Quick answer: Kimage Hair Salon and NK Hairworks lead for precision and customisation. Azel and Jane Salon is the pick for a gentle, formaldehyde-free option that starts at $100. If you want a spa-like reset, SpaJelita and Walking on Sunshine deliver with natural botanicals and a calming atmosphere you can feel the moment you walk in.
You want smooth hair, not an empty wallet. A good keratin treatment is an investment, so ask: does the salon use a formula that protects, or just coats? Is the location convenient enough that you’ll actually go for the touch-up? These picks are the ones where you get real mileage out of every dollar. Choose the salon that fits your hair type, and you’ll spend less time in the chair later.

Singapore’s humidity doesn’t play fair. You walk out of the house with a good hair day and by 11am it is a different story altogether. A proper keratin treatment changes that equation — it cuts styling time in half and keeps the frizz in check, three to five months at a go. The seven salons below each have their own way of doing it. Some lean clinical and precise, others feel more like a quiet retreat. All of them exist to give you back your morning.
Kimage Hair Salon
Kimage is one of those names you hear early when you start asking around, and for good reason. Their signature keratin treatment starts from $370 and is built around an award-winning formula that strengthens the hair while it smooths, so you get the gloss without the limp, just-man-out-of-the-salon look.
They have multiple outlets across Singapore, with Marina Square being an easy central grab if you are killing time between errands. The place runs with a quiet efficiency — stylists who listen, a process that moves without feeling rushed, and operating hours that stretch into the evenings for anyone squeezing in an appointment after work.
Kimage’s signature treatment is a reliable workhorse. This one is for those who don’t want to experiment. Multiple outlets mean you can slot it into your errands. Go on a weekday morning, you’ll be out before lunch. No frills, just hair that behaves.
Address: 6 Raffles Boulevard #02-321/322/323, Singapore 039594 (more branches available)
Phone: 62762700
Hours: Vary by branch; evenings are generally available
Price: From $370
Kimage Hair Salon website
If you are the sort who wants a predictable, polished result and you do not want a long conversation to get it, Kimage is a steady bet. The treatment settles hair that has been through colouring, heat styling, or just years of tropical air, and the texture afterwards is the kind where you can wash and go — shiok, no more wrestling with the blow-dryer every morning.

NK Hairworks
NK Hairworks puts the consultation front and centre. Before a single product touches your hair, a stylist spends time understanding what your hair actually needs — its density, its porosity, how much damage there is to work around. Their Kerasilk keratin treatment starts at $357.50 and bends towards your hair profile rather than applying the same thing to every head that sits down.
The Plaza Singapura branch at 68 Orchard Road is the one most people head to. It is a quick walk from Dhoby Ghaut MRT, and the hours flex around office schedules, which helps when you are booking a two-to-three-hour slot. The formula they use repairs and seals the cuticle in one go, so hair comes out smoother and noticeably shinier — the kind of shine that stays even through a humid week.
If your hair is in a state, don’t anyhow pick a treatment. Here, the stylist checks first, then recommends. That consultation saves you from paying for the wrong thing. The Plaza Singapura branch is central and straightforward. Worth the time if your hair has been through a lot.
Address: 68 Orchard Road, #B1-14, Singapore 238839
Phone: +65 6336 4220
Hours: Flexible; call to confirm
Price: From $357.50
NK Hairworks website
If your hair has been through the wringer — bleached, permed, highlighted — NK Hairworks is worth the trip. They treat the keratin session like a recovery plan, not just a cosmetic upgrade, and you leave with hair that feels stronger, not just sleeker. A good friend once described it as her hair’s “reset button” lah, and that about sums it up.
Azel and Jane Salon
Azel and Jane Salon sits in the heartland at Rivervale Drive but the experience is far from basic. Their formaldehyde-free keratin treatment starts at $100 — the most accessible on this list — and it is made for people who get a bit nervous about harsh chemicals near the scalp. The focus is on nourishing the hair shaft safely, and the shine that follows is genuinely bright without looking artificial.
