What is one factor that can affect the choice of hair extensions used?

The choice of hair extensions is significantly influenced by the desired look and style the client wishes to achieve. This factor encompasses not only the overall aesthetics of the extensions, such as color, texture, and volume but also how the extensions will complement the client's facial features and personal style. For instance, a client aiming for a glamorous, voluminous look might choose different extensions compared to someone looking for a more natural, understated appearance. Additionally, understanding the desired style helps stylists recommend the best techniques and types of extensions, ensuring that the final result aligns with the client's expectations.

While other factors, such as cost, length of the client's hair, and potential allergic reactions, are important considerations, they do not directly define the style desired by the client. Cost might influence a client's choice of extensions, and hair length could dictate the type of extension techniques used, but the central aspect driving the selection is ultimately the specific look the client wants to create.
