The hair on each person's head is characterized by density, diameter, curl pattern, and porosity. To make things simple, your hair is thicker than normal if a comb snags or gets stuck mid stroke. Hair diameter has four labels in the order of thickness level: Fine, Medium, Thick, and Natural. Fine hair probably has no issues when using a standard plastic comb when doing hair with pomade or other products in it. Medium to Thick hair will experience a static build up and snagging in the middle of a brush or comb stroke when using a plastic comb. A Steeltooth Comb does not produce a static charge nor will it snag creating smooth strokes. This reduces the amount of time it takes to style your hair and removes any limitations you've had previously when it comes to hairstyles. Natural/Coarse hair is normally too thick for plastic combs to even work. People with natural hair usually have to use very coarse brushes with bristles on them, or combs with long metal rods on them.
