Can you use an eyelash curler on your new extensions? No. Eyelash curlers and heated curlers will damage the lashes. If the correct curl is used there would be no need to curl them again! If you feel you need to curl your lashes, you’ve gone to the wrong place! Straight lashes don’t open the eye like curly ones do. Urban Lash & Tan is best! Book on 0763864793 for your curly lashes now.
