The Biotin and Hair Loss | Cause of Biotin Deficiency
Why there may be a biotin deficiency? The causes are many, among the most important are:
- Crash diets to lose weight, they do not include sufficient amounts of biotin, iron and other nutritional requirements (these deficiencies accelerate hair loss).
- Pregnancy.
- Prolonged treatment with antibiotics (sulfa) to kill bacteria that produce biotin.
- Prolonged treatment with certain medicines to treat or control epilepsy (eg carbamazepine, primidone, phenobarbital or valproic acid).
- Eating raw eggs (as they contain a substance called avidin that prevents biotin absorption).
- Malnutrition.
- Rapid weight loss (called telogen effluvium precipitates, ie, put the hair follicles in the resting period, making hair fall out).
- Food intravenously (directly into a vein).
