16+" very thick, heavy dark brown virgin hair. Very smooth, soft, and easy to manage. Color is multi-dimensional, containing color variation from black to blonde, including red.
Washed and conditioned 1-3 times per week, never colored, heat treated, or heat dried. Balanced diet, no smoking, only occasional drinking.
As you can see it is not my whole head of hair, but it is so thick it still gives me a ponytail more than an inch thick and two inches in circumference.
It's about 18" to a buzz length, and I'm willing to go there for the right price.
