If you are using biotin shampoo and it is causing your scalp to become itchy, then biotin is likely to be the cause. However, if you are not using biotin shampoo and your scalp is still itchy, then it is likely due to one of the other factors mentioned above.
Examining Biotin Side Effects
Although biotin is generally considered to be safe, there are a few possible side effects that can occur.
