For clients with thick, coarse, or unruly brows, we suggest trying out the Thuya Brow Pre-Smoother. This treatment is specifically formulated to soften unruly brow hairs, making them easier to manage during the Thuya Brow Lamination process. To apply, just use a cotton swab or Q-tip to apply the Thuya Brow Pre-Smoothing Treatment to the brow hairs. Leave it on for 2-4 minutes, then remove the product using a dry cotton swab or Q-tip before moving on to step 1 of the Thuya permanent gel application.
