LOreal Professionnel's Hair Touch Up is a temporary root concealer spray enriched with professional pigments that perfectly and instantly conceal grays. The L'Oreal Hair Touch Up is perfect for women to maintain their color in-between salon visits, according to L'Oréal around 42% of women touch up their color at home. The water and sweat-resistant spray is available in multiple shades to help fluently blend with existing color levels 1 through 8 and can be washed out after the first shampooing. Due to high quality and precise nozzle, 

Shake well before each use. Hold the can 4-6 inches away from dry roots. Apply where gray hair regrowth is visible along the part. Spray just enough to cover grays—a little bit goes a long way. If some spray lands on your face, you can easily wipe it off with soap and water. Let roots dry for 1 minute.
