They solve different problems, and they stack beautifully together.
Tint is colour. Dye is brushed through the brows to darken and define them, filling sparse gaps and making the natural shape read more strongly. It fades over a few weeks, sooner on skin than on the hair.
Lamination is shape. A lifting cream softens the brow hairs just enough to brush them upward and set them there with a neutraliser, rather like a perm for the brows. The result is a brushed-up, fuller-looking brow that stays put through washing and workouts, and grows out over roughly six weeks.
In short: tint answers “my brows are too fair”, lamination answers “my brows won’t behave”. Plenty of clients have both in one appointment, lamination for the set shape, tint for depth.
Both are quick, and tint requires a patch test beforehand because it is a colour service. See the brow lamination page or book.
