hair feels healthier, is less brittle and dry, and has more volume."

Another supplement that combines biotin with vitamins and minerals, Viviscal looks to iron, vitamin C, niacin, and zinc for clinically tested additions that are shown to support the growth of fuller, shinier hair, as well as stronger nails, says Deanne Mraz Robinson, M.D., assistant clinical professor of dermatology at Yale New Haven Hospital. It's a comparable (but more affordable) alternative to Nutrafol and similarly helps promote healthier hair growth.

Rave review: "I have been using this for about 6 months. I started losing a lot of hair due to stress. It works amazingly well. My bald spots have started filling in. I even noticed that my eyebrows are growing in. I have been using this for about 6 months but started to notice the difference in 3 months."

Alongside nutrients like collagen and keratin, which are essential for the health of hair, skin, and nails, these vitamins also contain hyaluronic acid to promote skin hydration.

Rave review: "After a few weeks my skin is hydrated, and I’ve noticed significantly less shedding when I brush my hair after I shower. I’ve also noticed a bunch of baby hairs growing, and my lashes are longer than ever. Highly recommend these vitamins."

If you want to fight weakened hair, skin, and nails all at the same time, cystine is your MVP. This amino acid helps build the fibrous protein known as keratin that is crucial to strengthening the structure of all three, says Jaliman.

It’s also unique in that it creates disulfide bonds, which aid in retaining moisture and keeping keratin together (translation: you'll notice less dryness, too). Cystine also helps your body metabolize biotin, meaning it'll be better equipped to convert your food into energy and nutrients.

Rave review: "I had hair loss post-Covid and could not get it to stop. My sister told me to order this and it worked right away."

Are your hair, skin, and nails feeling super dry and brittle? Vitamin A can come to the rescue, since cells use this essential vitamin to produce the oil that keeps areas like the scalp and skin moisturized, says Engleman, while also stimulating fibroblasts (skin tissue cells) that help keep the complexion firm and healthy.

Other vitamin A benefits include better vision, a stronger immune system, and reduced risk of heart disease.

Rave review: "All I can say is, 'Wow!' I've been taking this for a week and i can tell a HUGE difference in my skin. I've been struggling with hormonal cystic acne for the past three years and have tried so many regimens. After only a week of taking this, I can notice a huge change in the texture of my skin. My skin feels tighter and brighter."

This multivitamin created specifically with women 18 and older in mind was formulated with nine nutrients, including folate (the active form of folic acid, which is known for promoting healthy hair growth), vitamin E (which can repair damaged skin), and vitamin B12 (which can reduce the appearance of dull skin).

Rave review: "I have been taking these for a few months and I love them! They are everything I want in one pill and they don’t taste gross due to the fish oil thanks to the mint flavor. They are also time release so you get more from your pills."

This rejuvenating multivitamin includes vitamins A, C, E, folate, B6, B12, and more, but it also contains organic sulfur. "Organic sulfur provides the body with natural building blocks for healthy hair growth," Sacramento-based board-certified dermatologist Dr. Oma Agbai, M.D. says.

Rave review: "All I can tell is that within two weeks of taking Maxi Hair, I saw a definite, striking change in my hair loss. I have very few hair in my tub after shampooing and barely any hair on the floor after brushing. I don't see yet much difference in the thickness of my hair but again it has been a month so the new hair is still short."

It may be vegan, but that doesn't effect efficacy at all. These all-natural capsules contain more than 1,000 times the daily recommended value of biotin. Why is that so great for your hair, skin, and nails? Biotin boosts keratin production—vital for health and growth, says Manish Shah, MD, a board-certified plastic surgeon in Denver.

Rave review: "I have tried at least 5 brands of hair vitamins. None worked as well as Shedavi! I get my hair cut every 6 weeks and this last time I went my hairdresser could not believe how much my hair had grown and she said it felt thicker. So that was enough for me; I ordered my second bottle."

Dr. Daniel Yadegar developed this supplement in response to his sister's struggle with hair loss, skin issues, and weak nails. The unique combination of betaine HCL, saw palmetto, MSM, and biotin is specially designed to enhance collagen production to both thicken and strengthen hair and nails. The vegan and cruelty-free formula also works hard to balance hormones.

Rave review: "I started taking this after I went from blonde back to my natural brunette color. It's been 3 months and my hair is healthier than ever, less breakage and shedding and super shiny! The first thing I noticed within 2 weeks were my nails, they grew like crazy and became so hard! My nails have never been this strong!"
