Which area is NOT typically covered in cosmetology training?

Cosmetology training typically encompasses various aspects essential for providing beauty services, including practical skills and theoretical knowledge. Hair coloring techniques are fundamental since they directly relate to a cosmetologist's primary responsibilities. Business management in salons is often included in training programs to prepare future cosmetologists for operating or working in a salon environment effectively, ensuring they understand the commercial side of the industry. Skin anatomy and disorders are also crucial, as understanding the structure and health of the skin is vital for providing skincare treatments and making informed decisions about products used on clients.

On the other hand, the psychology of beauty preferences is generally not a core component of cosmetology training. While understanding client preferences is important for providing good service, the psychological aspects are typically not covered in-depth within standard cosmetology curricula. This area might be touched upon in a broader sense or in specialized courses but is not a primary focus of standard training programs. Thus, it distinguishes itself from the other options, which are integral to the practical application of cosmetology skills.
