I'm still learning, but from what I can tell it's 2c, thick, and medium texture.
I am not sure about the porosity, but I think it's normal? It's totally virgin and has never been dyed, permed, or really had any kind of chemicals used on it at all. It tends to take HOURS to air dry, but for the past two years I've only used a dryer on it maybe three or four times. Basically, I think it's as undamaged as it can get.
