Natural Eyelash Growth Cycle

The two biggest determinants of how long eyelash extensions will last are 1) how well the after care instructions are followed, and 2) the natural eyelash growth cycle. Simply put, the natural eyelash growth cycle is the length of time before an eyelash falls out naturally.

To better understand this, let me briefly explain hair growth in general. Hair
grows in cycles, and each cycle has three phases - growth (anagen), transition (catagen), and resting (telogen). Hair only grows during the first phase, and then it transitions and "rests" until it falls out. The three phases of the hair growth cycle differ in duration depending on body location. For example, hair on your head has a much longer growth phase than your eyelashes do, which is why the hair on your head can grow longer and longer while your eyelashes only grow so long. Once your eyelashes stop growing, they transition to the resting phase where they remain until falling out. While the eyelash is resting, the growth cycle starts over again and the new eyelash pushes the old one out.

Everybody has unique hair growth cycles, and at any given time not all hairs and eyelashes are in the same phase - some are growing while others are resting. In general, I recommend eyelash extension touch-ups every 3 weeks to replace any eyelashes that may have fallen out.
