What Does Biotin Do For Your Hair?

What Does Biotin Do For Your Hair?

If you worry about thinning or brittle hair, you’ve probably considered biotin as an option for amping up your hair growth game. Biotin is a commonly marketed ingredient in hair growth supplements and shampoos, so it's no surprise that you may consider purchasing a bottle or a product that contains biotin as part of its formula.

We’ve gathered our top seven reasons why biotin is great for your hair, so keep scrolling.

What Is Biotin?

You’ve heard the word before, but do you know what it is? Biotin is a B7 vitamin (often called vitamin H) that is an essential nutrient. It is a water-soluble vitamin that plays a crucial role in the growth and health of your hair, skin, and nails. This ingredient graces the bottles of many hair care products, promising thicker, fuller, and stronger hair. Sounds great, right? Let’s talk more about biotin and the seven reasons why it is great for your hair.

What Are The Benefits of Biotin For Your Hair?

Biotin is readily available in foods consumed everyday including: egg yolk, mushrooms, nuts, meats, soybeans, legumes, and grains. So, incorporating more of these into your diet may encourage healthier hair, skin, and nails. There are many benefits of biotin for your mane, including:

1. Biotin May Encourage Hair Growth

Biotin is great for combating hair breakage, strengthening and thickening the hair, and promoting hair growth. This is why biotin is the main ingredient in many hair growth supplements and hair serums.

2. Biotin Promotes Thicker Hair

Another popular claim for using biotin is that it promotes hair thickening. It is an ingredient in many hair care shampoos, conditioners, and supplements for this very reason. 

3. Biotin Protects The Hair

When used as part of a hair care formula, biotin makes hair less likely to break because it helps strengthen the strands and makes them thicker. As hair becomes stronger and less brittle, the chances of breakage decreases. 

Biotin is great for combating hair breakage, strengthening and thickening the hair, and promoting hair growth.

4. Biotin Enhances Shine & Moisture

According to some studies, hair quality enhances when biotin supplementation occurs. These enhancements include shine and thickness by helping to maintain its moisture – two indicators of healthy hair. Additionally, hydrated hair is essential for your hair’s elasticity and for avoiding breakage.

5. Biotin Promotes Healthier Hair & Scalp

Biotin improves the keratin (protein) structure of hair, nails, and skin. It also improves hair density and volume. 

When considering that our scalp is simply skin, a healthy scalp supported by biotin promotes healthy hair growth.

6. Biotin May Prevent Hair Loss By Suppressing Swelling

Some types of hair loss result from redness and swelling of the scalp. Another property of biotin is its ability to fight against swelling, which in turn may combat hair loss by lessening redness and inflammation in and around hair follicles. 

7. Biotin Maintains Healthy Skin & Nails

As a bonus, biotin promotes healthy skin and nails. Biotin supports the production of fatty acids that nourish your skin and help oil glands function correctly. And, ss mentioned above, it can also help support the infrastructure of keratin, the protein that makes up not only your hair, but your skin and nails too.

How Much Biotin Do You Need?

Biotin is water-soluble (like all other B vitamins) so it passes through your body when you urinate - between 30-100 mcg of biotin per day is recommended for most adults. A biotin deficiency may result in brittle nails, hair loss and breakage, and red rashes if you're not eating a healthy diet or otherwise getting enough of the vitamin. 

Those who aren’t sure if they consume adequate amounts of the vitamin can incorporate biotin through pill or powder form, or through foods such as liver, eggs, milk, and some vegetables. Our Daily Scalp Essential, for example, offers enough of the recommended daily intake in just two capsules without any taste or aftertaste (not to mention, a host of other amazing ingredients like turmeric and a proprietary blend of adaptogenic mushrooms).

What Does Science Say About Biotin & Hair Growth?

Keratin is the protein foundation of your hair, nails, and skin. Science proves that biotin is involved in keratin’s infrastructure. So healthy hair and biotin are related for sure. Studies show that biotin deficiencies result in thinning hair and brittle nails, and biotin supplementation has the reverse effect, resulting in stronger, longer hair and nails.

While additional biotin studies still need to be conducted, many people find that this vitamin positively changed the way they look at hair care forever. 

Does Biotin Have Side Effects?

While uncommon, taking too much biotin may cause side effects such as acne, digestive upset, skin rashes, and insulin release problems. It’s always a good idea to talk to your doctor around any concerns.
