During which phase of hair growth should eyelash extensions be avoided?

Eyelash extensions should be avoided during the anagen phase of hair growth because this is when the hair is actively growing. During the anagen phase, the hair follicles are in a state of significant activity, producing new hair. Attaching eyelash extensions during this time can lead to potential complications such as damage to the natural lashes. As the natural lashes grow, they could also potentially pull on the extensions, resulting in discomfort and premature shedding of both the natural lashes and the extensions.

In contrast, during the telogen phase, hair is in a resting state and is not actively growing, making it a safer time to apply extensions without the risk of interference from new growth. The catagen phase marks a transitional stage when the hair follicle shrinks, but is still stable enough to support extensions. The exogen phase refers to the shedding of hair, which is also not conducive to the application of eyelash extensions. Understanding these growth phases is crucial for maintaining the health of natural lashes while applying extensions safely.
