Learn the truth about using biotin for hair growth.


Research has demonstrated that biotin hair growth supplements do not seem to improve hair growth except in extreme cases including:

  • Severe deficiency from malnutrition
  • Removal of portions of the intestines
  • Malabsorption caused by gastrointestinal disease
  • Neurological diseases
  • Enzyme deficiency
  • Treatment with antiepileptic medication or broad-spectrum antibiotics

Overconsumption of raw egg whites can also cause biotin deficiency.

In short, if you are healthy with a varied diet and not biotin-deficient, adding extra biotin will not alter your hair’s growth.


I actually disagree. I've been taking the suppliments for several months now and I have seen regrowth in thinning areas and my nails have never been better. I am a healthy person with a varied diet, but these suppliments have been great for my hair and nails. I'm still a believer.

I actually have experienced Dandruff as a result of these pills. I'm not sure if it was too strong of a dosage, but I have never had dandruff problems. And it caused me to HAVE to wash my hair weekly. But this is my experience.

Why in an earlier article did NC suggest taking a multivitamin with Biotin and fish oil for hair growth and strenght?
