How should eyelash extensions be adjusted if the client has sparse or weak natural lashes?

Using lighter-weight extensions when a client has sparse or weak natural lashes is the preferred approach because it helps to avoid putting excessive stress on the natural lashes, which can lead to damage or breakage. Lighter-weight extensions allow for a more comfortable wear and reduce the risk of pulling or irritating the natural lashes, allowing them to remain healthy.

Applying heavier extensions, on the other hand, could exacerbate the problem, as the added weight might strain the weaker natural lashes. While increasing the number of extensions might seem like a solution, it could result in a similar risk of damage due to the combined weight. Choosing darker-colored extensions may enhance the look, but does not address the underlying condition of the natural lashes and could still lead to stress if the extensions are too heavy. Using lighter-weight extensions is a more mindful approach that supports the integrity of the client's natural lashes.
