100% virgin hair, no chemical treatments or color. I wash my hair every 2-3 days. Blow dryer and straightener used once a week or less. Smoke free, my hair is air dried after washed and I don’t normally style it or use product in it. I have thick hair (I am Lily). As a child I had curly hair,weave hair,as a result my hair has some beautiful dimension, if you look it closely, it looks like it has natural highlights.
