The first Kayla doll appeared in 2002, with the Lea doll coming around the same time as a replacement to the Kira doll. They both shared the same face mold yet Kayla had a more prominent appearance in the Cali Girl line,
Her skin usually had a olive complexion and her hair was brown or a auburn shade. Her eyes were often a shade of green or blue. In other editions, Kayla had a fairer tone and red hair, a example of this variation is the 2003 Secret Spells Kayla.
