“The recommended daily amount for adults is 30 micrograms, but a typical Western diet contains more than enough biotin—generally 35–70 micrograms per day,” she says. So unless you’re not getting enough through food—or you were born with biotinidase deficiency (BIOT), a condition that prevents the body from using biotin—chances are you’re not running low, she adds. 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.
Biotin supplement side effects
Male pattern baldness, or male androgenetic alopecia (MAA), is the gradual loss of hair on the scalp. With 30–50% of men experiencing some degree of MAA by the age of 50, many are looking for ways to prevent further hair loss (10). In addition, it’s naturally produced in your body by intestinal bacteria, making it easy to attain healthy levels (4). This article explores available research to tell you whether biotin can help men grow hair and if there are any risks of taking the supplement. If you lack any of these nutrients, try adding some of the above foods to your diet. One medium oyster provides up to 96% of daily zinc needs for females and 75% for males (27).
Causes of biotin deficiency
Biotin supplements have few side effects if you take them as directed. “Biotin supplements and B-complex vitamins are safe for most people, though they may cause a slightly upset stomach,” Barth says. Food should be the first choice when looking for sources of biotin. Results published in 2016 suggested that biotin was a safe therapy.
Biotin and hair growth
Moreover, all cases showed evidence of clinical improvement after receiving biotin. Time to improvement as well as dosage administered varied for each case. Ten of the 18 cases were reports of patients with inherited enzyme deficiency in either biotinidase or holocarboxylase synthetase.
However, according to experts, there are many ways to address this dilemma. Ahead, a dermatologist and a hairstylist share eight ways to strengthen your hair at home. The dose of this medicine will be different for different patients.
False laboratory tests
Most of us expose our hair to heat styling in some way, from diffusers to curling irons. "After shampooing and conditioning, apply a heat protector on damp hair," Hurtado says. "It reinforces a protective barrier to prevent breakage and breakage." The brand is expected to reach around $2 million in sales for its first year on the market, according to industry sources. The strategy is working thus far, with the brand having sold out of its debut product — which only launched in February. Heiden Jones’ philosophy on marketing the product is to distill the science behind it in ways that make the information accessible.
Although rare, biotin deficiency can cause skin rashes, brittle nails, as well as hair thinning and loss. Biotin may support hair growth in people whose hair thinning or loss occurs due to a biotin deficiency. Other vitamin deficiencies may also affect the health of your hair. It’s true that many shampoo brands utilize biotin in their formulas as a way to combat hair loss. However, similar to the research around biotin supplements, the data to support hair growth from biotin-infused shampoo is limited. But there’s no harm really in giving this kind of shampoo a try if you want your hair to feel fuller — but don’t expect a magical regrowth of hair.
The FNB found the available data to be insufficient to derive an EAR and RDA for biotin. The FNB based its determination of AIs for all populations on the amount of biotin in human milk consumed by infants and then used body weight to extrapolate AIs for other groups [11]. One yellow pepper provides up to 456% of the daily vitamin C needs of females and 380% for males (23, 24). To get the widest variety of nutrients, it’s best to consume various types of seeds. Certain seeds like flaxseeds and chia seeds also provide omega-3 fatty acids.
Additionally, low-level laser therapy (LLLT) and platelet-rich plasma injections are popular in-office treatments that may help improve hair density in some people. While researchers say nutrients may directly restore hair growth, the exact doses aren't known. More research is needed to determine the role of diet in hair loss management.
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.
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. Adults need 30 micrograms of biotin each day to avoid a deficiency. Strawberries, blueberries, raspberries, and blackberries are all loaded with antioxidants, like vitamin C, that protect cells from damage.

Oxidative stress occurs when free radicals overwhelm the body’s antioxidant defense system. Vitamin C helps promote collagen production, which can help strengthen your hair strands. It’s also a powerful antioxidant, which may protect hair strands against oxidative stress. Flaxseeds provide a type of omega-3 fatty acid that is not used by the body as efficiently as the omega-3s found in fatty fish. Vitamin E also protects areas of the skin, like the scalp, from oxidative stress and damage.
This vitamin is important for hair growth and affects the production of sebum, which helps keep hair healthy. While you are unlikely to consume excess biotin through food, many supplements for hair, skin, and nail growth contain biotin over the recommended daily intake (1). While more research is needed to understand the connection between micronutrients and hair loss, ensuring you’re getting enough of these 13 foods rich in nutrients that support hair growth is a good idea.
An essential nutrient is one that your body can't produce or can't produce enough of and needs to function correctly. This biotin and collagen shampoo by OGX is a solid drugstore pick. At an accessible price point, it delivers results after just one wash. The FDA reported an increase in adverse effects due to falsely high or low results.

Still, biotin supplements are only likely to prevent hair loss and promote hair growth in people with a biotin deficiency. A limited number of reliable indicators of biotin status is available [7]. In healthy adults, the concentration of biotin is 133–329 pmol/L in serum and 18–127 nmol/24 hours in urine [2]. The most reliable individual markers of biotin status, including deficiency and sufficiency, are biotinylated MCC and propionyl-CoA carboxylase in white blood cells [7].
