Using Regenepure DR Shampoo

Hey guys I’m wanting to use Regenepure DR Shampoo to combat hairloss. The active ingredient, Ketoconazole, has been shown to be harmful to the liver and decrease Testosterone if taken orally. The shampoo, only applied topically of course, is only like 1 or 2% Ketoconazole. It is believed to have a local effect on DHT in the scalp.

Would you guys recommend this product? Would it enter the bloodstream and cause problems in other areas of my body? Thanks
