I have wondered this for a few years now, and yesterday after writing about it in an email ,i remembered you are a hairdresser and maybe you know the answer. All my life i had poker straight hair. even when i got a perm it went right back to straight within a month. When i was about 36 i noticed a hair or two that looked to be wavy or even curly. well lo and behlod here i am at 41 and my hair is now wavy. Some spots more wavy than others. Its odd my hair is still straight right in the front, but the sides and back are wavy. Odd i know.... What gives? Do you have any idea why these crazy things happen? If i remember correctly, this also happened to my mom ,so maybe its genetics. Its odd because i remember years ago using curlers to get some wave and body and now i am using large rollers to get some straightness....lol
