Hair fall is one of the most common issues affecting men and women today. Among the many remedies available, biotin also known as Vitamin B7 or Vitamin H has gained massive popularity as a go-to solution for promoting hair health and stimulating hair growth.
But does biotin really work? Or is it just another overhyped supplement in the beauty aisle?
In this blog post, we’ll break down the science behind biotin, explore its benefits, side effects, natural sources, and whether or not you should include it in your hair care routine.
What Is Biotin?
Biotin is a water-soluble B-vitamin that plays a crucial role in converting food into energy. It is especially important for the health of your skin, nails, and yes hair.
In scientific terms, biotin is vital for the keratin infrastructure, which is the basic protein that makes up your hair, skin, and nails.
Is Biotin Deficiency Causing Your Hair Fall?
The good news? Biotin deficiency is rare. But when it happens, it may lead to:
- Thinning hair or hair loss
- Brittle nails
- Dry, scaly skin
- Fatigue or mood changes
If your body already has enough biotin, taking extra may not speed up hair growth. However, those who are deficient or borderline-low may experience improvements.
Scientific Evidence: What Do Studies Say?
Let’s cut through the noise and get straight to what matters does biotin work?
Study 1 (Journal of Clinical & Aesthetic Dermatology, 2012): Women with thinning hair who took biotin-containing supplements for 90 days saw a significant increase in hair volume, thickness, and scalp coverage.
Study 2 (Dermatology Research and Practice, 2015): Researchers found that biotin supplementation helped improve hair health in people who had underlying nutritional deficiencies.
✅ Conclusion: Biotin works best for people who are deficient. For others, results may vary.
Best Natural Sources of Biotin (Daily Food List)
Instead of jumping straight to pills, here are biotin-rich foods you can easily include in your diet:
| Food | Biotin Content (per 100g) |
|---|---|
| Eggs (cooked) | 25 mcg |
| Almonds | 17 mcg |
| Sweet Potatoes | 2.4 mcg |
| Spinach | 6 mcg |
| Broccoli | 4 mcg |
| Mushrooms | 2.5 mcg |

30–100 mcg/day (as per health authorities like NIH)
In most cases, people get enough biotin through diet. Higher doses (2,500 mcg to 10,000 mcg) are often used in supplements marketed for hair growth. However, there’s no official dosage established for hair benefits.
