how often should one get a hair cut? saw my last post and it has been more than a month. the hairdresser chided me when she found out that my last haircut was 3 months ago. hey, why the need to keep on trimming hair unless it gets really messy. haircuts need both time and money. not to mention, i hate people messing ard with my head.the curls on my hair are finally growing out, i like my super natural straight hair.
