1. Biotin. Biotin (vitamin B7) is important for cells inside your body. Low levels of it can cause hair loss, skin rashes, and brittle nails.
Vitamin B: There are multiple B vitamins. The most commonly known in relationship to hair growth is Biotin. Vitamin B carries oxygen and nutrients to the scalp. Vitamin C: Vitamin C is required for creating the protein collagen, an important part of hair structure.
Biotin is a B vitamin that plays a major role in promoting the growth of healthy hair. In fact, biotin is so closely related to the growth of hair that studies have found that 38 of women with hair loss issues have biotin deficiencies.
Biotin, also known as vitamin B7, stimulates keratin production in hair and can increase the rate of follicle growth.
One of those vital nutrients is B12, also known as cobalamin. B12 promotes healthy hair growth by assisting in the production of oxygen-rich red blood cells, which feed hair follicles. Your hair is made of a protein called keratin.
Biotin is also known as vitamin B-7. It forms fatty acids and glucose. It also helps metabolize carbohydrates and amino acids, and it aids in breaking down fat in your body. These functions make biotin an important part of creating the energy your body needs.
Prevents Hair Loss
Vitamin E, with its antioxidant properties, fights this oxidative stress, which is one of the major causes of severe hair fall. In a way, Vitamin E blocks the erosion of your scalp tissues due to free radicals, thus, preventing hair fall as well as premature greying.
B Vitamins are good for hair growth, especially biotin. Vitamins A, C, and E are also good for hair growth and preventing hair loss. Talk to your dermatologist before taking any supplement as individual results vary.
One role vitamin D plays is stimulating new and old hair follicles. When there isn't enough vitamin D in your system, new hair growth can be stunted. Vitamin D deficiency has been linked to alopecia, the autoimmune condition that causes bald patches on the scalp and other areas of the body.
Vitamin C Benefits for Hair
Vitamin C benefits for your hair are from a necessary property within the vitamin that creates the protein, known by the more popular term, collagen. Vitamin C promotes hair health, reduces hair loss and improves hair growth. Vitamin C deficiency can also result in dry hair and split ends.
When taken by mouth: Biotin is likely safe for most people when taken in doses up to 300 mg daily for up to 6 months. But it is more commonly used in lower doses of 2.5 mg daily. When applied to the skin: Biotin is likely safe for most people when applied in cosmetic products that contain up to 0.6% biotin.
Takeaway. Your body makes enough biotin on its own through your dietary intake each day. Therefore, you shouldn't take biotin supplements unless directed by your doctor. There are some rare health conditions that can cause some people to need biotin supplements on a regular basis.
Over-supplementation of certain nutrients, including selenium, Vitamin A, and Vitamin E, has actually been linked to hair loss [4,8–11].
For hair loss, it is suggested that you supplement with 3 mcg or more of B12 per day to see results.
Biotin is generally safe to combine with most vitamins; however, there's little research to support its use if you don't have a deficiency.
But for strengthening hair, a minimum dose of at least 2000 mcg is often advised. To encourage faster hair and nail growth, some supplements are available with 10,000 mcg biotin. Mayo Clinic states that 10,000 mcg is a safe dose, as no adverse side effects have been noted to date.
What is the best biotin dosage for hair growth? The OZiva Plant-Based Biotin 10000 is the best biotin tablet for hair growth.
The best time to take biotin is in the morning, with a full glass of water. Biotin is best taken on an empty stomach 1 hour before eating or 2 hours after your last meal. You should aim to take biotin at the same time each day to stay on track.
Biotin supplements can cause problems if you take too much. Side effects can include skin rashes, digestive upset, problems with insulin release, and kidney problems. As with any supplement, the safety of long-term or high-dose use isn't known.
What's the Maximum Safe Dose of Biotin? The Mayo Clinic states that no side effects have been reported for biotin in amounts of up to 10 milligrams (10,000 mcg) per day. This is double the amount of biotin that's included in our biotin gummy vitamins.
A small trial from 2010 found that vitamin E supplements improved hair growth in people with hair loss. It's thought that the vitamin's antioxidant properties helped reduce oxidative stress in the scalp. Oxidative stress has been linked with hair loss .
Zinc plays an important role in hair tissue growth and repair. It also helps keep the oil glands around the follicles working properly. Hair loss is a common symptom of zinc deficiency ( 13 , 14 ). Studies show resolving zinc deficiency with supplementation may reduce deficiency-related hair loss( 15 , 16 ).
