#1: TAKE YOUR TIME. PRACTICE PROPER ISOLATION!
Take your time. Practice makes perfect! Practicing proper isolation is what makes a beautiful set. You do not want to disrupt the natural lash growth by clumping them together!
If you damage the eyelashes this could result to (and not limited to the following):
- Lash loss
- Lash hairs not growing back properly
- Discomfort to client's eyes
- Eye irritations
- Redness inside the eye and eyelids
- Extra dry cornea
