If you’ve ever experienced any hair thinning or shedding, there’s a good chance that you’ve searched for the best hair growth vitamins or supplements to come to the rescue. Hair loss is extremely common and can be the result of many different factors, from genetics to dryness caused by high-heat styling or the environment. Even nutritional inadequacies in your diet, stress, or hormone fluctuations may be to blame, which is why many new moms experience hair shedding during the postpartum phase.
Although some amount of regular shedding is normal, if you notice that you’re losing more strands than usual, it’s best to consult your doctor and discuss the best course of action. Luckily, there are a multitude of over-the-counter options, including hair growth oils and shampoos, high-tech hair growth devices, and hair growth vitamins that work to help reduce thinning and encourage hair growth.
According to dermatologist Dr. Meena Singh, there are many vitamins that can help boost your strands. “Deficiencies in certain vitamins such as zinc, iron, selenium, and biotin can lead to shedding and hair loss,” says Singh. “So, supplements that contain these ingredients, as well as protein and vitamins A, C, D, and E may help with hair cycling.”

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.”
What causes excessive hair shedding or thinning?
“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 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.”
What exactly do hair growth vitamins do?
Ingredients and vitamins such as biotin and vitamins C, E, and B1 “can prolong the anagen (growth phase) of the hair cycle and decrease the percentage of hairs in the shedding phase,” explains Singh. Biotin is also great for hair growth, as it promotes keratin production and can cause your strands to grow faster. Plus, it promotes healthy skin and nails. Double whammy!
Do hair growth vitamins actually work?
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, “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, in turn promoting a healthier environment for hair growth,” adds Act+Acre founder and trichologist Helen Reavey.
How should people choose the best hair growth vitamins?
“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.”
What else should I know about hair growth vitamins?
“Growing stronger, fuller hair takes time and it’s 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 (which is 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 out 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. Trust us, by giving your scalp a little TLC and finding the perfect hair supplement, your strands will thank you.
