The answer is yes, and indeed it is recommended for those with a particularly long beard. Those with a short beard, on the other hand, will probably have some difficulty using the hair trimmer as a beard trimmer. As we anticipated, the difference between beard trimmer and hair trimmer lies above all in size. The latter in fact has wider blades and uses larger combs. The combs are larger so as to collect the hair strands without problems and the blades are wider as the surface to be shaved is greater on the head than on the face.
