Some wavy hair can be layered beautifully, some cannot. It depends on you own hair and the talent of your stylist. My own hair does not look good when i layer the back, not even long ones at the ends. the underneath alwayd looks straighter that the top canopy & it just looks wierd. hair texture, the ammount of frizz, thickness, ALL play a part in deciding what hairstyle will work best for you. I would suggest experimenting with very long layers, no shorter than you are willing to lose if you don't like them. Shorter layers or allover layers have to be grown out unless you want to go short is you are not happy with them. but you never know unless you try!
