Before making a purchase, learn about the link between biotin and hair growth and if there is scientific evidence that biotin supplements are effective in treating hair loss. But for optimal hair benefits, consider a supplement with complementary nutrients. One hair-healthy ingredient to look for is vitamin D3, a fat-soluble vitamin that's required for healthy hair follicle function. Of vitamin D from their daily diet, and clinical vitamin D insufficiency persists in almost half of the population (41%14, to be exact). Taking a supplement can help you obtain adequate levels, as there are only a few foods that naturally offer vitamin D. There is no firm scientific evidence to support the use of biotin supplements to improve hair growth unless a person has a specific biotin deficiency.

First, you may consider working some biotin-rich foods into your diet. And you may already have some items in your pantry or fridge that fit the bill. But biotin has been shown to help with preventing balding and hair loss. Anything that disrupts your gastrointestinal (GI) tract can also affect hair growth, she adds.

In a 2019 review, researchers found that men with MAA had slightly lower levels of biotin than those with no hair loss. However, the difference wasn’t significant enough to indicate a direct link between biotin and MAA (11). Biotin is found in many foods, such as egg yolks, liver, cauliflower, mushrooms, soybeans, beans, lentils, almonds, nuts, and whole grains. It’s also widely available in supplement form, either by itself or combined with other vitamins and minerals (3, 4). Hair loss and balding isn’t just a male problem, but that doesn’t make the reality of it any less stressful for women. And the more you stress about hair loss, the more likely it is that the increase in cortisol will cause even more hair shedding.
Biotin-rich foods
There’s no doubt that Biotin is the most popular skin, nails, and hair supplement on the market today. It is praised and recommended among beauty queens, celebrities, and everyone in between. This review will highlight all the benefits of Vitamin B7 as well as some secrets many do not know. Many manufacturers of cosmetics claim that biotin supplements may improve the strength and durability of fingernails and enhance hair and skin health.
Special Health Reports
It's important to consult your doctor before taking a biotin supplement to determine what dosage is best for you. Biotin plays an important role in converting carbohydrates, fats and proteins into energy. Topically, Gross suggests using the ingredient minoxidil, widely known by the brand name Rogaine. "It is particularly helpful in stopping the progression of hair loss, which, in my opinion, is the most common benefit," he says. That's due largely in part to the recommended daily amount (RDA) of biotin. According to Bhanusali, it depends on the source you're getting the RDA from, but typically between 30 and 100 micrograms — not milligrams — a day is sufficient.
What’s the recommended dosage/intake for Biotin?
Biotin has become a popular supplement that is widely advertised to support hair growth. In the world of beauty supplements, biotin is treated as the magic fix—like the beauty equivalent of restarting your phone. You hear about it so often that you probably don’t even think to question it. When choosing a supplement, look for third-party tested products and consult a healthcare provider, registered dietitian nutritionist (RD or RDN), or pharmacist.
About the Reviewer
It stated that samples from people who had consumed high levels of biotin through supplements could provide “clinically significant incorrect” laboratory results. However, people with biotin deficiencies and those who are pregnant or breastfeeding may require biotin supplementation. It is rare for a person to have a biotin deficiency, and most people in the U.S. naturally get enough from gastrointestinal bacteria and a balanced diet. Like all B vitamins, biotin helps to metabolize carbohydrates, fats, and amino acids, which are the building blocks of protein. Biotin may be beneficial for certain types of hair loss, such as hair loss due to biotin deficiency or conditions that affect biotin metabolism.

