I am selling my black hair. I have only rebonded my hair twice. First was in 2008 and second in 2013 and I never had it treated again after that. My hair grows so fast and I cut it every year. It is a little bit wavy due to having to tie it in a pony tail or a bun everyday because I am a mom and it just gets in the way. I applied henna in March because of my gray hair. I do not smoke or drink. And I only wash my hair twice a week. I do not iron or blow dry. It is healthy and naturally black and has no split ends.
