Avoid Washing for 48 Hours
“If you wash it before then, there's a chance the color will fade,” Renegar warns. It also goes without saying that you should avoid getting hair wet in hot tubs or pools, which is even worse!
"After having your hair colored, wait a full 72 hours before shampooing," says Eva Scrivo, a hairstylist in New York City. "It takes up to three days for the cuticle layer to fully close, which traps the color molecule, allowing for longer lasting hair color."
When Should You Wash Your Hair After Coloring? For any hair type that receives a hair color treatment, it is best to wait at least 72 hours before washing your hair. This way, hair cuticles can have more time to seal in color and prevent it from bleeding out or washing out too quickly.
When To Use Purple Shampoo After Bleaching? Avoid washing your mane for the first 48 to 72 hours after bleaching it. This is to give your hair enough time to seal in its new color. If you waited 72 hours before washing your hair after it was bleached, you could use the purple shampoo the next time you shower.
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.
Hair color needs at least 48 hours to settle into the hair strands. So, if you wash your hair 24 hours after highlighting, the color will quickly wash away and become dull.
Izquierdo says to wait three days. “This gives time for the cuticle to close and the color to set,” he says. That's why you might want to skip a workout or two so you don't have to wet it or wash it—if you do, you're lifting the color right out of your hair.
After the initial dye appointment, wait at least 24 hours before you wash your hair to allow the hair color settle into the hair shaft. If you must wash your hair, run your scalp under cool water and scrub with your fingertips. No, this won't give you a soapy lather, but it will give you that just-cleaned feeling.
Make sure that you give your hair enough time to dry before bedtime. If you must go to sleep while your hair is still wet, braid it first. Don't pull your hair into a bun or ponytail before going to sleep, even when it is dry. This will damage your hair further.
"Experts advise waiting at least 2 weeks (technically 15 days) before dyeing it again.
Because the outer cuticle has been penetrated by the dye, the natural oil of your hair, known as sebum, doesn't travel down the strand.
As a general rule, hair color lasts about 6-8 weeks, depending on if you're covering gray hair or not. If you don't have a lot of gray and you're dying your hair to change up your color, there are ways for stylists to blend in highlights with your natural hair color to keep it looking fresh for longer.
Shampoo Your Color-Treated Hair Less Frequently
– To prevent water from washing away your vibrant color, the answer is simple: Wash your hair less often. To retain those natural oils that help condition your color-treated hair, shampoo just two or three times per week, and never more than every other day.
There's two reasons why your hair is still brassy after toning or colouring. Either the undertone of the toner/colour is wrong, or the product is too light for you.
This is were the over using it can cause problems. "You want to stop using it two weeks before any lightening service. The purple shampoo can cause build up making the hair look dull and darker if overused." This makes the lightening process more difficult to create a seamless blend.
Does Purple Shampoo Make Your Hair Lighter? Purple shampoo is for already bleached hair, so if you're hoping to lighten brown hair with purple shampoo, you'll be disappointed. This is all down to the fact that purple shampoo isn't lightening.
That said, don't leave the product in for longer than 45 minutes. As for semi-permanent dyes, the color will get darker the longer you leave it, but never lighter because direct dyes can't lift pigments.
As a result, colorists recommend washing the hair to remove the grime before coloring, because the excess buildup might result in an uneven dye job. The best way is to wait for at least 24 hours after washing before dyeing your hair.
Your hair will usually be washed as part of the dyeing process, so if possible, don't re-wash it as soon as you get home. However, if you do have to jump in the shower ASAP, it won't make an impact on the vibrancy of your color.
While stylists generally recommend skipping a few washes a week to achieve healthier hair, you might need to scrub it prior to your colorist appointment so your stylist can get an accurate look at your hair's natural color and texture. The same applies for darker tones.
