Regular perm (body wave) it gives beach wavy hair look, compare to digital perm it look less bounchy, more casual look.
Doesn't look like curling iron style, more like somebody who has naturally wavy hair.
We do not use heat like digital perm so wave is able to creates from roots. (digital perm can not do that since rods will be very hot)
You have to make your hair wet with water before you style your hair. When it your hair wet it shows more wave rather than hair is dry.
Which means it hair must be kept hydrated or moisturized by using curling hair care products such as mousse or cream, gel.
