Famous sisters

Beauty evolution, sister status.

Having a sister can make you happier and more optimistic, according to a study. And as a celebrity, it’s very beneficial to have someone who understands you deeply. There are pairs of sisters who jumped into the spotlight and became famous both as sisters and individually as well. Their talent and support for each other make them very noticeable in the media.

Of course, it was their biggest champion, hairstylist Mark Townsend, who noticed and announced the irons' reemergence on Instagram yesterday. (Townsend is the longtime stylist of Mary-Kate and Ashley Olsen, and swears up and down the Rsession irons are the secret behind their impossibly piece-y, undone waves.)
