Shaving styles are emerging time and again with advancements in fashion trends. Barbers are working tirelessly to provide quality services that meet the needs of various clients. Quality services need accuracy to make the final design attractive and appealing. Barbers have come up with various methods of making accurate cuts and shaving styles. When a client has chosen his or her hairstyle, the barber applies all the necessary geometry to realize the chosen design. Precision and accuracy is the key. Here, we are going to discuss how geometry is applied in real life situation to make super cuts and outstanding shaving styles.

Barbershops using knowledge in geometry to offer their services have an advanced computerized system with all the designs a client may need. This system has a monitor for display, database at the backend, scanner, microcontroller and high resolution cameras. The monitor displays numerous designs a client can select. Upon selection, the monitor outlines the steps needed for achieving that hairstyle. All the shaving tips are explained in details. Database stores data used for running the system. The stored data elaborates geometrically the procedures to be followed. Scanner and cameras are used to capture images of a client to help in making suggestions of shaving styles that suits his or her head-shape.
Geometry used here involves construction of arcs on client’s head to provide an outline of the area to be shaved. Hand instruments used in this barbershop are protractor, set squares, marker pens, hair comb, shaving machine and compass. A client can select his or her favourite hairstyle from the computerized system. Display monitor has a user-friendly interface with features that are easy to interact with. After he or she has made a selection, the barber will be taken through all the procedures to follow when shaving to come up with the exact look. Alternatively, he or she may decide to scan his or her head to make the system determine the best style suiting the existing head-shape. Microcontroller is notified by the scanner and cameras that images of the client have been captured and need to be taken to the database. It fetches those images and take them for storage in the database. With the instructions from the microcontroller, the scanner scans the image of the client to design the best haircut for him or her. After this process is completed, microcontroller takes the final image of the client to the monitor for display. The final image has the best haircut on it. The barber can go ahead and study the procedures to follow when making that haircut. All the instruments needed during the process are also mentioned.

| Taking geometric measurements |
The shaving is done based on the dimensions given by the system. The dimensions include arc length, angle subtended and the point of origin. For example, if the forehead of the client is supposed to have a haircut resembling an arc, the dimensions will be outlined to make it realistic. The system will explain using the image of the client where the compass will be placed to draw an outline of the haircut. The barber will place a protractor on the client’s forehead to mark an angle the arc will subtend. Erasable marker pen is used to mark the angle. A compass with a marker pen is used to draw the arc joining the points marked earlier. The arc length should match the one given by the system. Shaving machine will be now used to shave the client following strictly the drawn arc. The hair will be reduced to the size shown by the system. Keenness and strictness are very important during shaving process. Perfection relies on the accuracy of the barber when drawing the arc and shaving the hair as explained.

Advantages of this system are as follows:
1. It is accurate. This shaving technique is very accurate compared to normal shaving method. This is because the system gives a detailed procedure on how to do the haircut. All dimensions are explained geometrically to make the process easy to understand.
2. It is reliable. The system provides the best haircut based on the head shape of the client. The client will have a clue on how he or she will look after the shave. It appears more favourable compared to ancient shaving techniques.
Disadvantages of this system are:
1. It is difficult to implement. It requires a good understanding of geometry. Those who are not good in mathematics can find it quite challenging as it involves drawing arcs based on given dimensions.
2. It is expensive. Installing the computerized system needs a lot of money. The system needs a lot of programming and technical expertise.
3. The system needs a backup power supply to keep it on when there is power failure.
Geometric barbershop makes good use of geometry learnt in classwork to real life situation. Although it is time consuming, it provides the best haircut when everything is done with precision.
