Texture confusion

Okay ladies,

I know that black hair typically has two (or more) different textures on any one person's head.
I, myself, have big, smooth, 3b type curls at the back of my head--near the nape of my neck.
The rest of my curls, throughout, are corkscrew curls that vary in being loosely & tightly wound. (I still haven't figured out what hair type these corkscrew curls of mine are, as far as 3c or 4a, so if someone could help me with that, that'd be awesome)*

My main issue, is that right in the center of my head (the crown), my hair is extremely coarse. Sometimes I worry that it's not absorbing the moisture like the rest of my hair (if it's possible for one part of your hair to do that), but then there are times when it feels like it's moisturized, but the feel of it is more wiry than anything.

Help?

the middle of my hair is very very coarse as well nothing at all moisturizes it...it was like that too when I had a perm in my hair....it would always be the first area to grow in first when i needed a touch up...i absolutely hate it with a passion....like right now it feels so rough...sigh....i gave up the battle trying to deal with it....

My hair @ the crown is the same way...just as stubborn as it wants to be. It looks like a worn Brillo pad and has not one defined curl. It's just my type of hair, and nothing I do to it will change the texture. All I can do is keep it moisturized (more than the rest of my hair) and treat it like a newborn--gently. It can be a major PITA, but fighting it won't make it any easier to manage. So, I learned how to work w/ it instead of against it.

Ditto Chrs ... I am MUCH more liberal with product on the crown than elsewhere on my head, but only water-based moisturizers, as the porosity is significantly less than the rest of my hair as well ... the last place to dry, the place oil just sits, etc.
