Science or phenomenon of how and why different hair textures behave the way they do?

How hair behaves is determined by it's thickness, porosity and straight or curl pattern but to me, all hair is made up of the same fibres, structures and proteins. Why is it that curlier textures have to be extra cared for well after a wash whereas straight or wavy textures can be washed, air dry and still be soft and shiny to the touch? It makes more sense to me for a straight surfaced strand to lose moisture and be dry than a curly strand surface, which I would think because is curled up, moisture is easier to retain and would be like a tangled jungle to get through in order for it to be lost. Please explain the science or phenomenon of this.
