Hair hasn't been touched by any hot irons. Naturally kept straight and loose. Been growing it for a year now. Its 22 inches long and almost 3.5 widths. I wash my hair after every 5-7days. After hair is washed I will put on some argan oil to keep it healthy. I eat pretty healthily, usually salads/egg/chicken/yogurt/ whole grains/fish during the week and during the weekend I will usually make some beef with potatoes/fish/rice.
