Which of the following components is part of the aesthetician course curriculum?

The inclusion of eyebrows and lashes in the aesthetician course curriculum is crucial because aestheticians are trained to provide a range of beauty treatments, including services related to the eyes and face. This component covers essential skills such as eyebrow shaping, lash extensions, and tinting, which are foundational services that aestheticians often offer in a salon or spa setting. Mastery in this area allows aestheticians to enhance their clients' natural features, contributing to overall client satisfaction and the aesthetic experience.

In contrast, the focus on makeup theory alone does not encompass the breadth of services provided in aesthetic practice. Hair coloring techniques and barbering fundamentals are also specific to hair services and do not fall under the purview of aesthetic training, which prioritizes skin care and facial aesthetics over hair-related services.
