How Often Should You Touch Up Your Hair Colour?
The honest answer depends on your hair's growth rate and how much contrast there is with your natural colour, not a fixed calendar rule.
Hair-colour touch-up timing depends on regrowth speed, the contrast between the natural and coloured shade, fading, chosen technique and personal preference. There is no universal interval.
Root touch-up
Choose a root service when visible regrowth affects the desired overall appearance.
Global colour refresh
All-over colour may need refreshing when the tone or coverage changes.
Highlights and balayage
Blended placement may create softer regrowth but can still require tone and condition maintenance.
Protect hair condition
Do not repeat chemical colour automatically if the hair feels fragile or has recent bleach, keratin or rebonding history.
Book a consultation when changing direction
Large colour changes, corrections or bleach-based results require a careful plan.
