Do it if: Your hair is wavy to curly, medium to thick
Put the scissors down if: You hair is very fine or very straight
Ask your barber to: Keep the sides at a medium length; top to side ratio should be 2:1 and blended.
How to pull it off: Use a medium hold pomade, like Supremo Magic Move Soft, ($24) and place in hair while still wet. Comb straight back.
