Mine is average density, medium-coarse, low porosity.

If i do a great job squeezing out water with the t-shirt, about 5 hours to dry.

Mind you, this is WAY less time than it used to take!

I do not think slow drying hair is any sort of indication of hair needing moisture or whatever, it's more to do with porosity, texture, and amount of hair. And how much stuff you put in it - I've always left in conditioner and either gel or mousse so that makes it slower I am sure.
When mine was all one length and over a yard long, it took 36 hours to dry, usually. A night, a day, and a night. Combination of length, density, texture and porosity.
Like Ped, mine doesn't dry if it's wrapped or braided. If I ponytail it will still be wet in the inside the next day, roller sets never dry without some serious heat.

But I do air dry usually anyway. Wake up at 5 so it's always dry by lunchtime and my work doesn't care, other people with curly hair come in with it wet, it's not just me.
