Which factors should influence the choice of lash diameter for extensions?

The choice of lash diameter for extensions primarily hinges on the thickness of the client's natural lashes. When selecting lash extensions, it's crucial to consider the strength and health of the client's natural lashes to avoid causing damage. Thicker extensions may weigh down finer natural lashes, leading to breakage or premature fallout. By matching the diameter of the extensions to the natural lashes, the stylist can ensure that the extensions not only look aesthetically pleasing but also maintain the integrity of the client's natural lashes.

While the desired length of the lashes and the client's age can impact the overall look and suitability of the extensions, they do not directly inform the choice of diameter in the same way the natural lash thickness does. Similarly, the color of the natural lashes is more related to aesthetic preferences than to the structural considerations that dictate the appropriate diameter for safety and durability.
