Lash Lift gives a semi-permanent curl to the existing natural lashes. The active ingredient in Lash Lift is a perm solution. When performed by a trained specialist and when aftercare instructions are properly followed, your natural lash will not be damaged. Additionally, we treat your lashes with a deep conditioning Keratin treatment which will strengthen your lashes with added nutrients. On average it lasts 4- weeks, depending on your natural lash growth cycle. Eyelash extensions give a more dramatic result.
