Okay ladies, I've gone several months without a touch up, been on the Bargello Plan for several months and been wearing my hair in a protective style (setting hair using goody's twist rollers to achieve loose spirals and air drying), but how can I check to see how much hair growth I've had? I really don't want to use heat to straighten my hair out, but I'm curious, plus I need a trim. Any suggestions would be appreciated.
