Root Touch-Up in Singapore: How Often, Cost and What to Expect (2026)
A root touch-up recolours only the new growth at your roots, and most people with coloured hair need one every four to eight weeks, depending on how much their colour contrasts with their natural shade. In Singapore, a salon root touch-up typically costs $85 to $135, and the appointment usually takes about an hour to 90 minutes.
That’s the quick version. The longer one depends on what you’re maintaining. A soft brown a shade off your natural colour can go two months or more between visits. Bleached blonde on dark hair starts showing a stripe within weeks, and it needs a very different kind of touch-up.

This guide covers the regrowth side of things: what “1 inch” actually means on a salon menu, how often to book for your type of colour, what happens in the chair, what it costs, and when a full colour makes more sense.
What a Root Touch-Up Actually Is
As your hair grows, the new section at the scalp comes in your natural colour. A root touch-up (also called a root retouch, roots-only colour or regrowth colour) applies colour to that new growth only, matching it to the colour already on your lengths so the line disappears.
The key word is only. The lengths aren’t recoloured, which is why a touch-up is quicker and cheaper than a full head, and why it’s kinder to hair that’s already been coloured several times.
What “1 inch” means on a salon menu
Many Singapore menus price a root touch-up for “up to 1 inch” (about 2.5 cm) of regrowth. Hair grows roughly 1 cm a month, so an inch is about two to two and a half months of growth. If you’ve waited longer, expect the salon to charge more or quote you for a full colour, because there’s simply more hair to cover.
If you colour for contrast, you’ll likely book well before you hit that inch. The menu limit is a price cap, not a target.
Root Touch-Ups by Type of Colour
Not every touch-up is the same job. Here’s how it changes with what’s on your head. (Covering greys? That’s its own topic, and we’ve covered it in grey hair coverage by budget.)
Colour close to your natural shade. A brown or dark brown one or two shades off your own is the easiest to maintain. The regrowth blends in, so you can often stretch to eight weeks or more.
Fashion colour (red, copper, ash, burgundy). The root touch-up covers regrowth, but these shades also fade on the lengths. Many colourists pair the retouch with a gloss or toner through the ends so the root isn’t brighter than the rest.
Dark to light (brown to caramel, light brown or blonde). Lifting your natural dark base needs a lightening colour, and the contrast shows quickly. Four to six weeks is a common rhythm.
Bleach regrowth (platinum, ash blonde, pastels). This is the most technical touch-up. The colourist applies lightener to the new growth only, keeping it off the already-bleached hair. Overlapping bleach onto previously lightened lengths is one of the main causes of breakage, so precision matters more than speed. Most people then need a toner to match the new roots to the ends. If you’ve bleached on top of darker hair, don’t let the regrowth get too long: an even lift is harder to achieve over a wide band.
If your colour is dimensional (balayage or foils), you probably aren’t booking root touch-ups at all. Balayage grows out softly by design, and foil highlights are refreshed with a partial set of foils instead. Our highlights guide covers that maintenance route.
How Often Should You Get a Root Touch-Up?
The honest answer is: when the contrast bothers you. As a rule of thumb, though:
| Your colour | How visible regrowth is | Typical gap between touch-ups |
|---|---|---|
| Within 1 to 2 shades of natural | Low | 6 to 10 weeks |
| Fashion colour (reds, coppers) | Medium, plus fading | 5 to 8 weeks, often with a gloss |
| Dark to light | High | 4 to 6 weeks |
| Bleached or platinum on dark hair | Very high | 4 to 6 weeks |
These are common colourist guidelines, not rules. Two things stretch the gap: choosing a shade closer to your natural base, and styling a zig-zag or shifted parting while you wait. Two things shorten it: very dark natural hair under very light colour, and a sleek centre parting that shows every millimetre.
What Happens in the Chair
Plan for about an hour to 90 minutes for a standard retouch, and longer for a bleach retouch with a toner.
1. Consultation (5 to 10 min). Your colourist checks the regrowth, the condition of your lengths, and whether the ends need a refresh too. Bring up any scalp sensitivity or past reactions here.
2. Sectioning and application (20 to 30 min). Colour or lightener goes onto the new growth only, in fine sections, starting where the hair is most resistant.
3. Processing (30 to 45 min). The colour develops. Some colourists pull colour through the ends for the last few minutes if they’ve faded.
4. Rinse, toner if needed, and blow-dry (15 to 30 min).
If you can still see a line after the blow-dry, say so before you pay: a good salon would rather fix it on the spot.
How Much Does a Root Touch-Up Cost in Singapore?
Across 20 Singapore salon menus in our marketplace research, root touch-ups (about 1 inch of regrowth) have a median price of about $100. Most sit between $85 and $135, with budget options from about $65.
