An eyebrow lamination will last about 6 weeks (again, depending on aftercare). Be sure to follow the “Don’ts” mentioned above in the first 24 hours following your treatment for longevity. In the 48 hours following your treatment, you can apply a hydrating balm or a castor oil to your brows daily. We also recommend brushing your brows in an upright/styled position anytime following a shower (or after getting your brows wet) to help keep their new shape.
