Lash tinting is a gentle dyeing treatment for your eyelashes. Unlike a lash lift or lash extensions, you won't get any extra volume. You will, however, get a darker, semi-permanent colouring to improve the look of your lashes. Eyebrow tinting, much like lash tinting, is the careful dyeing of your eyebrows. This is particularly suited to you if you have sparse brows or lighter brows, as the treatment will give you a much more defined pair of brows in the end.
