There are some cases where certain dietary or other habits have caused a deficiency of biotin. Studies have found that women who smoke can increase the metabolism of biotin in their bodies and cause a deficiency. Another case showed that eating raw eggs — particularly the whites of the eggs — on a regular basis can also create a biotin deficiency.
In this instance, the deficiency brought about a condition called biotin-responsive limb weakness. This condition mimics quadriplegia. The regular consumption of raw egg whites was used in another research study that showed this caused a biotin deficiency as well.

Biotin deficiencies are rare, so research into their symptoms is limited. However, a few studies have suggested causal links between biotin deficiency and some conditions. An animal study also found a correlation between biotin and zinc homeostasis in the skin. However, it is essential to note that controlled human tests have not confirmed direct causality for either of these findings and that further research is necessary.
Foods with a notable concentration of biotin include:. Various other nutritional supplements could improve hair health. However, human trials have not supported the efficacy of many of these remedies for this purpose.
