Eyelash Extensions Written Practice Exam

A loose base can be created when an incorrect lash texture is applied on a natural lash typically using a ______ lash.

1. S curve

2. Flat

3. C curve

4. Wavy

The correct answer is: C curve

A loose base is typically formed when an incorrect lash texture is applied to a natural lash, which can compromise the bond between the artificial lash and the natural hair. When considering the option of using a C curve lash, it is important to note that C curve lashes are designed to mimic the natural curvature of most natural lashes, ensuring a balanced and uniform look. By applying a C curve lash, the extension is able to adhere properly to the natural lash and provides the needed support for the extension without creating excessive weight or stress on the root of the natural lash. This alignment helps to maintain the integrity of the lash extension and prevents loosening at the base. In contrast, other textures like flat or S curve lashes may not align as effectively with the natural lash’s architecture, which can lead to improper bonding. A flat lash, while having a wider surface area for adhesive, may cause a mismatch in the natural lash's growth pattern, potentially leading to a loose base as well. Similarly, wavy lashes may not provide the straight alignment needed with natural lash growth, increasing the risk of instability. Thus, using a C curve lash supports optimal adhesion by conforming to the natural lash's shape, reducing the chances of creating a loose base.
