Biotin plays a significant part in the prevention of hair loss. Most nutritionists agree that biotin is one of the important vitamins for supporting hair growth. Biotin is a water-soluble B vitamin (also known as vitamin B7 or vitamin H). It is not known exactly what to expect from a biotin overdose, but it seems that a biotin overdose is unlikely to cause serious problems in most situations.
Yes it causes!
