Hairchalk - Color Polish by L'Oréal Professional. It's great for adding a little pizazz to your hair! They come in 8 temporary colors that do not rub off on clothing or pillows. Even if you have dark hair, the color is brilliant! Lasts between 2 and 10 shampoos.
Customer review: I absolutely love these!
These are brighter & last longer than the paste type - you can get the color out if you use a cleansing shampoo, & hot water if you want - otherwise, sulfate-free, & cool water to leave it in. It's cool to mix and match it up.
Schwarzkopf also has a new temporary color just for Blondes. The spray-on BLONDME INSTANT BLUSHES are available in four trendy tones; Strawberry (light rose pink), Ice (lilac), Steel blue (light blue with grey undertone), and Jade (seafoam green). The special feature: They stay in for up to three washes, and allows you to experiment with color without the long-term commitment. Use one shade to create a sexy colored ombre, or combine multiple for a technicolor experience.
