COSM 130 - Hair Care

This course offers an in depth look at the elements and principles of hair design, including face shapes, and designing styles accordingly. Shampooing is discussed in detail with focus on scalp manipulations and proper shampoo procedures. Learners will gain applied knowledge in haircutting angles, elevations, guidelines, proper use of tools, four basic hairstyling principles, and procedures for wet styling and blow-dry styling. Learners will also practice styling long hair, thermal styling, hard and soft pressing, braiding with and without extensions, and using wigs, hairpieces, and hair enhancements. Chemical texture services will be analyzed and students will recognize the physical and chemical actions that occur in permanent waving and hair relaxing, as well as the numerous wrapping procedures used in permanent waving and colour theory formulation.