They have two outlets. The main one at 118 Rivervale Drive opens from 9am to 9pm on Mondays and closes earlier on other days. The Buangkok branch at 275D Compassvale Link has its own rhythm — late Monday evenings and tighter daytime hours the rest of the week. The salon itself is simple and earnest, the sort of place where the stylist remembers your last visit and asks how the hair held up.
Heartland location, no fat price. This is the entry point for anyone nervous about chemicals. You walk in, get the treatment, walk out with shiny hair, and still have money for a good meal. Go on a weekday afternoon, parking is easier. Simple, safe, and your wallet stays happy.
Address: 118 Rivervale Drive, #01-03, Singapore 540118 (Rivervale) / 275D Compassvale Link, #01-05, Singapore 544275 (Buangkok)
Phone: +65 6388 0103 (Rivervale) / +65 6484 0103 (Buangkok)
Hours: Vary by branch; Rivervale 9am–9pm (Mon), 7:30am–5:30pm (Tue–Thu), 9am–6pm (Sat), 9am–5pm (Sun); Buangkok 10:30am–9pm (Mon), 9am–5pm (Tue–Thu), 10am–6pm (Sat), 10am–5pm (Sun)
Price: From $100

This is the salon for a first-timer who wants to try keratin without committing a few hundred dollars, or for anyone with a sensitive scalp who has been putting it off. The treatment is gentle and the results feel like healthy, pampered hair rather than a dramatic restructure — perfect if you still want your hair to feel like your hair, just the version that had a really good week. While you are in the neighbourhood browsing self-care options, our guide to Finest Hair Treatments in Singapore might give you other ideas too.
Picasso Hair Salon
Picasso Hair Salon gives you two clear routes: the Tiboli Keratin Treatment from $325, or the Brazilian Blowout from $280. Both are about smoothing stubborn frizz, but the Brazilian Blowout leans more towards moisturising and a natural-drape finish, while Tiboli targets a sleeker, straighter look. You choose based on how much movement you still want in your hair.
They run two central outlets — one at Goldhill Plaza in Novena and another on North Bridge Road in Bugis. Hours run 11am to 8pm on weekdays and 10am to 7pm on weekends at both locations. Stylists here understand texture across different hair types and they are known for making the result last, so you are not back in the chair six weeks later wondering where the smoothness went.
Two paths, you decide. Tiboli for straighter, Brazilian for more natural flow. This is for those who know exactly what they want. Their central outlets mean you don’t waste time travelling. Just know your hair goal before you walk in, and you’ll leave satisfied.
Address: 1 Goldhill Plaza, #01-49, Singapore 308899 (Novena) / 662 North Bridge Road, #01-00, Singapore 188798 (Bugis)
Phone: +65 6244 0221 (Novena) / +65 6291 0691 (Bugis)
Hours: Mon–Fri 11am–8pm, Sat–Sun 10am–7pm
Price: Tiboli from $325, Brazilian Blowout from $280
Picasso Hair Salon website
Choose Picasso if you are the sort who likes options spelled out clearly and you want a stylist who treats frizz as a puzzle to solve, not just a problem to mask. The Novena outlet is especially convenient if you are already in the area for medical appointments or lunch — book ahead, slot it in, and walk out looking like you just came back from a holiday in cool, dry weather.
SpaJelita
SpaJelita blends a spa environment with keratin restoration in a way that makes the two hours feel like an actual treat, not an errand. Their Keratin Hair Treatment is $220 for the first trial and $258 à la carte thereafter, and the focus is on replenishing natural keratin deep in the hair — the kind of repair that keeps frizz away longer and makes touch-ups less frequent.
The salon is tucked inside Guthrie Building at 150 Changi Road, open daily from 10am to 7pm. It is quiet, unhurried, and people tend to linger in the recovery phase because no one is chasing them out the door. The formulas are built for Singapore’s humidity — the treatment is designed to hold shape and shine through a full commute, not just the air-conditioned car ride home.
