During what stage of hair growth should eyelash extensions be avoided?

  1. Telogen

  2. Catagen

  3. Anagen

  4. Resting

The correct answer is: Anagen

Eyelash extensions should be avoided during the anagen stage of hair growth. The anagen phase is when hair is actively growing and is the most optimal stage for hair health and strength. When eyelash extensions are applied at this time, they can put additional stress on actively growing lashes, which may lead to potential damage or premature shedding. Additionally, the natural lashes during this phase are not yet fully matured, and the risk of bonding and maintaining the extensions is lower. In contrast, during the telogen stage, which is the resting phase, lashes are not actively growing and are more stable, making it a safer time for applying extensions. While catagen is a transitional phase where growth ceases and the follicle prepares to shed the lash, it is also better suited for extensions than the active growth phase of anagen. The resting phase allows for a natural cycle, but applying extensions during this time can still pose less risk than during the anagen stage. Therefore, avoiding the application of eyelash extensions during the anagen stage is crucial for ensuring the health and integrity of the natural lashes.
