Abstract
A cutting element for a cutting head for a device for cutting hair is disclosed. A laser beam is directed across a cutting zone, in the cutting head, substantially parallel to a user's skin. The laser beam has an effective cutting region in which the laser beam is of a sufficient intensity to cut hair entering said region. The cutting element has a guard adjacent to the cutting zone to contact a user's skin and space the laser beam there from. The guard has a non-planar shape in a direction extending across the cutting zone so that it substantially follows the contours of an edge of the effective cutting region of the laser beam to reduce any variation in the distance between the edge of the effective cutting region and the user's skin across the length of the cutting zone.
