Each growth phase of the natural eyelashes accounts for what percentage of the lashes on the eye?

1. 10%

2. 20%

3. 30%

4. 40%

The correct answer is: 30%

Each growth phase of the natural eyelashes typically accounts for approximately 30% of the lashes on the eye at any given time. This is important for professionals in the eyelash extension industry to understand because it affects the timing and approach for applying extensions. Natural eyelashes go through three main phases: anagen (growth phase), catagen (transitional phase), and telogen (resting phase). During the anagen phase, eyelashes are actively growing, which contributes to the fullness of the lash line. If a stylist is aware that only a certain percentage of lashes are in the growth phase at any time, they can better plan their application techniques and advise clients on lash care and maintenance. Understanding these percentages also helps in managing client expectations, ensuring that they are aware of how many lashes can realistically support the weight of extensions without risking damage or premature shedding.
