How often should you get a root touch-up? A colorist's honest answer
The answer you'll get from most salons is "every four weeks," which is also — coincidentally — the answer that books the most appointments. Here's the honest version we give clients in the chair.
The real schedule: 5–7 weeks for most people
Hair grows about half an inch a month. For most single-process color, regrowth becomes visible-visible around week five, and by week seven the line is doing the talking. So:
- Covering gray at 50%+: 4–5 weeks. Gray regrowth reads faster because of the contrast.
- Covering scattered gray or going darker: 5–7 weeks.
- Fashion shades and reds: 5–6 weeks — reds fade fastest, so the refresh matters as much as the roots.
- Lived-in or rooted color: 8–12+ weeks. The grow-out is designed in. (This is the low-maintenance cheat code — we wrote a whole post about it.)
The gloss trick that buys you an extra month
A toner/gloss appointment ($50–75 at DH, about 30 minutes) doesn't touch your regrowth — it refreshes the tone of everything else. Faded mids and ends are what make roots look worse than they are. Gloss at week four, touch up at week eight, and your color budget goes further while your hair looks better the entire time.
When you really shouldn't stretch it
If you color over more than an inch of regrowth, the new color can grab differently on the fresh growth versus the previously-colored band — that's how you get "hot roots" or a visible stripe. Past 10–12 weeks, a quick root touch-up sometimes becomes a longer (and pricier) all-over correction. Stretching to week 8 saves money; stretching to week 14 usually doesn't.
What it costs
