What is covered in the related science hours for cosmetology?

The related science hours for cosmetology encompass critical subjects that underpin the practice of cosmetology, and physiology and histology are essential components. Physiology refers to the study of the functions and processes of the human body, which is fundamental for cosmetologists in understanding how various treatments affect the skin, hair, and nails. Histology, on the other hand, is the microscopic study of tissues, which is crucial for understanding the structure of hair and skin at a cellular level. This knowledge helps cosmetologists make informed decisions regarding the products and techniques they use, ensuring both effectiveness and safety in their services.

The other options, while valuable in their own right, do not cover the scientific principles that are specifically included in related science hours. Health and safety regulations address compliance and standards but do not delve into the biological sciences. Basics of haircoloring focus on techniques rather than the underlying science, and customer service techniques pertain to interpersonal skills rather than the scientific knowledge essential for cosmetology. Understanding physiology and histology equips cosmetologists with the necessary foundation to apply their craft safely and effectively.
