There are a lot of variations of wavy hair and the wavy hair texture often varies from piece to piece and does have different results in the Premium Processed and Virgin European hair.
In Virgin European hair the wavy texture can look more natural because the hair has not been colored.
In Premium Processed hair the wavy texture will need to be wash and air dried to see the true wave pattern. It is best to wash the wig and air dry the wavy hair to determine the true wave pattern. Lighter Premium Process hair is not available in wavy hair textures due to the damage it may cause to the treated hair.
One of the benefits to getting the wavy hair texture is that when styled the wavy texture does hold the style longer than the straight texture. You may not need to retouch the styling as often as with the straight texture.
