When Should I Apply Minoxidil After I Take a Shower?

I have thinning hair on the top of my head. Should I apply minoxidil after a shower when the hair is still damp, or wait till it dries? If I apply when it is wet, it seems like more gets to the scalp since less gets absorbed by the hair and is easier to apply in between the hairs. But if the skin is nearly saturated with water, won’t less medicine get absorbed? The instructions don’t cover this.

I would use a towel to dry your hair and then apply minoxidil while the scalp circulation is increased from the warm water.
