Don’t we all dream of luscious healthy hair? But daily damage, heat, pollution, chemicals, and styling can damage your hair. Another damaging factor is not eating a healthy balanced diet. We need the right amount of vitamins and minerals in our diet for our skin and hair to be healthy. One such vitamin is biotin.

What Is Biotin? 
Biotin, or Vitamin B7, is a part of the vitamin B complex group. It is a water-soluble vitamin and is associated with healthy hair and skin, cardiovascular, nerve, and digestive functions. The word biotin comes from the Greek word ‘biotos’ which means life or sustenance. Since it is a water-soluble vitamin, our body doesn’t store biotin.

The daily requirement of biotin varies at every stage of life. 

  • 5 micrograms daily for infants

Biotin for Hair
It is a common myth that biotin is the sole ingredient needed for hair growth. Although biotin for hair growth is extremely important, but the biotin isn’t the only nutrient needed. A balanced mix of vitamins and minerals promotes hair growth.

How does biotin help in hair growth? 
Our hair is made up of keratin, a type of protein. Proteins are formed by amino acids. And these amino acids are formed on reaction of enzymes with biotin. The biotin present in our body contributes to give healthy hair, skin, and nails. When ingested, either from food sources or from biotin supplements, it reacts with cell enzymes and produces amino acids, the building blocks of protein. This helps in hair growth. But apart from biotin, you need to eat food with a healthy balance of vitamins supplements and minerals, follow the stress-free lifestyle, and take proper care of your hair. If any one of these factors is missing, it may affect your hair. Hair loss and thinning of hair are commonly seen. A major cause is an erratic lifestyle – junk food, harsh chemicals, heat styling, hair coloring, pollution, and heat all cause hair damage in more than one way.
Biotin can be found in food. There are various sources of biotin. But a lot of people fall short of the daily requirement and take biotin supplements for healthy hair. It is essential that you talk to your doctor and then take biotin tablets.
If you want thick luscious hair, then biotin is the answer for you. Consume biotin rich food or biotin tablets. But keep in mind not to exceed the prescribed dosage. An overdose of biotin may cause medical complications.
