Biotin Vitamin B7 The Nutrition Source Harvard T H. Chan School of Public Health

They've linked a shortage of the vitamin to dermatitis, acne scarring, and other skin problems, but they need to do more research into how biotin levels affect your skin. About half of pregnant women in the United States have a mild biotin deficiency. This article looks at why people need biotin, the recommended intake, sources, and any possible health risks. If you’re unable to get enough biotin naturally, a supplement may be suggested by your doctor.

While symptomatic biotin deficiency is rare, low biotin levels are common during pregnancy. Research suggests that taking biotin supplements, even in high doses, has very little risk. "Smoking causes inflammation throughout the body, which makes so many things worse, and hair loss is no exception," says Colaco. "Eating too few calories or not getting enough nutrients like iron or protein every day can cause hair loss as well." Samolitis breaks down one condition, telogen effluvium, which causes you to lose more hair than normal, but typically it remedies itself. You may take a biotin supplement to help with regrowth or length and attribute any growth to the biotin, when it may have nothing to do with the growth.

Clinical trials have found evidence that biotin supplementation can improve these conditions and your nails' firmness, hardness, and thickness. 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. Though sales are skyrocketing, only limited research supports taking biotin supplements for hair growth — especially in men. Besides this review, there appear to be no clinical studies on biotin supplements and male hair thinning, though there are some studies in women (12). 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).

Biotin helps in the production of keratin, a protein that makes up your hair, skin, and nails. Because of this, many companies tout biotin for its ability to help with hair growth, but there is very little research on the relationship between the two. A study published in 2015 found that women with thinning hair experienced some reduction in shedding after taking an oral marine protein supplement for 90 days.

Talk with a dermatologist if you notice signs of unhealthy hair or scalp, including excessive hair loss. Enriched with biotin and collagen, this volumizing shampoo from Renpure can help keep your locks hydrated. B-complex vitamins, amino acids, and proteins work together to increase strength and thickness for beautiful shine and body.

This process is important for maintaining healthy skin, and it may be impaired in people with low levels of biotin. However, little research has linked the vitamin with hair health in people who do not have biotin deficiencies. For people with this deficiency, taking supplements that contain biotin could improve the strength of their nails.

The RDA is the average daily nutrient intake level needed to meet the requirements of 97-98% of healthy adults. Like all B vitamins, biotin helps to metabolize carbohydrates, fats, and amino acids, which are the building blocks of protein. Maintaining your hair’s strength and volume may require using a biotin shampoo. You might have to try a few before you find what works best for you. Remember that there isn’t enough research to prove that biotin supports hair regrowth.

For this reason, there is no recommended daily allowance for biotin. Adults need 30 micrograms of biotin each day to avoid a deficiency. Among the most common complaints people have when it comes to these more aesthetic parts of our bodies are brittle nails and thinning hair. This gentle shampoo is sulfate-free and formulated with biotin, rosemary oil, and castor oil to promote healthier, fuller, more hydrated hair. It’s gentle enough to be used every day on all hair types and textures, and it won’t weigh down your hair.

Indulge in this luxurious shampoo that adds intense amounts of moisture with each wash, all while fighting frizz and maintaining a natural curl pattern. It'll leave your hair silky smooth, thick and hydrated, ready for you to style. If you've been spending a lot of time with the blow dryer over the winter, it's a good idea to part with it and try something a little different. After all, humidity and frizz can destroy a great look in minutes. Your hair also needs to take some time to get used to the changing temperatures, so don't scorch it even further by applying heat when it isn't needed.

Hair supplements promising "longer, stronger" hair often contain more than the typical RDA of biotin. But having an excess of biotin doesn't necessarily provide hair with the benefits you may be seeking. Bhanusali, Samolitis, and board-certified dermatologist Shanthi Colaco all say that biotin is water-soluble, meaning what your body doesn't use, you urinate out. Although high doses are unnecessary, it's considered harmless if you take more than the RDA.

In fact, Vitamin E is a great hair growth vitamin as well all on its own. Like the others, Difeel also has other biotin products, such as shampoo, conditioner, and a dozen or so other oils. Unfortunately, you will find many serums and liquid biotin supplements if you look for biotin oil. Worth noting is that biotin oil is not quite the same as liquid biotin. Liquid biotin is a biotin supplement that you take with a dropper.

Laboratory tests that measure certain hormones in your blood can give false results when there is extra biotin there. Using biotin oil on your hair can be done almost any way you wish to. Therefore, applying it to your hair in a hair mask or some similar thing not long before washing your hair works. It is very inexpensive, comes with actual instructions – not many biotin oils do – and has one or two other ingredients that help it not make your hair too oily.

Otherwise, your body might decide that the biotin is better used elsewhere. Legumes high in protein, fibre, and minerals include peas, beans, and lentils. Peanuts and soybeans are two of the category’s highest sources of biotin. Legumes are usually cooked and then added to baked dishes or stir-fries, or they can be the foundation of salads, meals, and curries. Excess intake of this vitamin has also been linked to the measurement of false troponin levels — used to indicate heart attacks — leading to delayed treatment and even death (14, 15, 16).

However, while a person may get an upset stomach, there is no evidence to suggest these high doses are dangerous. According to the National Institutes of Health, the average person in a western population consumes 35–70 mcg of biotin daily from foods they eat. For most people, a supplement will not be necessary as long as they are eating a healthy, varied diet.

You don't use infrared hair tools any differently than other heat-styling tools. However, it's important to note that infrared hair tools aren't completely heat-free, so you should always use a heat-protectant when styling your hair. Our current favorite is the Dry Bar Hot Toddy Heat Protectant Mist Coconut Colada Scent ($29). Some of these enzymes are involved in breaking down carbohydrates, some in breaking down fats, and some in breaking down proteins. But first, we like to take a deeper look at what might cause hair, skin, and nail issues in the first place. Because without addressing the root cause, biotin will just attempt to remedy the symptom.

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. Biotin taken as a dietary supplement is relatively safe and unlikely to have toxic effects since it’s water-soluble (1). Antiepileptics are commonly used to treat seizure disorders, nerve pain, and bipolar disorder. Retinoids are a class of compounds derived from vitamin A, commonly used to treat acne, psoriasis, and other dermatological conditions (11). People who take certain classes of medications like antiepileptics and retinoids are also at risk of a biotin deficiency (9).
