Start by understanding the science of cosmetology — that is, the trichology, chemistry, anatomy, and physiology of the practice. And, before delving into haircutting and styling techniques, coloring principles, and texture treatments, you’ll learn about bacteriology and hygienic salon practices. In your theory studies, you’ll also get familiar with skin and nail basics, which are foundational for hair removal, brow tinting, lash extension, and manicure/pedicure services. You’ll have the required number of core life sciences and cosmetology theory hours met in no time.
