so i have 3a hair, close to 3b half the time. and im getting my hair cut tomorrow but the thing is the top layer of my hair is wavy\barely curly and underneath is very curly. ive tried getting shorter layers but then the top of my head is a poofball. ivve heard longer layers work well? my hair is about 3.5\4 inches past my shoulders. any suggestions on what i should do???
