What must a cosmetologist know about hair types?

Understanding different textures and their unique needs for care is crucial for a cosmetologist because hair types vary significantly in terms of their structure, porosity, and density, which all affect how hair responds to various products and treatments. Each hair type—whether straight, wavy, curly, or coily—has specific characteristics that influence its care requirements. For instance, curly hair often requires more moisture and specialized styling techniques to prevent frizz, while straight hair might be more prone to oiliness and may need different types of shampoos and conditioners.

Furthermore, recognizing these differences enables cosmetologists to provide tailored services and advice that enhance the health and appearance of their client's hair. This knowledge plays a vital role in effectively choosing and applying hair care products, styling techniques, and treatments that suit individual needs, thus ensuring client satisfaction and promoting healthy hair practices.
