Could My Hair Styling Wax Block Minoxidil from Working?

I understand your view on styling wax clogging the hair follicles not to be a cause of hair loss. However, I have been using the Nizoral 2% shampoo and wonder if my heavily waxed hair style (which doesn’t entirely wash out) could potentially block the shampoo from penetrating effectively into the scalp? Could this also be a concern for those of us on minoxidil?

What is on your hair does not impact the hair that is being manufactured below the skin, but with using wax, the barrier to the skin will prevent the minoxidil from working (and I suppose the Nizoral, as well). Minoxidil works below the skin, but it must have access to the skin to get through it. I tell people that they are best washing their hair before the application of the minoxidil.
