Is it true that is not recommended to use topical products that contain minoxidil and Zinc PCA at the same time. Right now, I'm using finasteride and minoxidil but I want to add Alpecin ASL (that contains caffeine and Zinc PCA) becouse that lotion had a great effect on my hair growth after 7 months of use when I use it few years ago.The problem is that I red somewhere online that Zinc PCA blocks the penetration of minoxidil. Is it true or false?
