My hair is 20 inches long and 4 inches thick. My hair is Very healthy and strong. It has been color treated once. I do not use irons or heat. I wash it everyday to every other day. I use Malin + Goetz moisturizing shampoo and their conditioner. I also deep condition every two weeks to a month.
It is typically very straight but can have a wave if in a bun when wet.
