Biotin is a highly recommended nutrient for hair care due to its many benefits. A daily dose of 10mg is recommended.
The Density Plus vitamin complex contains Biotin( in an amount of almost 5 mg) so
if you take two Density Plus capsules a day(recommended dose) it will not be necessary to supplement this dose with extra Biotin as you will be taking the established dose.
However,
if you take a single capsule of Density Plus a day then it is advisable to take extra Biotin(a pill of 5 mg more) to reach the indicated dose.
