10 inches virgin dark brown curly hair

I am Mexican, my hair is virgin, I have not used hair dye or permanent straightening. I don’t iron my hair or use a dryer. I wash my hair with sulfate and paraben free shampoo 2-3 times a week, let it air dry, I don’t smoke, I don’t use drugs. I wear a satin cap to sleep. I avoid pulling it. The products I use are Marc Anthony, Cantu, Aunt Jackie’s.
