There are three main reasons you would want to look after them properly:

1. Your eyelash health.
If you regularly do wicked things to them as listed below, it can jeopardize your lash health and slow down the extension of new lashes. Your lids can become itchy from the accumulation of dead skin if they are not cleaned daily.

2. They will look better for longer.
Eyelash extensions that have been coated in mascara, oily makeup and strip lashes don’t look that great.

3. Infill cost and financial/time factors.
If you look after your eyelashes and maintain them well, you won’t need to come in as regularly or for extended infill appointments, which will save you money(Win-Win situation).
