“How often do I need to come in?” is one of the first questions we get asked at a colour consultation, and the honest answer is that it depends on your hair rather than a fixed rule. Roots become visible for a handful of reasons, and once you understand them, you can predict your own timeline fairly well.
What actually makes regrowth visible
Hair grows at roughly half an inch a month for most people, give or take. That is not fast, but it is not the main factor either — contrast is. A half-inch of natural dark brown regrowth against platinum blonde is obvious within a couple of weeks. The same half-inch of natural brown against a colour just one or two shades lighter barely registers.
- Contrast between your natural base and your applied colour — the bigger the gap, the sooner it shows.
- Grey percentage — grey hair has a different texture and reflects light differently, so even a small amount of regrowth can read as a bright, obvious line.
- Parting and hairline — a centre part or a swept-back style exposes the root sooner than hair that falls forward and covers it.
- How fine or coarse your hair is, which affects how quickly new growth looks like a noticeable band rather than a soft transition.
Realistic ranges by service
These are general ranges, not promises — everyone’s hair and grey coverage is different, and a stylist looking at your actual hair will give you a more precise number.
- Full-coverage single-process colour, especially over grey: most people notice regrowth somewhere between three and five weeks.
- Foiled highlights close to the root: usually six to ten weeks before the line at the parting becomes distracting.
- Balayage: because the lightness is painted to start below the root, many people comfortably go three to five months between full appointments.
If you want more on how those techniques differ in the first place, we cover it in balayage, highlights or foils: what’s actually the difference.
Ways to stretch the gap
If coming in every few weeks does not suit your schedule or budget, there are legitimate ways to buy time between appointments:
- Root shadow or smudge — a soft, deliberately blended tone applied right at the root so the transition looks intentional rather than grown-out.
- Going a little closer to your natural depth — reducing the contrast is the single most effective way to make regrowth less noticeable, and it often means fewer, calmer appointments.
- Adding lowlights — a few darker pieces mixed through can disguise the line where light and dark meet.
- Dry shampoo and a change of parting — genuinely useful, low-cost habits that soften how the root reads day to day.
- Root touch-up sprays or powders — fine as a temporary cosmetic fix for an event or photo, but they sit on top of the hair and wash out; they are not a substitute for an appointment.
When stretching it is not a good idea
Stretching works well when the goal is a soft, low-maintenance grow-out. It works less well when you are covering a high percentage of grey, because grey regrowth tends to show as a sharp, wiry line rather than a gentle gradient, and it can be genuinely bothersome long before it looks “due.” The same is true for anyone whose colour sits at the high-contrast end — very dark base with very light ends, or the reverse.
There is also a cost to stretching too far in the other direction. Repeatedly overlapping colour onto the same mid-lengths and ends, appointment after appointment, builds up product on hair that does not need it — that is what causes banding (visible stripes of different depth down the length) and hair that feels drier and more porous over time. A good colour appointment refreshes the root and only glazes or refreshes the ends where needed, rather than reapplying full-strength colour top to bottom every visit.
Booking ahead
Once you know your own rhythm — three weeks, six weeks, three months — it is worth booking your next appointment before you leave the current one. Colour appointments take real time, and last-minute slots are the hardest to find, especially around holidays. Clients coming from Oak Lawn, Evergreen Park, Chicago Ridge and Burbank tend to book their root touch-ups a few weeks out for exactly this reason.
Keeping up with good aftercare between visits also slows visible fading and keeps the line between old and new colour softer for longer.