If you usually rush through haircare, this one forces you to slow down. The spa setting means the two hours feel like a break, not a chore. First-timer price is sensible — try it once, see how long the smoothness lasts for you. Then you’ll know if it’s worth returning.
Address: 150 Changi Road, #01-02 Guthrie Building, Singapore 419973
Phone: +65 6345 4565
Hours: Daily 10am–7pm
Price: $220 (first trial), $258 à la carte
SpaJelita website
This one suits someone who would book a massage to de-stress and thinks hair health is just another facet of the same ritual. The first-trial price makes it easy to test the waters, and the consistency of the results means you might stop shopping around after that first visit. If you have been browsing Finest Weight Scales in Singapore for your wellness journey, pairing it with a keratin session here feels like the same headspace.
Provocative Hair Couture
Provocative Hair Couture operates out of The Adelphi at Coleman Street, and their Keratin Control Hair Treatment leans on high-grade Italian keratin to de-frizz and fortify. The selling point is protection — the process is designed to guard the hair follicle while it works, so even hair that feels fragile or over-processed comes out stronger, not just straighter.
The salon is open daily 11am to 8pm and contact is direct — WhatsApp or call +65 8784 4825. Inside, it is intimate and precise, the kind of space where the stylist will tell you honestly if your hair needs a trim before the treatment so the result sits properly. The European product line gives it a slightly different feel from some of the more local-oriented salons, and people who colour their hair often say the treatment helps lock in the tone longer.
For hair that’s been coloured, permed, or heated one too many times. The Italian formula is designed to rebuild, not just coat. They’re open every day, so you can fit it into any schedule. A good choice when your hair needs a proper reset.
Address: 1 Coleman Street, #02-19 The Adelphi, Singapore 179803
Phone: +65 8784 4825
Hours: Daily 11am–8pm
Price: Check with the business

This is the stop for someone whose hair has a colour history — balayage, highlights, full bleach — and who needs a keratin treatment that respects that. The Italian keratin is gentler on compromised strands, and the stylists genuinely geek out over getting the texture right. It is a smaller, more personal operation; you will probably talk directly to the person doing your hair before you even book.
Walking on Sunshine
Walking on Sunshine is half salon, half garden café, perched on the third floor of Orchard Central. Their Cinderella Hair Treatment starts from $300 and uses green tea extract and aloe vera for deep hydration and frizz control — a natural formulation that reduces breakage and leaves hair with a soft, just-brushed gloss that lasts between one to three months.
The greenery around you is not a gimmick — it genuinely calms the space, and the chair you sit in faces a wall of plants. Operating hours run Sunday to Friday 10am to 8pm, Saturday 10:30am to 8pm. The treatment itself is a plant-based affair, no formaldehyde, and people who are particular about eco-conscious products gravitate here. You can grab a coffee after and sit among the foliage while your hair settles.
Salon plus café — you can get your hair done and a kopi after. The treatment itself is heavy on natural extracts, so it’s gentle on the scalp. If you want a quiet hideaway in the middle of Orchard, this is the place. The smoothness holds up well for a few months.
Address: 181 Orchard Road, #03-07 Orchard Central, Singapore 238896
Phone: +65 8877 8800
Hours: Sun–Fri 10am–8pm, Sat 10:30am–8pm
Price: From $300
Walking on Sunshine website
Book Walking on Sunshine when you want the keratin treatment to feel like a mini escape, not a chore. It suits anyone who appreciates natural ingredients and a slower pace — and it is a solid pick for a mum who rarely gets a morning to herself and wants to sit somewhere pretty while her hair is being sorted. If you are already mapping out a self-care weekend in town, Finest Halal Cafes in Singapore might point you to a nice lunch spot nearby afterwards.
How to choose
The biggest differentiator is what your hair can handle and what you want from the result. Formaldehyde-free options like Azel and Jane or Walking on Sunshine are kinder on sensitive scalps. If you need heavy-duty repair — hair that has been bleached or heat-styled into submission — NK Hairworks and Provocative Hair Couture spend more time assessing damage and tailoring the formula.
