The best thing to do is to avoid shampooing directly after dyeing your hair. Instead, rinse with cold or lukewarm water to avoid washing the color away.
One of the most important things to remember when it comes to post-dye hair care is that you should always wait at least two full days before washing your hair. Why? Experts recommend waiting this long to give your hair time to properly seal in the new color.
Improper rinsing of hair dye can lead to scalp irritation and damage, which may contribute to hair fall. It's essential to thoroughly rinse the dye out to prevent these issues. However, occasional missed rinses are unlikely to cause significant hair loss.
After dyeing your hair, it's generally recommended to wait at least 48 to 72 hours before washing it. This allows the hair cuticle to fully close and helps the color set better, resulting in longer-lasting color. However, if you used a semi-permanent dye, waiting 24 hours may be sufficient.
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.
If your hair is brown, you may need to bleach it more than once before you apply the grey dye. It's important you get your hair as light as possible before you attempt to turn it grey – this will help ensure a more even tone and vibrant, all-over colour.
ending up with a color that's too dark/too light
They think that if they leave the color in shorter, it'll be lighter. And conversely, if they leave the color in longer, it'll be darker. But just like filling up a cup of coffee, the fuller the cup, the longer the color will stay in your hair.
Color will fade even without washing it. Oil from your scalp can pull hair color out, or it can even rub off on your pillowcase!
Don't shampoo immediately before dyeing your hair. Why? Because 1-2 days unwashed hair has a protective barrier on the scalp - it means there's less chance of any irritation and color pigment is better deposited. Also, just before dyeing, avoid using styling products (dry shampoo, hair spray, gels etc.).
**Stylist Preference**: Stylists prefer working with clean hair because it allows them to better assess the natural color and condition of your hair.
Use a clarifying shampoo
If you need to remove hair dye fast, reach for a clarifying or anti-dandruff shampoo. These are like a deep cleanse for your hair. The harsh chemicals in these shampoos will strip your hair of color. They work by stripping away not just dirt and oil, but also any unwanted hair dye.
Condition your hair right after dyeing.
Usually, a packet of conditioner comes with the dye product. If there's not, use your usual conditioner, leave it in for at least three minutes, then rinse with cool water. If you had your dye job done professionally, consider booking a conditioning treatment afterward.
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.
Pick a lighter hair colour
A lighter colour will then look better. Your hair follicles produce less pigment as you're turning older. If there's no more pigment being produced in the hair follicles, your hair turns pigmentless.
To avoid it going ginger or red then you must check what shade you are using. For example if the colour says golden, chocolate, mahogany, red, warm brown etc, these will all look 'ginger'. To achieve a rich colour, a basic shade must be added to create the depth (how dark it is).
It could be that your hair is resistant to tint, especially when the hair texture has changed as a result of going white. But also it could be that by going lighter, either all over, or by introducing (subtle) highlights you would not see the regrowth strip quite as quickly as if it were lighter.
Put simply, your client should wait as long as they can before washing their freshly colored hair, as this allows the cuticles to fully close up and seal in their dream shade. For some, this could be 48 hours, while others may be able to hold on for up to one week.
One way to make your hair colour look more natural is to blend different tones together. This can be done by using two different shades of the same colour or by mixing a light shade with a dark shade. Experiment with blending your own colours and highlighting small sections to get a more natural effect.
I Dyed My Hair and Now It Feels Like Straw
For the color to set permanently, it must get through the hair's natural defenses. Commercial hair dyes use ammonia to lift the layers of the cuticle, so the color can penetrate and take effect.

There's a reason your hair stays fresh for so long after a trip to the salon, and it's probably because the stylist works the shampoo through your hair, scrubbing your scalp and ensuring not to miss an inch.
"If hair isn't washed after being colored, the color products can be left sitting on your scalp, which can get irritated," says Gandolfo. "It also may make your hair feel greasy and heavy."
