It’s the small version and I got it in a size 15 which is one size down from my love bracelet in the size 16 because the juste in clou runs a little bit bigger🫶🏼✨
There are plenty of tutos on the internet. And wavy/curly hair is puffy everytime we don't style it. I'd recommend finding out your hair porosity first and then finding the shampoo & conditioner that suits you best. And as for the styling part, I'd suggest using Brazilian hair care products. Trust me with this, they are cheap and work wonders. All you need is a curl cream, mousse, gel and serum/oil.
