Is there a better feeling than walking out of the salon with a freshly-dyed ‘do? We thought not. Whether you’ve opted to lighten, brighten, or darken your hair, newly–colored hair always puts us in a good mood. But what about washing hair after coloring it? Many often wonder: “Should I wash my hair before I color it?” Or, “How long should I wait to wash my hair after coloring?” No one wants to ruin their fresh color because they were too eager to wash their hair.
Ultimately, the goal when looking after dyed hair is to keep your color looking as fresh as possible. Francesca Rapolla, an expert from the Research and Development team at Unilever, weighs in on the topic. “The best way to do this is by using special products formulated for your specific hair color and needs,” she recommends.
So, whether you’ve bleached your hair blonde or are sporting a rich, vibrant hue, there are some universal after-care tips and products you must use. Here’s what you need to know about washing hair after coloring.

How long should you wait to wash your hair after coloring?
As Francesca points out, 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. Phew!
Francesca adds, “There is no specific time you should wait to wash your hair after getting it colored.”
What should you do to keep your hair color from fading?
Contrary to popular belief, sulfates and parabens are not the cause of color-fading. “The worst enemy of color is actually the combination of water and damaged hair. Scientific tests have proven that washing your hair, regardless if the product has sulfates or not, will lead to color fading,” explains Dani De Leon, Unilever’s Research & Development Lead for Hair.
This is because when you color your hair, the hair cuticle, which protects the outer layer of your hair, gets damaged to allow the new hair color to come in. This leaves cracks and gaps on the surface of the hair. When you wash your hair, water seeps through these cracks and gaps and wash away your new hair color, leading to fading.
Therefore, to protect your hair from color-fading, you need to use products that act as a barrier between your colored hair and water. We recommend TRESemmé Pro-Color Series Color Radiance Shampoo and TRESemmé Pro-Color Series Color Radiance Conditioner.
This duo is equipped with an anti-fade, color-lasting technology, which works by creating a waterproof film that coats and binds to your hair fibers to seal in and lock the color in each strand. This way, your hair color lasts for twice longer. TRESemmé Pro-Color Series Color Radiance Shampoo and TRESemmé Pro-Color Series Color Radiance Conditioner also have jojoba oil to keep your hair moisturized and shiny.
How often should you wash your colored hair?
If this is the first time you’ve dyed your locks, you might need to adjust your washing routine. This is to make sure you’re not over-washing your hair. Hair that’s dyed with a lot of pigment can look more faded the more you wash it. If possible, try to only wash it every other day at most, or, ideally every two to three days.
So, should you actually wash your hair before coloring? If you’re bleaching your roots, the answer is no. The natural oils in your hair can actually protect the scalp during the dyeing process. In general though, as Francesca points out, “you should always follow the set instructions of whatever particular dye you are using.” It is also recommended to go to a reputable salon and have professionals handle your dye job with utmost care.
Whatever color you’ve opted for, it’s important to think about your hair texture when creating a washing schedule. Curly hair tends to be drier than other types so if you have dyed your curly hair, it may be best to only wash them once a week.
Fine hair, on the other hand, may need to be washed up to every other day. This is due to the natural buildup of sebum and oils in the hair that can weigh it down and make it appear flat.
Do hot showers make your hair color less vibrant?
Yes, they can. According to Francesca, “hot water opens up the hair cuticle possibly making more color leach out.” In contrast, cold water tends to “seal” the cuticle.
It’s best to simply be aware that the more time you rinse colored hair under hot water, the more it can lose its vibrancy. As such, giving the hair a quick blast of cold water or placing a shower cap over your hair after it’s been washed are two ways to protect colored hair.
