With some brands, you can expect them to last anywhere from 6 – 8 washes, but with products like L'Oréal Paris Casting Crème Gloss, you can enjoy your new colour for up to 28 shampoos. Casting Crème Gloss doesn't just last longer – it also gives you a richer tone that blends grey hairs with your natural highlights.
As the dye stays near the surface of the strand, it usually fades within 12 washes – although darker colors like blue and black may last longer. The final color depends on your natural shade and hair porosity, resulting in a natural, shimmering look.
It mostly has to do with the type of color you have applied, your hair's overall health, and how you care for it. Depending on the type of hair color that your colorist uses on you (ie. Permanent, semi or demi-permanent, or temporary color) it can last in your hair for anywhere from 6-30 washes.
The hair grows about half an inch each month therefore we suggest re-coloring every 4-6 weeks. Unless you are coloring virgin hair or have not colored your hair in over 5 months make sure to follow the touch up application timing for best results.
Permanent hair color is the best long-lasting hair color option as it doesn't wash off. It is usually used when you want to lighten or darken your hair. If you are looking to cover your greys or opt for a global color, it is best to choose a permanent hair color shade.
If you're using a hair bleach like the L'Oréal Paris Feria Hyper Platinum Advanced Lightening System Bleach, you'll want to wait at least 14 days between sessions. That being said, to avoid bleach damaged hair, keep those dye jobs to a minimum for the sake of your hair's health.
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.
You might be wondering if you can keep it in longer than recommended. The answer is yes, but it's not a good idea. Leaving the dye on your head too long could make your hair dry and brittle or cause an allergic reaction to the product.
Wash your hair less often
We're not telling you to skip out on showers completely, but the more you shampoo, the more you rinse or fade out your color. So try to limit your hair washes to a couple of times a week and wait at least 24 hours before shampooing your hair for the first time post-color.
As a general rule of thumb, darker colors tend to stay on the hair for longer. So, if you're adding lowlights, a root shadow or all-over depth, the shade will offer more mileage than, for example, light blondes, light browns or light reds. The same goes for pastel colors versus rainbow colors.
Color That Lasts
Hot water can strip away color faster, leading to more frequent salon visits (and we know those aren't cheap!). Cold water helps keep your color vibrant for longer, saving you time and money.
A semi-permanent color generally fades over time, usually after four to twelve washes. However, it is unlikely that the color will completely wash out, especially if you have used a darker shade. If your hair has been dyed for a long time or if it is porous, some color pigments may remain.

The length of time that permanent hair dye will last depends on a few different factors, including the health of your hair, how often you wash it, what shampoo you use, and the type of hair dye you use. Generally speaking, though, you can expect permanent hair dye to last anywhere from 6 to 12 weeks.
With some brands, you can expect them to last anywhere from 6 – 8 washes, but with products like L'Oréal Paris Casting Crème Gloss, you can enjoy your new colour for up to 28 shampoos. Casting Crème Gloss doesn't just last longer – it also gives you a richer tone that blends grey hairs with your natural highlights.
Apply color to your roots first. Hair that's been previously colored is porous and soaks up color easily, but new growth requires more processing time. Leave color on your roots for the full time and only process ends for half the required time. It'll give you a nice even color from root to tip.
The One-Hour Rule for Mixed Dye
⏳ Once you've mixed it with the developer, aim to use the magic potion within an hour.
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.
Yes, hair should be conditioned after haircolor, but it's better to condition the hair after the color is rinsed and before the shampoo.
A good rule of thumb is washing 12-24 hours prior to a hair color visit.
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.
How often should I dye my hair to cover grey hair? This depends on how quickly your hair grows, but often is between 4-8 weeks. If you're only just starting to grey, it may not be time to begin permanently colouring your hair.