Health benefits
Ongoing studies contribute to the overall understanding and acceptance of biotin as a valuable component of hair care. Biotin is not a magical solution for hair growth and may not work for everyone. Consult a healthcare professional if you suspect an allergic reaction. Biotin nourishes the scalp, enhancing the overall health of hair follicles and reducing scalp issues. If you take any of these, talk to your doctor or a dietitian to ensure you’re getting enough biotin, either through your diet, with a supplement, or a combination. Eggs are a good source of biotin, but avoid consuming them raw to get the most of the vitamin.
vitamin D
Extensive scientific research has been conducted to understand the benefits and mechanisms of biotin for hair growth. Its role in promoting hair growth and overall hair health was gradually recognized over time. Biotin supports hair growth and strength, while collagen contributes to hair elasticity and overall hair health. Biotin primarily focuses on promoting hair growth and strengthening the hair shaft, while collagen plays a role in overall hair health and elasticity. Those who are pregnant and breastfeeding can also develop low biotin levels despite normal dietary intake of the vitamin. This may be due to increased use of the vitamin, impaired absorption, or both (10).
The most important step is to test your serum before using it for the first time. “Apply the serum to a small spot on the scalp for a few days to ensure that there is no irritation before applying it more broadly,” says Dr. Mirmirani. “A measured approach is best.” To that end, get comfortable with the fact that you’ll need to be both consistent and patient in your usage, as the results can take time. I’ve spent the last 8 years of my life reading, researching, and helping people with thyroid problems, hormone imbalances, and weight loss resistance. Through my articles, videos, and supplements, I’ve been fortunate enough to help thousands of people take control of their weight, thyroid, and hormones.
Massage this serum into your scalp for minutes and rinse before applying your go-to shampoo and conditioner. When it comes to your hair care routine, it's probably stocked must-haves like sulfate-free shampoos, hydrating conditioners, and heat-protectant sprays, but what about hair oils? TBH, hair oils are an underrated haircare staple that can treat your concerns like an itchy scalp, help soften your strands, and improve the overall health of your hair and scalp. From castor oil to argan and rosemary, there are so many different hair oils to choose from. Seventeen tapped three experts to break down which are the best oils for your hair type and how to use them. Among them are endocrine disorders, which include problems with your pituitary, parathyroid or adrenal glands, or your ovaries or testes.
Also, consider avoiding formulations that contain additives that might irritating to the scalp and inadvertently cause dryness or itchiness, such as harsh chemicals, dyes, and fragrances. Instead, seek out those that have been dermatologist-tested, says Dr. Shaver. This content is strictly the opinion of Dr. Westin Childs and is for educational and information purposes only.

Further, the study was small, and it’s possible that the participants were deficient in one or more nutrients present in the supplement that affect hair health. Any such deficiency could have been corrected through the study period, resulting in hair growth. However, because the hair growth supplement contained multiple ingredients — including zinc and iron, which are also necessary for hair growth — it’s not possible to attribute the study’s findings to biotin alone. This article explains the link between biotin and hair health and whether the vitamin is effective and safe for hair growth or preventing hair loss. Before you add hair oil to your online cart or snag one off the shelves in-store, it's important to consider what your hair needs first. You're probably all too familiar with coconut, argan, rosemary, and tea tree oils, but they all meet a different need.
“For sensitive or acne-prone skin, either frequent pillowcase changes or wearing a hair bonnet after serum application may be helpful,” she says. Beyond iron (and ferritin), you also need adequate levels of biotin, B vitamins, amino acids, and other minerals (6) (selenium and zinc) in order for hair growth. Though sales are skyrocketing, only limited research supports taking biotin supplements for hair growth — especially in men. In addition, the supplement contained other nutrients known for promoting hair growth like amino acids, zinc, and vitamin C, so it’s unclear if biotin affected the results (13). Biotin levels that are too low can lead to poor hair growth and hair loss. However, considering that most people have adequate levels, adding more to your diet through supplements likely won’t help (7).
The majority of participants either were known to have a biotin deficiency or had a history of poor hair and nail growth that indicated other underlying issues. To combat this, health and wellness gurus have touted the benefits of biotin not only for nail growth but also for hair health. Biotin promotes hair growth primarily on the scalp by supporting the health of hair follicles. No, there is no scientific evidence to suggest that biotin causes hair growth on the face. Many individuals are seeking natural solutions to promote hair growth, and biotin has gained recognition as an effective option. This research has helped establish biotin's importance in hair care and led to its inclusion in many hair growth products.
