Very straight, very dark/nearly black. My hair wouldn’t curl if I stuck my finger im a light socket, so I gave up & now it’s just very long. (much easier ). You all with curly hair are so lucky ! Green eyes, O-. Mostly Native + a little Irish/Scots, which must be where the O- came from, cause most of us are O+.