Budget ranges wide here. Azel and Jane Salon starts at $100 and proves you do not need to spend a fortune for a decent keratin finish. At the mid-to-upper end, SpaJelita’s $220 first trial and Kimage’s $370 reflect the depth of consultation, product quality, and how long the result lasts. Ask how many washes the treatment is rated for — several salons will tell you three to five months with proper aftercare, and that matters more than the upfront cost.
Location and vibe matter too. Orchard Central’s lush greenery at Walking on Sunshine is a mood, but if you are strictly about efficiency, Picasso’s Novena outlet or Kimage’s Marina Square location slot neatly into a busy day. Call ahead and ask what shampoo and conditioner you should use afterwards — most salons have a recommended range, and following it is the difference between a three-month result and one that fades in six weeks.
Also consider the time commitment. A keratin treatment typically takes two to three hours in the chair, and some formulations require you to keep your hair completely dry for a day or two afterwards. If you are fitting this around a work schedule, check whether the salon has evening slots — Kimage and NK Hairworks both offer flexible hours that extend past the typical nine-to-five. And if you have a big event coming up, book at least a week ahead so the treatment has time to settle properly.
Hair type plays a role too. Thicker, coarser hair tends to respond well to the more intensive formulas at Picasso or Kimage, while finer hair might only need the lighter touch of a formaldehyde-free treatment at Azel and Jane or Walking on Sunshine. A good stylist will assess this during the consultation and adjust accordingly — which is exactly why NK Hairworks and Provocative Hair Couture put so much weight on that pre-treatment conversation. If you walk in and the stylist skips straight to the product without asking about your hair history, take that as a sign to ask questions yourself.
One last practical note: aftercare products are not just an upsell. The shampoo and conditioner your salon recommends are formulated to work with the keratin bond, and using something too harsh — clarifying shampoos, heavy sulphates — can strip the treatment out in weeks. Factor that into your budget, and stock up before you leave the salon so you are not scrambling later. The investment is worth protecting, especially when Singapore’s humidity is already working against you every day.

Summary
Singapore’s humidity is the real deal, and a good keratin treatment buys you back hours of blow-drying every week. Azel and Jane Salon and Walking on Sunshine give you gentler, plant-based routes at different price points. Kimage, NK Hairworks and Picasso focus on precision and durability. Provocative Hair Couture and SpaJelita each offer a more personal, specialised feel — one for colour-treated hair, the other for a full spa reset. Whichever you choose, the payoff is waking up to hair that behaves, even when the weather does not.

Frequently asked questions
How long does a keratin treatment usually last in Singapore?
Most salons quote between one and five months, depending on the product used and how you care for it at home. Walking on Sunshine, for instance, says their Cinderella Treatment lasts one to three months with proper aftercare.
Is a formaldehyde-free keratin treatment less effective?
Not necessarily. It works differently — more about nourishment and frizz control than straightening at a structural level. Azel and Jane Salon and Walking on Sunshine both use formaldehyde-free formulas that leave hair smooth and healthy, just with a more natural finish.
Can I wash my hair immediately after a keratin treatment?
It varies by salon and product. Some treatments require you to keep hair dry for up to 72 hours. Always ask your stylist for the exact aftercare window and what shampoo they recommend once you can wash.
Which salon is best for badly damaged or colour-treated hair?
NK Hairworks and Provocative Hair Couture both put a lot of emphasis on pre-treatment assessment and tailoring the formula to compromised hair. NK Hairworks uses Kerasilk, and Provocative uses Italian keratin designed to protect fragile strands.
What is the most affordable keratin treatment on this list?
Azel and Jane Salon offers a formaldehyde-free keratin treatment starting at $100, making it the most budget-friendly option. SpaJelita also has a first-trial rate at $220, which is good value if you want a spa environment.
Do these salons need advance booking?
Generally, yes. Keratin treatments take two to three hours, so walk-ins are rarely possible. Call or WhatsApp your preferred salon a few days ahead — Provocative Hair Couture handles bookings directly through their phone line, while larger salons like Kimage have online directories for each branch.
