Waves have been around for centuries!
You can see ancient egyptians on heiroglyphs with 360 waves and people today are even sporting 720s.

Waves are curls trained to lay down with the use of a brush and durag. Combs help you get to the next level.

Everyone with curly hair can get waves. Some hair takes longer to curl than others. If your hair doesn't take much length to become curly then that means shorter wolf sessions for you!
