Locks Lash extensions are beautifully crafted synthetic or silk lashes. They have a seductive flick of the tail with a soft feather light feel. One eyelash extension is bonded with a premium eyelashes extension adhesive to one of your own natural lashes. This attachment is repeated right across your lash line until you are left with a totally natural enhancement of gorgeous lashes. Locks Lash extensions will add length, dramatic color & density to your own lash line. These lashes can last from 4-6 weeks.
