Hi! I'm definitely a 2A...fine hair with waves and a few curls. Short hair gives me curls, longer hair waves. Right now, I'm suffering triangle head - where the hair on top is flat and the ends fan out...my hair is layered and actually cut for fine hair to give me volume. I'm really having a hard time explaining to the lady who cuts my hair how to cut it so I don't get this odd shape to it. Hair is below collar length in back and the back looks great...it's the sides and top giving me fits. Any suggestions for short-medium hair cuts that will prevent the triangle effect? Thanks!
