@potaa She simply has very thick hair. Kinda silly that it's ALWAYS full of volume (since accumulated hair oil tends to weigh one's hair down no matter how fluffy), but I assume she takes regular baths and uses volume-promoting conditioner. I also have very thick hair, and after I take a shower and it dries it gets really fluffy and curly/wavy. Then, after about a day or so to accumulate hair oils my hair gets a bit flat, but not overly so. With that said, even though thick and fluffy hair is quite pretty, it's really hard to manage sometimes. It tends to develop very strong knots, and it can be a bit annoying to shape/tie with hair ties. Plus, having very thick, long hair can make it difficult to stay cool during the summer.
