The two most prevalent terms in the hair care industry arebiotinand keratin. But what are their roles in the structure of your hair? We understand that the science behind these topics can be confusing, so we decided to break it down in the simplest way possible! 

Keratin

What is it? 

Keratin is a type of protein that makes up our hair, skin, and nails (2). 

What is its role in the body? 

In the body, keratin acts as a protective protein. This means that organs made up of keratin are less prone to scratches, tearing, and breakage. Ever wonder how our internal organs are so strong? Thank keratin! The protective protein is found to guard against pollutants and injury throughout the body. 

Can you consume it?

Yes! Keratin is often found in topical hair products but can also be taken orally as a supplement. If you want to see an immediate difference in the health of your hair, opt for a professional keratin treatment at your local salon.Pro tip: Gradually implement keratin into your routine, as creating a protein buildup can occur. If there is an overabundance of protein within your hair, you may end up experiencing adverse effects. 

Biotin

What is it? 

Biotin is one of the many B vitamins often found in food. 

What is its role in the body? 

More specifically, biotin helps turn macronutrients in food (carbs, fats, and proteins) into energy for the body (1). Pretty cool, right? 

Can you consume it?

You sure can! Biotin is often found somewhere on the ingredients list of your favorite hair care products. However, the benefits are much more effective when the vitamin is part of your diet. With this in mind, be sure to implement biotin-rich foods into your daily meals.Note: Since biotin is used for fuels, it doesn’t remain in the body for too long. So, to ensure that you’re getting the perfect dose every single day, incorporate a biotin supplement as one of your daily habits! 

How are the two related to one another?

Biotin stimulates keratin production, which is known to increase the rate of follicle growth (3). You need to consume more biotin to reapall the benefits for stronger, healthier hair. Or, think about it this way: biotin creates keratin, but keratindoesn’t produce biotin.
