 Hi, beautiful. I always get asked from people, what size curling iron you need? I wanna help you today so you don't waste your money on a curling iron that doesn't work for your hair type. First, we got our one and a fourth inch barrel. This is gonna have that kind of glamorous wave, and it's good for shorter hair, maybe have shoulder length or a little longer. Then we got our one and a half inch barrel. This is great for big bouncy, body full curls, and it's great for longer hair. And then we got our one inch barrel. This one is great for that classic, kind of tighter curl, and it's great for any hair length, but if your hair's very short, maybe try something like this. Otherwise, you won't exactly see too much definition if you use a bigger barrel. It all depends on how lived in versus how styled you want your hair to look. The more lived in, you wanna go with the bigger barrel. The less lived in, you wanna go with this smaller barrel. I hope that helps you figure out what size curling iron to get. And obviously, if the curling iron you find doesn't fit at these exact sizes, then go with something similar to the size I recommend.
