You see them... but you see them where and for how long? ;)
I have my hair twisted up and out of the way, or braided, or pinned, or clipped MOST of the time. Then as I step out of my car I pull the pin and shake it out before being "out and about".
Blown out straight my hair is past my bra... Curly it's brushing my shoulders.
I tend to go for curls in the summer in this area (humidity)... because I can wash it, throw in a "slow" gel (you know, the cheap ones that take forever to dry?), and walk around with wet hair pinned up for half the day (natural air conditioning). Then, when it's dry I can either wash it again... or let it go down and pin it out of my face. In the dry heat, I can go straight or curly. But in humidity/near the water... the curl comes 1/2 way back and my hair gets poofy because of the humidity AND my sweat. :P Irritating.
In the dry heat going straight my hair either gets headbanded back, or ponytail braid (think lara croft) or the double braid. Or if I plan on having it down at some point... I keep it twisted up and out of my way, and just "pull the pin".
I have girlfriends with naturally straight hair who can just walk around with their hair down and they look grand... but my natural curl won't do it. Not in this climate. I need 105 and higher (or 90s and 0 humidity), so that my sweat evaporates before it hits my skin surface if I'm going to have straight hair loose all day.
