To maintain the flat top ‘look’ you would normally need to visit the hair salon every 2 to 3 weeks, which can become very expensive and time-consuming.

Mid-infrared frequency comb based on a quantum cascade laser. Nature 492, 229–233 (2012).

Hold the t-trimmer with the blade against the skin, and then pull the clipper away at the same angle. First remove the clipper guard. Slide the comb into the hair at whatever angle you desire. It doesn’t have to be a perfect box style cut.

The traditional Topper Comb is about 6 inches wide and better suited for anyone less experienced in cutting hair.

The topper comb must be parallel to the floor and you can use the bubble level to ensure you have the right angle. Always wash and blow dry the hair before you start. That way you’ll achieve a much cleaner/neater cut. Step 2
