For the primary installment, we tapped Susan C. Taylor, MD, the Bernett L.

For those who’ve ever heard a pal, coworker, podcast host, or member of Bachelor Nation swear a sure complement helped their hair develop, likelihood is it contained biotin—a vitamin that performs a key position within the manufacturing of keratin, the protein that makes up your hair and nails. However is swallowing it in capsule, powder, or gummy type actually the key to longer, thicker hair? We requested Susan C. Taylor, MD, professor of dermatology and vice chair for range, fairness, and inclusion on the College of Pennsylvania’s Perelman College of Medication, for her ideas.
“Round 50 million males and 30 million ladies in america have androgenetic alopecia, the scientific time period for male or feminine sample hair loss, so it’s no marvel everyone seems to be searching for an answer that’s so simple as taking a capsule,” Dr. Taylor tells SELF. Google “hair development dietary supplements” and also you’ll get greater than half a billion (yep, with a b) outcomes, lots of which embrace suggestions for merchandise that tout biotin as a predominant ingredient. And it is smart—in case your physique makes use of it to assist type and develop wholesome strands, the extra, the hairier, proper? However right here’s the factor: You most likely already get sufficient of it.
People largely get their fill of biotin from frequent meals like nuts, egg yolks, meat, fish, and candy potatoes, which is why a deficiency is uncommon, in response to Dr. Taylor. “The advisable day by day quantity for adults is 30 micrograms, however a typical Western weight-reduction plan accommodates greater than sufficient biotin—typically 35–70 micrograms per day,” she says. So except you’re not getting sufficient by way of meals—otherwise you have been born with biotinidase deficiency (BIOT), a situation that forestalls the physique from utilizing biotin—likelihood is you’re not operating low, she provides.
That stated, there are different issues that may affect your ranges. Lengthy-term antibiotic use might intrude with the intestine’s pure manufacturing of biotin, for instance, and heavy ingesting has been proven to lower your physique’s means to soak up it, Dr. Taylor says. Sure drugs, like anti-seizure medication and Accutane (isotretinoin), have additionally been linked with low biotin. For those who’re fearful that you simply could be poor, deliver it up together with your main care physician. They’ll ask about your signs and may order a easy blood take a look at to seek out out for certain, she provides.
The underside line: Regardless of these “scientific” assertions that drugs containing biotin work wonders, “you don’t want supplementation to assist your hair cells type and develop correctly,” Dr. Taylor says. “There are not any scientific trials supporting claims that it improves hair loss for individuals who don’t have a deficiency.” (Additionally, enjoyable reality: Taking in additional biotin than you want can mess with sure blood work–together with thyroid panels and troponin exams, which medical doctors use to diagnose coronary heart assaults—and result in false outcomes, she warns.)
So what can you do for those who’re dropping strands and freaking out? “See a board-certified dermatologist!” Dr. Taylor says. “There are numerous causes for hair loss, a few of that are irreversible, so that you don’t wish to wait and attempt to deal with it your self.” Discovering a derm is a a lot smarter technique than chewing some bizarre gummy or swallowing a capsule and crossing your fingers, she provides—these consultants are educated to evaluate all of the various kinds of hair loss and get to the, um, root of the issue.
