Most hairstylists recommend waiting between 24/48 hours ( 1/2 days) washing your hair after a color/toner service. If you can wait until tomorrow it would be better.
In general, Its wise to wait at least 24 hours after coloring to allow the color to set before shampooing, during which any excess color will be washed away. (If you have excess color some may rinse out with warm water as well.) However If you've waited 2 days you should be good to wash.
“I generally tell my clients to wait 48 hours before they wash their hair,” VanDyke says. During the first 48 hours after a color service, the pigments of the salon color are still settling—meaning if you shampoo your hair too soon after an appointment, it can cause your hue to fade quicker.
You're supposed to rinse your hair when the color is done processing (with shampoo), then condition it to close the cuticles in your hair. After you condition, you've completed the last step of dying your hair. So now that you're all done, wait 72 hours until you wash again.
It's good to keep in mind that there are many many reasons that can cause hair color to fade. Some color will fade completely in the first wash, while other color may take weeks to show any signs of fading.
We often get the question: how long do you have to let the hair dye sit before rinsing it out? The answer is, you always have to let the dye sit for at least 35 minutes from the moment you've finished applying all of the dye. After 45 minutes the dye loses it's effect so it's no use letting it sit any longer.
Post-color washing is essential for maintaining the structural integrity of your hair. By cleansing and conditioning, salons help in closing the hair cuticles, locking in moisture, and preserving the smoothness of your locks.
“Some people with dry hair or curly hair can wash much less frequently without problems,” Goh says. For some people, shampooing every other day, or every 2 to 3 days, without washing is fine. Depending on your hair's texture, it's better to go longer between washes.
A good rule of thumb is washing 12-24 hours prior to a hair color visit.
Washing your hair frequently with hot water can also help speed up the fading process. Additionally, exposing your hair to sunlight can naturally lighten the dye.
It's fine to wash it before applying color. Just don't condition it.
Avoid washing your hair for the first 48-72 hours after bleaching it. Give your hair ample time to seal in its new color. Because bleaching is such a volatile process, your cuticles remain open for longer immediately following a bleaching session.
You shouldn't dye your hair twice in one day because this doesn't give your strands enough time to recover between processes.
Once you leave the salon try not to wash your hair for 24-48 hours. This will help prolong the tone of your hair.
Chlorine can leach pigment from coloured hair, causing it to fade and become damaged and brittle. If you really love your colour, make a swim cap your new best friend and avoid swimming for at least a week after your dye job.
In general, you'll want to wait about 24 to 48 hours after dyeing your hair to wash it.
“There was a time when hair color was very harsh and you needed a barrier between it and your skin,” she says. That's not the case anymore: Today, hairstylists generally prefer the hair to be clean before dyeing it.
Leaving the dye on your head too long could make your hair dry and brittle or cause an allergic reaction to the product. In general, hair dyes should stay on for 30-45 minutes max before rinsing out with cool water and shampooing as usual.
According to stylist Rosi Fernandez, director of Ananda Ferdi it is not advisable to go for more than a week without washing hair, as “follicles become clogged and do not get oxygenated,” she explains.
The no-poo (or “no shampoo”) method is a hair-cleansing technique that removes shampoo from the equation, says Yadav. Instead of using shampoo, followers of the practice use alternatives such as apple cider vinegar, a cleansing conditioner, or just plain water.
The general rule of thumb is to not wash your hair the day of coloring or even the day before coloring if your hair washing routine allows. You might hear colorists say a second (or even third) day hair is best.
