The Eyelash Growth Cycle/ Phases

The eyelash growth cycle is essential to understand why it takes months for your eyelashes to grow back, it has three main phases known as the anagen phase, catagen phase, and telogen phase. 

1. The Anagen Phase (Growth)

The first phase of the eyelash growth cycle is known as the anagen phase, every eyelash undergoes this phase to kickstart its growth or regrowth as the case may be. 

This stage takes between 30 – 45 days where the lashes are simply growing, being nourished by the body and its follicles are being stimulated.

2. The Catagen Phase (Transition)

The next phase of growth in this cycle is known as the catagen or transition phase. Here, the lashes stop growing and are most vulnerable as well.

This phase lasts between 2 to 3 weeks and if your lashes are cut or plucked it will take longer than 2 months to grow back because you would need to wait till the cycle restarts. 

3. The Telogen Phase (Resting)

The final stage of the eyelash growth cycle is known as the Telogen or testing phase, by this time, your eyelashes are fully grown and your follicles have shrunk completely.
