Device for treating the hair having two hair treatment jaws that are movable relative to one another between a spaced-apart configuration and a moved-together configuration, an internal treatment member having an internal surface for heating the hair to be treated, which extends over one of the two jaws towards the other in the moved-together configuration of the two jaws and is configured to come into contact with the hair extending between the two jaws in the moved-together configuration thereof, an external treatment member having an external surface for heating the hair to be treated, which extends over one of the jaws towards the exterior of the jaws, one of the jaws having a lateral recess along at least a part of the jaw, the lateral recess facing at least a part of the other jaw and being delimited at least in a proximal and/or distal part of the jaw by a guiding surface.
