I ask this question because my hair always seemed healthy and while flat ironing I was extremely careful not to over heat my hair. Never smoke from iron or leave iron on hair longer than 2 seconds. Also, I'd let my hair dry naturally to minimize damage.

I also ask this question because I wonder if my 3b hair texture will change to 3a or 3c or something else. This is a concern because if it changes, I will have to change the way I've been styling it.
