@LegsLegsLegs Do you have a pic of your wig you are trying to work with? I would start by washing the hair- brushing through with conditioner, rinse. Then going light with product (maybe a mousse), mostly finger comb and scrunch, and see how the curls set after airdrying. If the curls weren't curly enough, I would probably try to steam-set them myself lol before I bought another wig.
It's difficult because the curls in raw hair are rarely consistent through the length, let alone from one bundle to the next. So a certain amount of prediction goes into how curls will look after 'the work'. Even on processed curly hair. If you do buy something else, opting for made to order vs stock, you can be specific about certain requests. You can send or ask for pics from vendor, so you can see if the curl will work for you before purchasing. I know exactly what you mean about the oversaturation of that curltype/ bodywave look (insert nodding head emoji).
