You know how people say that high porosity air dries quickly? How much passing time is "quick"? 20-30 minutes? An hour?
I have both. The back of my head is high porosity and it dries in 30 minutes on its own and shrinks up big time. The front is low porosity, the water sits on it and beads up and it doesn't shrink as much. It can take 2 to 3 hours to dry on its own.
