In 1993 Cornwell invented a special crochet hook that tightly intertwines between 300 and 500 strands of hair. The result: thin locks that represent a celebration of curls and kinks that are easy to style, using curling irons, rollers and styling products, without changing the natural texture of the hair with chemicals.
According to the Boston.com article. Sisterlocks has brought a lot of Black women freedom from their hair, helping them to change their feelings what constitutes good hair. Furthermore, women with Sisterlocks expressed feeling more flexible where their hair is concerned, not rushing to the salon every week and not worried about sweating out their relaxers.
On the Sisterlocks Web site, Cromwell says, "Sisterlocks is much more than a hair care system. It's more like a movement, and it is really powerful!"
