Hair-raising Facts on Biotin for Hair Loss

Have you tried taking biotin supplements to improve hair thinning or hair loss (alopecia), but found all it did was strengthen your nails? The reason being is that biotin supplementation works best when a person with alopecia has a true biotin deficiency. But, a true biotin deficiency is rare, especially in the developed world. In fact, biotin deficiencies are not a common cause for those experiencing hair loss. A study published last year in the International Journal of Trichology showed that out of all their female participants complaining of hair loss (541, between the ages of 9 and 92), less than half (38%) had true biotin deficiency.


Why is biotin deficiency rare?

  • It is found in common foods, such as meats, egg yolk, milk, fish, and nuts.

  • Some strands of bacteria in our intestines actually produce biotin that is then taken up by intestinal cells.

What are some possible risk factors for biotin deficiency?

  • Inflammatory bowel disease

  • Alcoholism

  • Smoking

  • Eating disorders

  • Medical therapies like isotretinoin, anti-eleptics, or long-term use of antibiotics

  • Consumption of raw eggs
