How Often Should You Touch Up Grey Roots?

Grey roots usually start showing again within about 14 days.
How often you need to touch up depends on your hair growth and contrast.

How Often to Touch Up Grey Roots

Most people need to touch up grey roots every 14 days.

Factors that affect timing:

  • hair growth speed
  • natural vs coloured hair contrast
  • how quickly grey roots start showing

Why Frequent Full-Head Colouring Is Not Ideal

Colouring your entire hair every time grey roots appear:

  • applies unnecessary chemicals
  • can affect hair condition over time
  • is not needed for small regrowth areas

A Better Approach

Instead of colouring your whole hair, you can:

  • apply colour only where grey roots are showing
  • maintain coverage between full-head colourings
  • reduce unnecessary chemical exposure
