These 11 Hair Growth Vitamins Actually Work (2025)

Hair thinning and excess shedding can take a massive toll on your confidence. Chances are, you’ve probably been searching for tips on how to make your hair grow faster or wondering what hair growth devices, hair growth oils, and hair vitamins or supplements are actually worth the money. Just so you know, you’re not alone on this journey—turns out, hair loss is more common than you’d think, and there are a lot of things that can cause it. Beyond genetics, which is a huge factor, damage from regular heat styling or coloring, nutritional deficiencies, hormones, and, of course, stress can all contribute to the problem.

There are still many products and techniques that can help restore your mane to its former glory, like hair growth vitamins and supplements that boost your daily nutrient intake. “Deficiencies in certain vitamins, such as zinc, iron, selenium, and biotin, can lead to shedding and hair loss,” says board-certified dermatologist Dr. Meena Singh. “So, supplements that contain these ingredients, as well as protein and vitamins A, C, D, and E, may help with hair cycling,” she adds.

Thousands of customers online rave about Nutrafol’s supplements and their impressive results. These supplements, developed by physicians, contain stress adaptogens, DHT inhibitors, and antioxidants that work in tandem to reduce stress and target other major triggers of hair thinning and loss. Sam Archer, the VP of Product Marketing & Innovation at Nutrafol, says, “At Nutrafol, we’ve developed a more customized approach to address hair thinning with multi-targeted formulas, utilizing ingredients proven to address the internal root causes directly.” In a clinical study, 84 percent of the participating women experienced less shedding after six months of using the supplement.

An ELLE editor says: “I’ve always had thick hair that grows fairly quickly, but a few years ago, I completely fried my hair with a particularly damaging round of highlights. My hair just wasn’t growing like it normally does, so I turned to Nutrafol. I couldn’t believe how well it worked to encourage hair growth, but it also helped reduce the amount of hair fall I had and made my hair feel stronger and thicker.” —Katie Berohn, ELLE beauty editor

Biotin, a kind of B vitamin, is essential for the healthy growth of hair and nails. These strawberry gummies deliver more than enough of the nutrient, leading to longer, thicker hair and nails. Plus, you only need to take two daily, so a bottle of 230 will last you over three months. They’re only a trip to the drugstore (or click, if you’re an online shopper like us) away.

An Amazon reviewer says: “I was crying so much after losing more than 50 percent of my hair because of postpartum hair loss. I could feel my scalp if I ran my hand though my hair and the breakage was horrendous. These gummies did wonders for it! They literally saved my hair (and nails). You have to be consistent, but you can start noticing the first major results in a couple months. Not only did my hair grow faster but it has gotten its thickness back.”

Grande Cosmetics may be known for its lash-growing serums, but they’re also in the business of helping our manes and skin.

“I had the unfortunate journey of having cancer at a very young age, just out of my teens,” explains Hair La Vie founder Carla Rivas. “And when you’re that young, because of the negativity in society, sometimes our vanity can take the lead.” To destigmatize the conversation around hair loss and to provide consumers with an effective supplement that would boost their confidence, Rivas developed Hair La Vie. The formula is packed with collagen, biotin, vitamin D3, and EVNol Max—an effective form of vitamin E clinically proven to promote hair growth—to make your strands grow long and strong.

A Hair La Vie reviewer says: “My hair began shedding suddenly and never seemed to ease up... I tried multiple oils and other hair vitamins. I tried Hair La Vie and within a week, I noticed way less shedding. Two weeks of consistent use and I am so impressed by how much my shedding has slowed down—especially in the shower. I will be re-purchasing every month and am excited to see what it does for new hair growth!”

A tablet a day keeps the bad hair at bay. With a promise to support hair strength, health, and growth, this supplement is packed with all the essentials—biotin, keratin, folic acid, and zinc.

An Amazon reviewer says: “My hair was falling out from over-processing and Covid. After only one week, I stopped losing chunks of hair. Baby hairs are sprouting all over. I don’t wash my hair for five days, and when I do, hardly any hair loss at all. I also pulled out too much eyebrow hair, had a bald spot, and it was filled in within a week. Olly is no joke; I’m in shock that a supplement actually delivered such extreme results and so quickly. The absolute best supplement.”

