There has been a great resurgence in razor cuts in the past few years, and not since the 1970s has the razor cut been in such high demand by salon clients. Cutting hair with a razor produces a unique textural effect which is difficult to replicate with scissors; however, for best results, one must have the right type of hair for razor cutting.
There are two main qualities which stylists evaluate when deciding whether or not a client's hair is suitable for razor cutting. These qualities are hair density and hair texture. Hair density refers to the total amount of hair on a person's head. This is not to be confused with hair thickness, however, since it is not uncommon for people with fine hair to have high hair density (lots of hair on their head) or for those with thick hair to have low hair density (not a lot of hair on their head). Hair thickness, on the other hand, refers to the thickness of each individual strand. Density simply means the amount of individual hair strands per square inch. Those with high density hair are best suited for razor cuts.
Hair texture is the other quality which determines whether or not a client is suited for a razor cut. Hair comes in many different types of textures, such as straight, wavy, curly, kinky, silky, fine or coarse. A razor cut will look completely different on different textures of hair. As a general rule, razor cuts look best on those with a very slight wave or curl. If hair is too curly, a razor cut will make it look unhealthy and ragged, and if hair is too fine, a razor cut will make the hair look stringy and excessively uneven.
Of course, there are exceptions to every rule. Only a professional stylist who has ample experience cutting hair with a razor can determine whether or not a client's hair is suitable for razor cutting.
