Spend even 5 minutes—nay, 5 seconds—on social media, and there’s a great probability you’ll be bombarded with footage of influencers promoting hair-growth dietary supplements, advertisements for magical gummies promising to develop your hair quicker and longer, and doubtless even your aunt swearing by some vitamin that gave her thicker, fuller hair in a single day (and for the low, low value of a pyramid scheme!). And though I’m Cosmo’s resident skeptic—actually, I might medal in party-pooping—even I’ve discovered myself drawn to the glowing attract of hair-growth tablets.
Like, if everyone seems to be taking them, they’ve gotta do one thing, proper? And hey, what’s the hurt in downing a gummy or a cute capsule each day anyway?! (Uh, probably rather a lot, however extra on that beneath.) Since I’m clearly not the one individual having this inner disaster, I went forward and chatted with a bunch of specialists and dermatologists to search out out whether or not hair nutritional vitamins really develop your hair—and, much more vital, whether or not they’re secure to take in any respect.
Will hair dietary supplements really develop my hair quicker?
First, right here’s what hair nutritional vitamins are allegedly alleged to do: revamp your hair from the within out with a mixture of “hair-friendly” components, like biotin; folic acid; nutritional vitamins D, A, C, and E; and/or nearly the rest (!) they wish to throw in there. Dietary supplements and nutritional vitamins will not be FDA-regulated, that means manufacturers can kinda say and do no matter they need. After a couple of months of taking them, your hair is meant to look longer, more healthy, shinier, and stronger, and your scalp’s oil manufacturing can velocity up or decelerate, relying on the formulation. A minimum of, supposedly.
The factor is, these tablets aren’t backed by government-approved information, and the analysis you’ll find on them are sometimes…shady. “A lot of the studies you find in support of hair supplements are actually funded by the brands themselves,” says Dhaval G. Bhanusali, dermatologist and founding father of Hudson Dermatology and Laser Surgical procedure in New York Metropolis. Bhanusali, who makes a speciality of hair loss, says “the literature is sketchy at best, and most derms agree that supplements are not very impressive.”
And since there isn’t actually a uniform set of components, strengths, or formulations throughout manufacturers, there’s by no means going to be an official sure or no reply as as to if hair dietary supplements work (and extra problematically, which formulations can mess together with your physique). However should you ask the specialists—or me, who tried taking them for 2 months and was solely left with zits—the reply is just about an enormous ol’ NOPE throughout the board.
Do hair development nutritional vitamins work in any respect?
Okay, so regardless that nutritional vitamins themselves are completely mandatory and useful on your hair, they gained’t do a lot in case your physique is already stocked with them—which it most likely already is. “Most people get all the vitamins they need to manage their hair growth just from their diet alone,” says trichologist Dominic Burg, chief scientist at Evolis Skilled.
BUT shouldn’t I take them simply in case?! I hear you ask. Sadly, extra isn’t merrier right here. Even should you ingest triple the nutritional vitamins your physique wants (don’t), you gained’t really reap triple, and even double, the hair development rewards. “Your body keeps only the vitamins it needs and then gets rid of the rest,” says Burg. Form of like pouring water right into a glass that’s already 100% full. So until you’re really lacking some key vitamins, you’ll seemingly find yourself peeing out the surplus fairly quickly after you ingest them.
How do I do know if vitamin deficiency is affecting my hair?
“There are a lot of women running around who are deficient and don’t realize it, because of either dieting, poor nutrition, or intense stress,” says Burg. And whenever you’re tremendous careworn or not consuming sufficient, “your body will shut down your hair growth first and redirect nutrients and energy to the organs that need it most,” he says, thus leaving you vitamin poor.
And should you’ve ever skilled a extreme bout of bodily or emotional stress (hello, pandemic!), you might need seen a sudden shedding of your hair a couple of months after (or, if not, congrats! You simply found out WTF was happening together with your hair). “It’s a delayed reaction to the stress or diet that usually occurs three months later,” says Burg.
In fact, the one strategy to know for certain in case your physique is poor is to have your ranges examined by your physician, so please don’t begin popping tablets simply because your entire world is a dumpster fireplace proper now—as a substitute, anticipate a doctor to let you know that. Duh.

How can I velocity up hair development if I’m wholesome? – “multivitamins for hair growth”
“There are some studies and anecdotal evidence that support the idea that low vitamin D levels can hinder hair growth, and a lot of people tend to have low vitamin D, even if they’re otherwise healthy,” says Dr. Bhanusali, noting the identical for decrease iron ranges. “A lot of derms see good results by prescribing patients iron supplements and vitamin D supplements, although always check with your doctor before taking anything.”
If you’re not vitamin poor (which, once more, solely a physician can let you know) however nonetheless need longer, more healthy, stronger hair, then sadly, “supplements will probably do very little for you,” says Burg. Hey, possibly you’ll be the fortunate wild card—once more, there aren’t any mass research definitively saying sure or no—but when we’re talkin’ from a degree of science right here, your odds aren’t nice.
Unsure what to do? Speak to your physician. Actually. They’ll provide the thumbs up (or down) earlier than you waste your cash—or, worse, mess together with your well being.
How lengthy do hair dietary supplements take to work?
No matter whether or not you’re vitamin poor or only a wholesome one who in some way magically advantages from hair dietary supplements, you continue to gained’t see outcomes in a single day. And even in a yr. Or in 5 years. Why? “Your hair is dead, and nothing you do internally can affect its density, strength, or health,” says Burg. “Sure, vitamins will help the new hair that you’re growing, but because it grows only half an inch a month, it’ll take five or six years of taking supplements before a new strand of hair even reaches your shoulders.” Perspective, huh?
However that’s to not say you gained’t see any adjustments earlier than 2025. “If you’re vitamin deficient, supplements may help reactivate your oil glands after a few months, which can make your hair look shinier and more moisturized,” says Burg. And hey, you may even get the tiniest little bit of extra hair development, however that’s about it.
What about biotin—does it actually assist hair develop?
Sorry (once more), however there’s no definitive reply—but a ton of doubt. In accordance with dermatologist Vivian Bucay, MD, medical assistant professor on the College of Texas Well being Science Middle, should you’re taking a stand-alone biotin complement, you’d have to take at the very least 5 milligrams each day for it to have the possibility of affecting hair development—however even then, there’s no assure it’ll do something.
It’s additionally price noting that biotin—identical to any complement—isn’t with out its downsides: Extra biotin has the potential to set off breakouts in some acne-prone people (yup! Enjoyable! We’re having enjoyable!). Extra analysis is required to grasp the precise correlation, however what is understood is that taking biotin also can have an effect on main medical exams your physician could carry out. Mainly, until you your self are a physician (which, hello, why you right here?!), ensure that to debate all supplement-related information with an precise MD.
