I used to think hair fall was just a “seasonal thing.”

You know — those months when clumps of hair seem to clog the shower drain and no amount of oiling seems to help.

So, like many people, I reached for a bottle of biotin. “Good for hair,” it said. It was affordable, everywhere, and even Instagram recommended it. I didn’t really know if I needed it. But hey, what could go wrong?

A few weeks in, nothing drastic happened. My hair didn’t magically stop falling. My skin didn’t glow. But what I did start to notice was how many of my friends were doing the same — buying biotin without checking if they were deficient in it at all.

That’s when I started to look deeper:

• Was biotin really the magic solution for hair fall?
• What does it actually do in the body?
• And how do you know if you need a supplement?

In this blog, I’ll break it down —

• What biotin actually is
• How much your body needs
• Natural sources vs. supplements
• What science says about hair growth
• And whether you really need that bottle of biotin or not

1. What is Biotin, Really?

Biotin, also known as Vitamin B7, is a water-soluble B-vitamin that plays a crucial role in converting food into energy.

It's also important for:

• Fatty acid synthesis
• Amino acid metabolism
• Cell growth

Your body needs it in tiny amounts, and it’s involved in keeping your hair, skin, and nails healthy — which is where the hype around hair growth comes in.

2. How Much Biotin Do You Actually Need?

According to the National Institutes of Health, the recommended daily intake is:

• Adults: ~30 micrograms/day
• Pregnant women: ~30 mcg
• Breastfeeding women: ~35 mcg

Psst: Most people already get this amount through a regular diet.

3. Natural Sources of Biotin

Biotin is widely available in common foods, such as:

• Egg yolks (cooked)
• Nuts & seeds (almonds, peanuts, walnuts, sunflower seeds)
• Legumes (peanuts, soybeans)
• Chicken / Beef liver
• Whole grains
• Spinach, broccoli
• Bananas, avocados
• Dairy products

So unless your diet is extremely restricted, you're likely covered.

4. Biotin Craze in India: Where Did It Start?

Today, biotin supplements are found in everything from hair gummies to protein powders to shampoos. Influencers, dermatologists, and even your local chemist will recommend it for:

• Hair fall
• Nail brittleness
• Skin glow

But most people never get their biotin levels tested — because deficiency is rare and usually caused by:

• Poor diet over a long period
• Alcoholism
• Pregnancy (sometimes)
• Biotinidase deficiency (a rare genetic condition)

5. Does Biotin Actually Help with Hair Loss?

What science says:

• Biotin helps with hair growth — only if you're deficient.
• Most people who see results were either deficient or malnourished.
• Healthy individuals with normal levels don’t get noticeable hair growth with supplementation.

Study Example: A review in the Journal of the American Academy of Dermatology (2017) found limited evidence of biotin helping hair growth in healthy individuals.

6. What Should You Do Instead?

• Eat a balanced diet rich in biotin-rich foods.
• Get your nutrient levels checked before starting any supplements.
• Focus on overall gut and metabolic health, which affect hair quality more than one vitamin.

7. So, Do You Really Need That Biotin Supplement?

Maybe — but probably not. If your diet is decent and you're not facing chronic health issues, your body’s likely already getting enough.

Taking more won’t hurt (biotin is water-soluble and excess is excreted), but it might not help either.
