A rounded haircut with a squarish bottom section is a fun frame for her face and with the blunt cut lower line it has a very distinct and modern character. Once the cut is in place all the of the rest is a walk in the park.
Her naturally curly hair does not need much to look this great, but some smoothing serum, an anti-frizz product and a touch of shine spray will polish up this wild and joyful mane.
