20 Best Biotin Serum For Hair Growth (2022 Updated)

Biotin is a water-soluble vitamin that is part of the B complex vitamins. It is also known as vitamin H or coenzyme R. Biotin is necessary for the metabolism of carbohydrates, fats, and proteins. It plays a role in the health of the skin, hair, and nails.

Biotin is found in a variety of foods, including eggs, nuts, and legumes. It is also available in supplement form.

Biotin is often promoted as a supplement for hair, skin, and nail health. It is claimed to increase hair growth, prevent hair loss, and make nails stronger and healthier. There is some evidence to support these claims.

A small study published in the Journal of Cosmetic Science found that biotin supplements increased hair growth in women with thinning hair. Another study found that biotin supplements improved nail quality in people with brittle nails.

Biotin is generally considered safe when taken in recommended doses. Side effects are rare but may include skin rash, nausea, and stomach upset. Biotin should be taken with a meal to prevent nausea. High doses of biotin (more than 5 mg per day) can interfere with laboratory tests, such as those for thyroid function and diabetes.

Conclusion

Biotin is a water-soluble vitamin that is part of the vitamin B complex. It is also known as vitamin H or coenzyme R. Biotin is necessary for the metabolism of carbohydrates, fats, and proteins. It plays a role in the health of the skin, hair, nails, and nerves.

Biotin is found in a variety of foods, including eggs, milk, nuts, and legumes. It is also available in supplement form.

A number of studies have looked at the use of biotin for hair growth. One study found that biotin supplementation increased hair growth in women with thinning hair. Another study found that biotin supplementation resulted in an increase in the thickness of the hair shaft in people with brittle nails.

However, more research is needed to determine the effectiveness of biotin for hair growth.

Biotin is generally considered safe when taken in recommended doses. However, some people may experience side effects, such as skin rashes, diarrhea, and nausea. If you experience any adverse effects, stop taking biotin and consult your healthcare provider.
