for me, when i use the waver, whenever i move it from one section to the next i hold the hair i just finished waving up toward my head, like youre scrunching it and let it cool for a minute, it'll help the wave stay longer. If you want a tighter wave take smaller sections, if you want a looser wave you can take some bigger ones. My hair is pretty fine, so i take smaller sections to i can create more volume, and then i just kinda tossle my hair, sometimes i use a texturizing hairspray like Redken Windblown, it's a soft hold, but gives you airy texture. Sometimes i use some dry shampoo at the roots for volume too. I find the more you tossle your hair the more natural it looks because you get rid of any sectioning you may have showing. And if you find your ends are getting dry you can just take like a drop of your favorite oil and scrunch it into the ends so you don't really disrupt too much.
