Swappable head #1, Barbie Fashionistas Swappin' Styles Artsy, and swappable head #2
Found at Target, the second swappable head for Barbie Swappin' Styles Fashionistas Artsy has curly hair that is darker than swappable head #1. Head #2 also differs distinctly from the original head in color and texture.
Head swapping, illustrated:
Artsy has a button on her back which releases her head and the entire breast plate.
Artsy's original head has been popped off.
Head #2 (on the right) is on her body. The original head is placed nearby for comparison. Swappable head #1 is still in the box... it's too much like the original head.

Different is definitely better.
