Lash extensions are certainly all the rage, but there's another lash service that's quickly gaining popularity: Meet the lash lift.

Essentially a perm for your lashes, the service (temporarily) lifts and curls your lashes for a seriously eye-opening effect. Unlike with lash extensions, a lash lift is all you; only your natural lashes are involved.
A lash lift curls your lashes from base to tip so you can see their full length. This service does not add length it adds volume.
The lash tint is a semi-permanent dye that darkens and intensifies the natural color of the hairs. If you're looking at a lash lift service that doesn't come with a tint, consider adding one to maximize the impact you get from the lift.

Not recommended to perform the same day of the wedding and not recommended for sensitive allergic skins. 

Services take around one hour and the lash lift lasts up to four to twelve weeks depending on how oily is your skin and  on how you take care of them.
