What Does Biotin Do for Hair?

Everyone dreams of having thick, luscious locks. There’s nothing better than a full head of hair that just screams confidence! However, not everyone is so lucky. Whether your hair is falling out more than usual or you simply want to finally meet your hair goals, biotin can help.

Are you wondering “What does biotin do for hair?” Interested in learning how much biotin you need to give your hair a healthy boost? Keep reading to learn everything you need to know about this vitamin and how it may be the missing element of your hair care routine.

What Is Biotin?

Biotin, also known as vitamin B7, is a nutrient that most people get from eating a healthy diet. There are many foods rich in biotin, including:

  • Salmon
  • Eggs
  • Oats
  • White Mushrooms
  • Avocado
  • Cauliflower
  • Cucumber

This nutrient supports many functions in the body, including the metabolization of protein, fat, and carbohydrates. Biotin also encourages hair growth, minimizes inflammation, and can thicken existing hair.

In fact, biotin is often used to treat those with alopecia, which is the medical term for hair loss!

What Causes Biotin Deficiency?

The good news is that biotin deficiency isn’t very common. This is because most people get plenty of biotin from simply eating a healthy diet.

So, what causes biotin deficiency? Research has found that pregnant women may be at an increased risk of being deficient in biotin.

Pregnancy may contribute to subclinical biotin deficiency in healthy women due to the development of the fetus, which requires the rapid dividing of cells. This process requires biotin for the synthesis of certain cells, which can lead to a temporary deficiency.

Other factors that can contribute to or lead to a biotin deficiency include:

  • Genetic conditions
  • Gastrointestinal conditions that inhibit biotin absorption
  • Istretinoin
  • Severe or chronic malnutrition
  • Certain antibiotics
  • Smoking
  • Long-term use of anticonvulsants

Biotin deficiency can also be caused by the overconsumption of raw eggs, which contain a compound known as avidin, but this is rare, as most people don’t routinely eat raw eggs.

Does Biotin Help Hair Growth?

Scientific evidence shows that biotin is effective in promoting hair growth. The vitamin may help hair not only grow faster, but stronger and thicker as well. This means that your hair will be healthier and less prone to breakage.

Like many other supplements, it takes time to see the true results of biotin. In fact, most people don’t experience the benefits for at least three months of consistent use.

What’s nice about biotin is that it can be taken in many different forms. While some people prefer to take biotin capsules or tablets by mouth, there are other products available, including hair oils, masks, creams, and shampoos, and conditioners.

How Much Biotin Should I Take for Hair Growth?

On average, most people ingest around 35-70 mcg of biotin a day from their diet alone. Because biotin deficiency is so rare, the Food and Drug Administration (FDA) doesn’t have a daily recommended dietary allowance.

Biotin supplementation is only recommended for pregnant and breast-feeding women, as well as those with biotin deficiencies. For those who are found to be biotin deficient, it’s suggested they supplement with an extra 30 mcg to 100 mcg a day.

However, some people prefer to take much higher doses, ranging up to 5,000 mcg a day. While there’s no risk of taking too much biotin, in order to see results, you must take the vitamin consistently. Skipping doses will delay the onset of benefits.

Aside from hair growth on the scalp, biotin users have also reported an increase in eyelash and nail growth. So, if you have brittle fingernails or want enviable lashes, supplementing with biotin may help.

Where Can I Buy Biotin?

If you’re interested in taking biotin for hair loss or to improve the health of your hair and nails, you’ll want to find a trusted brand to buy from. While there is no shortage of biotin supplements available on the market, it’s important to purchase from a brand that is reputable and customer-focused.
