The consensus among experts is that eyebrow tinting will last between three to eight weeks. Factors in how long your tinting will last include: the type of dye. how hard you scrub your face. 

Tinting will immediately make brows appear thicker. Tinting enhances your brows, at least temporarily (it lasts about a month—and even up to six weeks if you're lucky). It gives brows a more natural look (versus using a makeup pencil to fill brows).

Although it's not a problem to get your eyebrows wet after a tinting treatment, you can try to avoid washing for at least 12 hours. You should also avoid excessive touching or rubbing for 24 hours to avoid irritation.
