Thank you, they are all very valid points. My problem is usually with COLOR. I have to dye my own hair because of alopecia, a condition that the hair falls out in patches and grows back WHITE, it takes years to settle doen and regain natural color. I dye my hair and the piece but they dye differently. I can't get em to match right. DOes anyone know what I suspect is that the hair pice can dye at a different rate than your own hair?
