Device to isolate a lock of hair

Abstract

A device to isolate at least one lock of hair to which a product is to be applied. The device includes first and second sheets each including a first end and a second opposite end. A means of attachment is integral with the first and/or the second sheet, to attach the two sheets together in a reversible manner in proximity to their first ends over the lock of hair that is isolated. The two sheets are configured so as to have their second ends free when they are attached together in proximity to their first end. A process for applying a hair treatment product (such as a coloring and/or decoloring product) is also provided which uses such a device.
