When shaping the enhancement on the free edge, which portion of the brush should be used?

• A. The tip of the brush
• B. The middle portion of the brush
• C. The base of the brush
• D. The entire brush surface

Answer: (B)

Using the middle portion of the brush when shaping the enhancement on the free edge is essential for achieving the desired control and precision. The middle part of the brush allows for a balanced application of product, enabling the technician to create smooth and even lines as well as to define the shape of the enhancement effectively. This technique helps in managing the thickness and contour of the enhancement, contributing to a professional-looking finish.

When shaping, utilizing just the tip may restrict control and lead to uneven application, while using the base could result in an undesirable application area and thickness. Employing the entire brush surface might lead to insufficient detailing and can make precision shaping more challenging. Therefore, focusing on the middle portion of the brush provides the ideal balance needed to apply the product effectively on the free edge.
