Medium wavy hair styles create a feeling of softness round a woman's face, catching the light and curving it to follow its own lazy, sinuous movements.
Dark and medium coloured wavy hair takes on a burnished feel as the waves travel in and out of the light. Pale coloured waves form complex movements of light and shadow. Medium wavy styles create another range of effects.
But none of these effects can be had with straight hair styles, where light reflects uniformly in a single direction, or with curly hair that shatters the pattern of light completely.
Wavy hair is in a class of its own.
Wavy hair grows differently from one person to the next, and the length of its natural wave is similarly variable. As wavy hair grows it develops its own natural shape.
If you have wavy hair and a medium style, your hair may well have enough length to develop its natural wave completely. But prematurely shortened waves could also take you hair style in new, attractive directions.
If you have long wavy hair now, you should be able to judge the length of its natural wave. Hopefully your stylist can tell you what will happen to that wave when you have it cut at different hair lengths - short, medium, medium long - and what styles will suit you.
Medium wavy hair styles can be funky and fun, too. With less length there's less weight, letting your hair spring up into a shorter, choppier, bouncier wave than you'd have with longer hair pulling the shape down..
