No ripples at all...the thing basically molds to the shape of your head and for 3 day attachment u don't really need anything more than 2 coats of got2b glued (one to the head and another to the base). I like to mix got2b glued gel with a bit of the freezing spray in a small cup/bowl then apply using a craft brush.I also put 2 extend-a-bond mini tabs on each side above my ears for added security,but you can do without them and you'd still get a solid 3+ day hold.
