For example, researchers in one study prescribed a biotin supplement to 22 patients with low biotin levels for hair loss following gastric sleeve surgery (6). In one study, a biotin deficiency was found in 38% of women complaining of hair loss. Of these participants, 11% had a history of deficiency risk factors, such as inflammatory bowel disease (IBD) or the use of certain medications like antibiotics (5). In an older 2012 study, women with self-perceived thinning hair were randomized to receive either a multi-ingredient hair growth supplement that contained biotin or a placebo for 6 months (4). Despite these claims, though, there’s limited evidence to suggest that supplementing with biotin or lathering it through your hair promotes hair growth in non-deficient people. "The infrared light wavelength penetrates the hair shaft and heats it evenly from the inside out," Gretchen Friese, BosleyMD trichologist, says.

However, some people — such as pregnant women and people who drink high amounts of alcohol — may develop mild deficiencies. Studies show that about a third of pregnant women in the U.S. have mild biotin deficiencies, but we need more research to understand why. "Anecdotally, I've had a few patients report that taking biotin caused an acne flare," says Colaco. Colaco says the one exception is the very few people with an actual biotin deficiency. "Studies have shown that people who fall into this category respond well to supplementation," she says. "In most other cases, there is limited evidence to show it will help you. So many dermatologists still recommend it, as there is also no evidence that it can hurt you."
Welcome the warm weather by adopting a spring-friendly hair care routine that'll leave you with luscious locks.
Believe it or not, you may be already getting a decent dose without knowing it. For now, there isn’t enough research to definitively state that biotin can help grow hair. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. It’s also worth noting that some antiepileptic drugs — like carbamazepine, primidone, phenytoin, and phenobarbital — can lower biotin levels.

Biotin is unlikely to cause adverse side effects, even in high doses. However, keep in mind that dietary supplements are not regulated the way drugs are in the United States. That means some supplement products may not contain what the label says. Biotin supplements are available in most drug stores, pharmacies, and supermarkets. Biotin supplements can be found in various oral (by mouth) forms, including liquid, tablet, gummy, and capsule forms.

Biotin supplements are known for interacting with certain diagnostic tests that use biotin-streptavidin technology, and this can lead to incorrect results (14, 15, 16).

Benefits and Side Effects of Biotin Supplements
Biotin can potentially make strands stronger and shinier, which is why those with dull, damaged locks could most benefit from using it for their hair. And despite being marketed as a "hair loss treatment," there isn't much proven scientific data to suggest that biotin supplementation can help with hair regrowth. "If you’re experiencing hair thinning or hair loss, it is best to see a hair loss specialist," advises Phipps. However, it's worth noting that making sure you're getting enough biotin in your diet can potentially help prevent thinning in the first place.

Many foods, such as fruits and vegetables, contain a small amount of biotin. Results published in 2016 suggested that biotin was a safe therapy. In some participants, a high dose taken three times daily reduced symptoms after 9 months of use. The condition appears to respond to treatment with thiamin and biotin.
At this point, there aren’t enough scientific studies that show taking a biotin supplement can help stop or reverse hair loss or make your hair grow faster. But it’s still used in many hair shampoos, conditioners, creams, and vitamins. Biotin boosts the health of the hair and nails, supports a healthy pregnancy, and helps manage blood sugar levels, among other benefits. It's also difficult to take too much of the nutrient due to its water-soluble nature. (In other words, excess amounts are simply excreted via the urine11.) But as with any supplement, it's important to check with your doctor before taking biotin.
This may be due to increased use of the vitamin, impaired absorption, or both (10). You can easily meet these recommendations by enjoying a balanced diet. In fact, it’s estimated that people living in the United States get about 35–70 mcg per day of biotin (2). Smell like a juicy apple when you wash your hair with this detoxing, cleansing shampoo. It uses a mix of citrus, spearmint, and green apple to cleanse your hair of buildup, chlorine and other impuruties for a healthy shine with added B5 vitamins and heat protection.
However, people with biotin deficiencies and those who are pregnant or breastfeeding may require biotin supplementation. If you want to make sure you’re getting enough biotin, the daily recommended biotin intake is 30 micrograms (mcg) for adults, according to the National Institute of Health. Outside of these populations, biotin supplements or biotin-added hair products are unlikely to offer any benefits (12). "I always tell my clients they need to use a good shampoo, conditioner, and hair mask - even if they use no heat at all," Friese says. Federico recommends using the R+Co DALLAS Biotin Thickening Shampoo ($38) for fine hair and the R+Co BEL AIR Smoothing Shampoo + Anti-Oxidant Complex ($34) for frizzy thick hair.
Other vitamin deficiencies may also affect the health of your hair. Beyond this, there’s no evidence to support that biotin supplements promote hair growth. As board-certified dermatologist Joshua Zeichner, MD, explains, biotin is a B complex vitamin that’s thought to be involved in hair and nail growth. You can find biotin in a wide variety of foods—from chicken, eggs, seafood, soy products, and seeds to beans, peas, lentils, and many nuts. According to Mount Sinai dermatology, biotin is needed in order to metabolize carbohydrates, fats, and amino acids, which are the building blocks of protein.
While biotin has been popular for quite some time now, it’s simply not the hair-loss cure-all that so many supplement companies make it out to be. Take it from board-certified cosmetic dermatologist Robert Finney, MD, who sees patients struggling with hair loss every single day. "If biotin is truly deficient, then it would affect all hair on the scalp, not just the hairline or part,” he adds.
