That colour appointment is still a few weeks out… but those tell-tale roots are right on time. The ultimate MacGyver solution? A few strategic passes of Tint Shot, JOICOs master-in-disguise root concealer that keeps grow-out under lock and key. With a flash-dry formula that’s humidity resistant and four custom-blended shades, this little can of brilliance not only blends the bad stuff in seconds, but actually fills in thinning areas to create the illusion of thicker, fuller hair.
