It's highly water-resistant, smudge-proof, and won't stain your pillows. 

Tintation Color Spray offers numerous benefits: it contains no ammonia, requires no bleach, is peroxide-free, highly water-resistant, smudge-proof, enriched with olive oil, pillow-friendly, and dries instantly in just one minute.

For optimal results, use on dry hair. Shake the can vigorously before each application. Hold the can 4-6 inches from your hair and spray evenly; the color intensifies as it dries. Allow 1 minute for the product to set. To remove, simply shampoo your hair and rinse well.
