I'm always looking for ways to play with pastel tones in the hair. This is the first ever in-shower watercolor that creates a temporary tone when sprayed on wet hair and then rinsed out. The intensity is up to you. When you spray it on damp, towel-dried hair it will soak up more color and last longer. If you spray it on wet hair it will give you a more subtle tone and will rinse out faster. The pink tone is most visible on pre-lightened/highlighted or blonde hair and washes out in 1-3 shampoos depending on the porosity of your hair.
