My hair has actually gone the opposite direction, but yes I have had a slow hair change. As a teen, my hair was much thicker, frizzier, and more 3c. Now in my 20s, it is 3a/b, and not as thick and unruly. I have known several curlies to have these sorts of changes as they age... I think it has to do with hormonal and body changes over the years. I know many women report hair texture changes after having children, menopause, etc. I know my hair changed a lot after puberty, etc.
My hair: 3b, corkicelli, medium porosity, medium texture, medium/thick density
