Don’t worry about any styling products that are left in your hair–they won’t affect the coloring process. If you do wash the day of, lather up with a gentle formula, strong detergents can irritate your scalp. Mix that with the chemicals in dye and you could end up with itching and burning.
You can dye your hair while it’s wet, but the color might be less vibrant, it might not last as long, and it might be a little more uneven than it would be if you colored it while it was dry.
Wash you hair 1-2 days before. Hair should not be excessively dirty, sweaty or oily. Dirty hair does not “grab color better” *see next slide. However, you want there to be a natural protective oil layer on your scalp to act as a barrier against the chemicals in the hair dye.
“After you dye your hair, don’t wash it for at least two days because the hair is still sensitive and therefore will be more like to fade faster,” says Sergio Pattirane, a hairstylist at Rob Peetoom in New York City. “We recommend waiting to wash it so that the color stay fresh and longer.”
Gutkin says to begin applying dye at the roots first, “since the roots need the most color and processing time,” and Rez advises really saturating them with color. “Then, apply dye from the back to the front to ensure the dye is sitting on the back of your hair the longest,” Gutkin says.
no…it’s not advantageous in any way to leave boxed hair colour in overnight. There are several reasons. Boxed dye will ONLY have any effect for 45 to 60 minutes then, “shuts off”. Leaving it on longer will only make a huge mess and do nothing.
Leaving the dye on longer won’t necessarily result in the color being darker or lasting longer. It’s also not a good idea to leave hair dye on skin for longer than recommended. Your scalp may become inflamed and the smell of hair dye may also give you a headache.
