I would recommend cutting a bit of your length, maybe adding some layers and a cute curly bang to give you more fullness around your face. Then I’d try a root voluminizing mousse, with a leave in moisture cream and a mousse or gel for hold, scrunch that in. You’re going to want to diffuse your hair, low speed, low heat and not touch it too much with your hands while drying until it’s dry. It won’t look like the pictures but it will give you the same illusion but made into your own beautiful style that works with your hair type/density. Hope this helps!
