When applied correctly, lash extensions will not damage your natural lashes.
The extensions are applied individually to each natural lash. Your lash artist will determine the best weight and length to give you amazing lashes, without damaging your natural lashes.
Your natural lashes are always growing and shedding, you may notice this more when you have eyelash extensions as an extension is easier to see.
Following the correct lash aftercare also ensures that your natural lashes stay healthy and are not damaged.
