Wahl originally and still do market this shaver/trimmer as designed specifically for a black man who traditionally suffers more from in growing hair. This is down to hair that is more curly than that of a person of white origin who"s hair is generally more straight. However anyone could suffer from in growing hairs and this trimmer is an ideal choice. The trimmer is designed to glide along the surface of the skin, straightening and trimming the hairs as it moves. Due to the design of the blade the cut it gives generally leaves a blunt edge to the hair which is less likely to in grow, hence helping to reduce future occurrence. One thing to hold in mind when considering this shaver is due to its trimmer like blade the shave will not be the closest. It might be worth mixing its use with a more traditional electric shaver using a foil or rotary heads for the best in all round results.
