As our LVL Lashes treatment launches at Rainbow Room International Beauty in our Royal Exchange Square salon, Head Beautician, Alison gives us the low-down and everything we need to know on the new beauty trend!... As time goes on, we are noticing less and less people opting for eyelash extensions, maybe they like the natural look or something that requires less upkeep! I'm always one of them...having recently tried the LVL lash treatment, I have found the perfect balance. Length, Volume and Lift...all in one treatment.
