Lash lifts and lash perms are a bit similar, but the process for each is different. Lash lifts literally lift your eyelashes from the base using a speed bump shaped silicone, making your eyelashes appear longer.Meanwhile, lash perming uses a cylindrical rod, which makes it perfect for those who have longer eyelashes. It slightly reduces their length to set up for a beautiful curl. If you're unsure what procedure to get, you can ask your technician for advice.
