Biotin 101: What Is It

Keeping hair healthy is a top priority for many people, and knowing what to use or put in your body to promote healthy hair can go a long way.  Learn how biotin is good for hair, what hair care products like shampoos do to promote biotin, and a few of our favorite biotin-rich products that can help keep all kinds of hair, including color-treated hair, looking radiant.  

What is Biotin?

Biotin, also called vitamin B7, promotes healthy hair growth and prevents hair loss. It can be found in many foods you can consume but is also often found in hair care products. Biotin promotes the body’s keratin production. 

Many benefits of biotin include:  

  • Improve nail strength and health 
  • Maintains the mucous membranes of the skin, meaning your skin will look and be healthier 
  • Plays a role in blood sugar regulation  
  • Prevents birth defects and maintains health of pregnant people 

Is Biotin Good for Hair?

Yes, biotin plays an important role in keeping hair healthy by increasing the rate of follicle growth along with keratin production which impacts hair, skin, and nails. Biotin is found in many foods such as:  

  • Walnuts and peanuts
  • Milk 
  • Egg yolks 
  • Salmon, pork, and sardines

Along with consuming foods that have small amounts of biotin, using a biotin hair care product like biotin shampoo can help minimize shedding that contributes to hair loss and thinning. 

How Biotin Shampoos Work

Shampoos infused with biotin are believed to improve scalp circulation, increase hair density, and strength hair follicles. Using biotin shampoos can help hair feel more nourished and thicker. If you have thin hair, biotin can aid in making it thicker and fuller. Source
