How long does root touch-up permanent hair color last?
Permanent root touch-up hair colour lasts until new hair grows. Unlike temporary root touch-up sprays or powders, permanent hair colour does not wash out with shampoo. Grey roots start to show again when new hair grows from the scalp. For many people, visible grey regrowth can appear within 14 days, depending on individual hair growth rates.
How Long Does Permanent Root Touch-Up Last?
Permanent root touch-up hair colour lasts until new hair grows in.
This means:
- The colour does not wash out after shampooing

- Only new regrowth needs to be treated

Why It Lasts Longer Than Temporary Options
Temporary root touch-up products, such as sprays and powders, only coat the surface of the hair.
As a result:
- They wash out after one shampoo
- They require frequent reapplication
- Coverage is short-term
Permanent root touch-up works differently by penetrating the hair, providing deeper, more reliable coverage that lasts.
How Often Do You Need to Reapply?
You don’t need to reapply permanent root touch-up on a fixed schedule.
Instead, you can apply it:
- When grey roots start showing
- Only in the areas that need coverage
- As part of your regular maintenance routine
This gives you more flexibility and control compared to full-head colouring.
A Smarter Way to Maintain Your Colour
One of the biggest advantages of root touch-up permanent hair colour is targeted application.
Instead of colouring your entire hair every few weeks, you can:
- Apply colour only where needed
- Focus on areas like the hairline, part, and temples
- Maintain consistent coverage without over-processing your hair
This approach helps extend the time between full-head colourings.
