Unit 2: The Cutting Edge: Haircutting 101

Have you ever wondered how cosmetologists get both sides of a haircut to come out even or know how the layers will shape the final cut? It takes a lot of skill to put it all together and create a polished look. Everything from the shape of the head to the texture of the hair will determine how the hair lies. Learning some classic cuts is a good place to begin, especially since many hair trends are variations of classics. No cut will work well without the proper tools, so be sure to have the right tools for the job on hand!

  • Demonstrate knowledge of the reference points on the head

Unit 3: Barbering Skills

What is the difference between barbering and cosmetology? Barbering focuses exclusively on men and includes specialties like shaving, but creating an attractive hairstyle for men is fundamental to both fields. Fortunately, the same principles of design apply when working with men. In some cases, facial hair can be used to balance the face even further, so be ready to work with a razor! As more and more men prefer old-school shaves, the razor is coming back into mainstream culture. Of course, classic cuts that depend on clippers are not going anywhere, so good clipper skills are an important part of a career in cosmetology. As always, health and safety are key, so proper standards of cleanliness are part of any cosmetology or barbering license.

What will you learn in this unit?

  • Identify haircutting implements
  • Illustrate various haircutting techniques
  • Apply safety in haircutting
  • Recommend hairstyles based on face shape
  • Demonstrate proper sanitation and care of tools