For comparison, full-head single-tone colour on 31 menus has a median entry price of about $120, and long hair typically adds $20 to $40 per length step. So on short hair, a touch-up saves you roughly $20 a visit. The real saving is on long hair, where the gap widens with every length step, and on your hair’s condition, since your lengths aren’t being recoloured each time.
What pushes the price up: lightening or bleach on the regrowth, a toner or gloss on the lengths, ammonia-free colour, a senior colourist, and regrowth beyond the menu’s inch.
Over a year, it adds up. At about $100 a visit, touching up every six weeks is around $850 a year, and every eight weeks is about $650. That’s why picking a shade closer to your natural base is the single biggest money-saver.

Root Touch-Up vs Full Colour: Which Do You Need?
Book a root touch-up if your lengths still look like the colour you chose and only the regrowth gives it away.
Book a full colour if:
- Your lengths have faded or turned brassy and a root-only job would leave the roots brighter than the ends
- You want to change your shade, even slightly
- Your regrowth is well past the inch, or you’ve let it grow out unevenly with a few home attempts in the mix
- You’ve got banding (stripes of different tones from past touch-ups that didn’t quite match)
A lot of salons offer a middle option: a root touch-up plus a gloss or colour pulled through the ends. It costs less than a full colour and refreshes your tone without fully recolouring. Ask for it by name.
At-Home Root Colour vs Salon
Box dye on your roots is tempting at $100 a salon visit. It can work for one situation: a single shade close to your natural colour, no bleach, and you’re comfortable doing it neatly.
It gets risky when:
- You overlap onto your lengths. Repeatedly dyeing hair that’s already coloured builds up darker, duller bands that are hard to fix.
- You’re matching bleached or lightened hair. Home lightener on regrowth is a common route to breakage and uneven, orange roots.
- The shade doesn’t match. A box shade rarely matches a salon formula exactly, so a two-tone result often means a salon colour correction later, which costs far more than the touch-up would have.
Whichever route you pick, do a patch test first. Hair dyes can contain ingredients like PPD (para-phenylenediamine) that some people react to, and a reaction can happen even with a brand you’ve used before. At a salon, mention any previous reaction and ask for a test.
In Singapore, hair dyes are regulated as cosmetic products by the Health Sciences Authority, which covers ingredient and labelling rules for anything applied to the hair to change its appearance.
Making Your Touch-Up Last Longer
- Wait a day or two before the first wash, and use lukewarm water.
- Switch to a sulphate-free, colour-safe shampoo. Harsh cleansers strip colour faster, which makes the root look out of step with the ends sooner.
- Use heat protectant, and keep irons and dryers at moderate temperatures.
- Protect your hair outdoors. Singapore’s sun fades colour, especially reds and lightened tones.
- If you’ve lightened, use a purple shampoo once a week or so to keep brassiness down.
- Book your next visit before you leave. Hitting your rhythm is easier than rescuing overgrown roots.
Is a Root Touch-Up Worth It?
Yes, for almost anyone who wears permanent colour and wants to keep it. It’s the cheapest and gentlest way to hold one colour for months, and it protects your lengths from being recoloured again and again.
Two myths to clear up:
- “A touch-up damages your hair as much as a full colour.” It doesn’t need to. Only the new growth is processed, which is exactly the point.
- “You can just colour over everything each time to keep it even.” Recolouring the full length every visit is what causes build-up and dryness. Colour the roots, and refresh the ends with a gloss only when they need it.
If you find yourself booking every four weeks and resenting it, talk to your colourist about a shade closer to your natural base, or about switching to balayage, which grows out softly.
Frequently Asked Questions
How often should I get a root touch-up?
Most people with coloured hair book a root touch-up every four to eight weeks. Colour within one or two shades of your natural base can often stretch to six to ten weeks, while dark-to-light colour and bleached or platinum hair on a dark base usually needs a touch-up every four to six weeks.
How much is a root touch-up in Singapore?
Across the 20 Singapore salon menus we reviewed, root touch-ups for about 1 inch of regrowth have a median price of about $100, with most between $85 and $135 and budget options from about $65. Lightening, a toner or gloss, ammonia-free colour and longer regrowth all push the price up.
What does “1 inch regrowth” mean for a root touch-up?
It means the salon’s touch-up price covers up to about 2.5 cm of new growth at your roots. Hair grows roughly 1 cm a month, so that is about two to two and a half months of growth. Longer regrowth usually costs more or is quoted as a full colour.
Should I get a root touch-up or a full colour?
Get a root touch-up if your lengths still look like your chosen colour and only the regrowth shows. Choose a full colour if your ends have faded or turned brassy, you want a new shade, or your regrowth is well past an inch. A touch-up plus gloss sits in between.
Can I do my root touch-up at home?
You can if your colour is a single shade close to your natural base, with no bleach, and you can apply it neatly. It is risky over bleached or lightened hair, where home lightener can cause breakage and uneven roots. Always patch test first, as dyes can contain PPD.
