Yes, patch testing is mandatory for both safety and insurance purposes. Patch tests are required for general brow/lash tinting, powder/phi brows, LVL lashes and semi-permanent make-up. The patch test must be done at least 48 hours before any treatments can take place and is valid for 6 months. Although we do understand you may have had a test before at a different salon, we all use different products so have to do our own. No exceptions will be made, and waiver forms are not offered.
