Touch-up frequency is one of the most common questions in the salon. It depends on multiple factors: service type, growth rate, gray percentage, and the contrast between applied color and natural base.
All-over color (permanent)
Root touch-ups with permanent dye are needed when the demarcation line becomes visible, typically at 4-6 weeks. Growth of ~1.5 cm per month is enough for the color difference to be evident, especially with high contrast or visible gray.
Highlights and foils
Traditional highlights last longer because the natural root blends between the foils. The typical interval is 8-12 weeks. The finer the highlights and the lower the contrast, the longer the interval can be extended.
Balayage
Balayage is designed to last. With no demarcation line, natural regrowth integrates gradually. Intervals range from 10 to 16 weeks, and in some cases can be extended even further.
Toner and gloss
Toner fades faster than permanent color: 3-5 weeks is typical. Since it is a deposit-only process with no lift, it needs refreshing when the tone loses vibrancy, not when the root grows out.
Factors that shorten touch-up intervals
- Visible gray: Gray at the hairline and temples shows first and may require an early partial touch-up.
- High contrast: Dark over light (or vice versa) makes the root line very noticeable.
- Fast growth: Clients with growth >1.5 cm/month need shorter intervals.
- Frequent washing: Color fades faster with daily washing, especially demi-permanent.
