If you want to buy a spray or have already bought one, you should definitely know that every product can have its drawbacks if not used correctly. New hair cosmetics that cover gray hair in between hair coloring are perfect for immediate use. Sprays are water-resistant. They are washed off from hair and skin with shampoo.

We recommend spraying a very thin layer on your hair and only where the hair growth is visible. If you spray too much spray on your hair and overdo it, the particles of color pigments will not stick to the hair only. When you then put your fingers in your hair, it will get dirty. Likewise, if you put a cap or headband on your head, it will be dirty. You can avoid the inconvenience of loose pigments by lightly combing the sprayed hair with a brush after it dries or by lightly wiping it with a dark towel or paper towel. You can also spray your hair with hairspray.
What should have stuck will stick to your hair and the rest will remain on your brush or towel, napkin. Definitely don’t wear a light-colored hat on your head (it won’t be visible on a dark one). And if you don’t want a dirty pillow, wipe the growths off with a towel before going to bed.
Any dirty pieces of clothing or linen can be washed with regular laundry detergent.
