How Does Biotin Work for Hair Loss Prevention & Help Hair Growth?

Biotin, also known as vitamin B7, is a water-soluble vitamin that plays a vital role in the health of our hair, skin, and nails. It is commonly included in many hair care products and supplements due to its benefits for hair growth and reducing hair loss. People often turn to biotin supplementation to address hair loss concerns and promote healthier, stronger hair.

Hair loss can occur due to various factors such as nutrient deficiencies, hormonal imbalances, or genetics. Biotin is believed to support hair growth by improving the keratin infrastructure, which is the protein that makes up our hair. This essential vitamin helps to strengthen the hair follicles and nourish the scalp, creating a pleasing environment for healthy hair growth. But how exactly does biotin help to prevent hair loss? Let's explore the mechanisms behind its effectiveness in the following sections of this blog.

Is Biotin Beneficial for Hair Growth?

The answer isn’t completely straightforward. Biotin is a B vitamin–although, funnily enough, it is known as vitamin H. It is crucial for cell growth and cell energy production. This is why many believe biotin helps hair growth.

And, it has in fact been shown to make hair grow longer and faster.

So, biotin is really used in hair growth products for a good reason. Unfortunately, many of the "fancier" products on the market combine biotin with a long list of useless ingredients and charge an arm and a leg. (Stay away from these!)

Does Biotin Prevent Hair Loss and Increase Hair Growth?

For people who are experiencing hair loss or thinning because of a biotin deficiency, taking a biotin supplement can help restore hair growth. Biotin deficiency is a rare condition that typically occurs in individuals with specific medical conditions. It also occurs in individuals who have undergone certain medical procedures that interfere with biotin absorption.

There is little evidence that supports biotin increases hair growth. However, the evidence is slightly stronger that biotin prevents hair loss. Also, biotin supplementation can provide the body with the biotin it needs. For people whose hair loss is caused by biotin deficiency, taking a biotin supplement is an easy way to stop excessive hair shedding and support healthy hair growth.

Biotin supplements effectiveness also varies from person to person. Some may notice improvements, while others may not notice any significant changes.

How Much Biotin Should I Take for Hair Loss Prevention?

Biotin (Vitamin B7) daily intake can vary depending on factors such as age, sex, and specific health conditions. The daily recommended biotin intake for hair loss treatment should be 30 micrograms (mcg) for adults if you want to make sure that you are getting an adequate amount of biotin.

Many foods like eggs, nuts, seeds, fish, and meat naturally contain Biotin. So, most of the people obtain sufficient biotin through their regular diet. That's why biotin supplements for hair growth are typically unnecessary for individuals with a balanced diet.

What Types of Biotin Are There?

Biotin is already available in different foods that you consume every day. Also, it is available in various forms, primarily as dietary supplements. Depending on individual preferences and needs, these supplements come in different types and formulations. Here are some ways you can get biotin for hair growth:

Biotin-Rich Foods

There are varieties of foods both plant-based and animal-based that contain biotin. Consuming these kinds of foods is the best way to get biotin in your body and maintain healthy biotin levels. Here are some biotin-rich foods:

  • Eggs
  • Nuts
  • Seeds
  • Legumes
  • Beef
  • Salmon
  • Pork Chop
  • Almonds
  • Broccoli
  • Whole Grains
  • Mushrooms

Biotin Capsules or Pills

These are traditional biotin supplements in the form of gelatin or vegetarian capsules, tablets, or soft gels. They contain biotin powder or liquid, along with other inactive ingredients, to form the dosage form.

Biotin Gummies

Biotin gummies are a popular choice for those individuals who dislike swallowing pills. They are typically fruit-flavored and contain biotin in a chewable, gummy form.

Who May be at Risk for a Biotin Deficiency?

Biotin deficiency is relatively rare. It is widely available in various foods we consume every day, and the body requires only small amounts of it. However, there are certain factors or conditions that can increase the risk of biotin deficiency. These include:

Pregnancy: During pregnancy, women may have an increased need for biotin. Some cases of biotin deficiency can also be seen during pregnancy, which are considered very rare. That's why biotin deficiency is also the one reason for hair loss in pregnant women.

Breastfeeding: Breastfeeding mothers can go through biotin deficiency especially if their diet lacks biotin rich foods.

Malnutrition: A diet, which is extremely limited in variety or severe malnutrition can lead to biotin deficiency over time.

Aging: There are some studies that suggest biotin absorption decreases with age. So, older people have a higher risk of biotin deficiency.

Side Effects of Taking Biotin

Biotin is often consumed as it is marketed for potential benefits for hair health, skin, and nails. However, excessive intake of biotin supplements can lead to side effects. This is true for all kind of supplements. Here are some potential side effects of biotin supplements:

Skin Rash: You might develop a skin rash or hives. It is quite rare but can occur in sensitive individuals.

Digestive Issues: In some cases, biotin supplementation might also cause mild GI disturbances, such as nausea, cramps, or diarrhea.

Interference with Lab tests: High doses of biotin supplements can also interfere with certain laboratory blood tests, leading to inaccurate results.
