The first thing that you should know about the wave haircut is that it works mainly for Afro hair texture. Otherwise, you will get S waves instead of 360 waves. For an actual 360 hairstyle, you will need to use a special brush with a soft and hard side, a hair dryer and a styling pomade.
Also, you need to prepare your hair for styling. Grow it until it equals a 1.5 guard, which is 3/16” or 4.8 mm. Then, spritz the hair with water so it is damp. Grab the brush and using its hard side, brush your top to the front. At the same time, blow it dry with the hair dryer set to medium heat. Brush the rest of the hair with the grain and keep on blowing it with the hair dryer. As a result of brushing and heat use, your hair forms an S shape, which creates a 360 wave pattern when repeated all over the head. Finish off the hairstyle using the soft part of the brush and a tad of hair pomade.
