Benefits of Biotin for Hair Growth – Best Supplements and Dosage

What are the main benefits of biotin for hair growth? First of all, biotin stimulates and nourishes hair follicles and scalp.

It is not uncommon to see biotin as one of the components of hair masks, shampoos and other hair products. The big question is, how do biotin supplements benefit the hair? Biotin which is also known as Vitamin B7 is a water-soluble vitamin that gives energy and nutrients to the body from proteins, carbohydrates, and fats. It enhances the production of Keratin in the hair. Keratin is a type of protein that can be found in the hair, skin, and nails. The production of keratin, therefore, boosts the growth of healthy hair follicles, makes the hair stronger and less likely to fall off.

The lack of biotin can lead to thinning of the hair (alopecia) so to salvage this, people turn to biotin supplements to make their hair thicker and more stimulated.

What Does Biotin Actually Do?

While cases of biotin deficiency may be rare, some people suffer from it so the consumption of biotin supplements will be really helpful to such people. Typically, the amount of biotin one gets from foods like fatty fish, groundnuts, eggs, etc., is enough to give a person all the benefits of biotin like the maintenance of full, strong, and glowing hair. This means that people don’t really need biotin supplements to enjoy their benefits.

Asides from hair, skin, and nails maintenance, a healthy amount of biotin in the body helps keep blood sugar levels in check and break down micronutrients. It is also necessary to keep carboxylases (a type of enzyme) active. Carboxylases are important for the metabolic processes of the body system like the production of fatty acids and glucose.

You may also notice an increase in the volume of your eyebrows, and experience some improvements on your fingernails. Those who suffer from eczema may also benefit from biotin supplements.

Although one of the most commonly known functions of biotin in the body is the production and maintenance of healthy hair and skin, it has other functions like the maintenance of healthy nerves, cells, and digestive tract. Some studies have also shown that biotin can be useful in the treatment of nerve pain, diabetes, and kidney failure.

The reality is that many companies attach biotin to health products that ordinarily have nothing to do with it. This is because they want to add credence to their claims and since many people want to boost their hairs, skin, and nails, they can easily fall for such claims that are still without scientific proofs.

Although this isn’t on the good side, another thing biotin does is cause skin rashes, kidney problems, stomach upset, and problems with the release of insulin when one takes too much of it.

Recommended Volume of Biotin For Hair Growth

Many people jump into taking biotin supplements because they think the fact that those who have biotin deficiency exhibit certain symptoms like thinning of the hair, etc. so if they want their hair to add more volume or look better, biotin supplements should be the magic solution. Although people indulge in this, the logic isn’t very grounded as there is an avalanche of reasons behind thinning hair, and in most cases, these reasons have nothing to do with the lack of biotin.

While biotin deficiency may not be very common, there are some groups of people who are prone to it. Lactating mothers, pregnant women, chronic alcoholics, and vegetarians fall under this category. In cases where people find that they lack this vitamin, they run to biotin supplements to remedy their loss of hair or any other symptoms they may be experiencing.

There are anecdotes to support claims that those who do not get enough biotin in their diets, especially those with thinning hair or nails can get it via supplements, but there isn’t any scientific research to back this claim. There is also no blood test to prove biotin deficiency, so one cannot easily tell what the right dosage of biotin supplements should be.

While Mayo Clinic recommends a daily dosage of between 30 to 100 micrograms of biotin supplements for adults, proponents believe that 2000 to 5000 micrograms is the right dosage to make the hair stronger and get the overall desired results.

Note that biotin is a water-soluble vitamin so excess intake of it is usually passed out of the body in feces and urine. Asides from this known fact, one cannot categorically say whether or not is safe to take it regularly as there are no scientific proofs.

When you take biotin supplements, you need to be faithful with your dosage routine as inconsistencies will cause your results to fluctuate. You have to also understand that just as it is with other supplements, biotin supplements will not make your hair grow overnight. You’ll typically get to notice results after about one month of taking the supplements, but it is also possible for some people to begin to notice differences within two weeks.

If you are taking biotin-rich foods to boost your hair health, you’ll have to take many of them daily to ingest enough biotin into your body. This way, you’ll begin to notice differences after some time.

It is believed that people with alopecia show a positive response when they take the right amount of biotin supplements. It is, however, important to note that those who are treating certain medical conditions need to stop taking biotin supplements as it can interfere with the efficacy of some of your medications.

Does Biotin Cause Body Hair Growth?

It is not uncommon to worry about the possibility of biotin causing your body hair to grow. Since this vitamin is said to boost hair growth, it may also cause the body’s hair to grow, many may think. While this is a very valid concern, it is not the case because unlike the hair on the head, the body’s hair works with a molecular signal. This signal alerts body hair to stop growing when it gets to a particular length. It is thanks to this signal that you don’t have to either shave off, not style the hair on your arm or legs. The only part of the body where biotin thickens hair is the head and eyebrow. Fortunately, many people would rather have fuller hairs on these parts of the body.

Factors to Consider Before Taking Biotin Supplements

Before you decide to take biotin supplements, some important factors should inform your decision. For example, if you have an appointment for a blood test, it is advised that you stop taking the supplements three days before you go to the lab. Regardless, you should let your doctor know that you are taking the supplements. This is because biotin can interfere with the result of your blood test, and can also mess with your medications.

It is generally okay to take biotin supplements, but it is wise to mention it to your doctor before you start taking them, just to be sure that it doesn’t pose any threat to your health. If you have been confirmed to be biotin deficient, your doctor is in the best position to advise you on the right dosage of biotin for you. Your doctor should also let you know the best supplements for your condition.

If your hair seems weak, consult your doctor first to help you decide whether or not biotin supplements are best for you. This is because there is a possibility of some underlying medical conditions that manifest in weak hair. Iron deficiency and deficiency in other vitamins that aid the absorption of iron can also lead to weak hair or nails so biotin supplements may not be what you need.