“For all-round support, I love Philip Kingsley’s Density Healthy Hair Complex, which we formulated for hair’s unique nutritional demands,” says Anabel Kingsley, consult trichologist and brand president of Philip Kingsley. She notes it contains “optimal levels” of key vitamins and minerals, such as vitamin B12, iron, vitamin D, biotin, vitamin C, and L-lysine. Plus, this formula is also suitable for those with vegan and vegetarian diets.

Key ingredients: Vitamin C, biotin, selenium

Servings: 60 tablets

Philip Kingsley rating: 5/5 stars

A Philip Kingsley reviewer says: “I’ve been using this product for a year or so and it has worked for me. My hair and nails are stronger than they have ever been. My hair was just past shoulder length when I started using it, and I’ve managed to get it half way down my back and maintain the length while keeping it looking healthy. My hairdresser said I wouldn’t have been able to get to that length without the supplements, because my hair is thin and has a tendency to become straggly when longer.”

In about three months of taking two to four of these gummies a day, you’ll see improvements in the density of your hair, the strength of your nails, and the quality of your skin. It’s no wonder, as each delicious red gummy boasts a variety of nutrients, including biotin, folic acid, zinc, and vitamins A, B, C, D, and E.

“Besides genetics, a lot of other factors—including stress, pollution, scalp imbalance, and oxidative stress from aging—can trigger hair shedding,” says Mignon. Many people who’ve had COVID-19 have also experienced hair shedding a few months after their diagnosis.

For women, “nutritional inadequacies are the most common cause of excessive daily hair shedding (telogen effluvium),” adds Kingsley. “Because hair is a non-essential tissue, it needs higher amounts of certain vitamins and minerals to function—even levels that fall towards the low-normal of blood reference ranges can cause hair loss.”

Experts agree on the benefits of hair growth vitamins. However “not every hair supplement is created equal,” says Moon Juice founder Amanda Chantal Bacon. “To ensure you get the best results with length, shine, and growth, look for a comprehensive multivitamin with bioavailable forms and clinically tested doses,” she suggests. “Also, look for additions like ashwagandha for stress relief, and targeted botanicals and micronutrients like horsetail, saw palmetto, and kelp for strength and thickness.” She notes that it is important to “pay close attention to the source and form of the ingredients and steer clear of fillers and flow agents, like magnesium stearate and titanium dioxide, which negatively affect bioavailability.”

“When taken consistently, hair growth vitamins and supplements do a great job of supporting scalp and hair health from a cellular level, promoting a healthier environment for hair growth,” adds Act+Acre founder and trichologist Helen Reavey.

“Instead of seeking out a single ingredient, look for a formula that targets hair health from various angles,” explains Chantal Bacon. “For example, a lot of people think they only need biotin for hair growth, but taking too much of one good thing can have adverse effects. Keep in mind that biotin supplements with 5,000 MCG or more can break you out and skew the results of your thyroid and vitamin D hormone panels, so seek out appropriate doses.”

Reavey also suggests looking for hair growth supplements that are “rich in plant extracts and amino acids, which work to support common nutrient deficits in the modern diet.” Additionally, “vitamins A, E, and D can help support the hair follicle, while biotin, iron, and zinc have been known to support the hair growth cycle.”

“Growing stronger, fuller hair takes time, and is sadly not something that can’t be accomplished overnight,” says Rivas. Therefore, no matter what vitamin you are taking for hair growth, consistency and patience are key. “Hair growth occurs in cycles that include a growth phase (anagen), a resting phase (telogen), and a shedding phase (catagen),” explains Reavey. “Since hair grows relatively slowly, it may take around 90 days (roughly the duration of one growth cycle) to see noticeable changes in the length, thickness, or overall health of your hair.” While formulas can vary, remember that “any supplement that boasts immediate results is not realistic,” says Chantal Bacon. “You should start to notice small shifts over time, like a reduction of shower shed and changes in texture, shine, and length.”

So, if your vitamin needs to be in the form of a tasty gummy, then definitely go for that method.

Also, don’t forget about your scalp! It deserves as much love as your strands. Try a weekly scalp treatment like the JVN Complete Pre-Wash Scalp & Hair Treatment Oil or an in-shower head massager like the Ceremonia Scalp Masajeador. By giving your scalp a little TLC and finding the perfect hair supplement, your strands will thank you.
