Quick answer: If your hair sees regular chemical work, start with Kérastase Resistance or Olaplex No.4 for rebuild. For a sulphate-free, peptide-based reset between treatments, K18 hits the spot. Prefer plant-based, eco-friendly? Aveda Damage Remedy or Davines NOUNOU. Fighting frizz on rebonded hair? Shiseido Professional Sleekliner. L’Oréal Professionnel Pro-Keratin does solid fibre repair at a broader price point.
Kérastase
At Chez Vous salon in Ngee Ann City, the go-to for many when rebonding or colour has left hair crying for help. The Resistance Bain Thérapiste shampoo is the one stylists reach for after major chemical services. Its Fibra-Kap Complex works on the keratin-associated proteins – the stuff that keeps strands structured – so hair doesn’t snap three weeks later.
It lathers and coats without that gunky, heavy feeling some repair shampoos leave behind. You use it a couple of times a week, and the difference in how your hair holds a blowout in 90% humidity is why people keep repurchasing.
Where to buy: Chez Vous, 391 Orchard Road, #05-05 Ngee Ann City, Singapore 238872
Phone: +65 6338 7800
Opening: Daily 10am–10pm (kerastase.com)
This one is for you if the salon chair is your second home and you want your treatment to last. Pair it with the matching masque and your stylist might actually notice.

Olaplex
You know that bottle with the numbered system that all the colourists talk about. Olaplex No.4 Bond Maintenance shampoo is what you use at home after they’ve used No.1 and No.2 in the salon. The bis-aminopropyl diglycol dimaleate bonding agent targets the disulphide bonds inside the hair shaft – the ones that break during bleaching and straightening – and stitches them back up.
Most people who double-process their colour use this as their everyday wash because it cleans without stripping, and hair doesn’t stretch like wet elastic. In Singapore’s heat, that means less frizz and a colour that stays vivid longer.
Where to buy: Sephora ION Orchard, 2 Orchard Turn, Singapore 238801 (and all Sephora stores island-wide)

Opening: Typically 10am–10pm daily (olaplex.com)
If you bleach, tone, perm, or just have hair that feels like candy floss after a wash, this rebuilds it from the inside. No heavy silicone film – just bond repair.

K18
The biotech approach to hair. K18’s Peptide Prep pH Maintenance shampoo is sulphate-free and pH-balanced so it preserves the hair’s molecular structure while you cleanse. The real star is the brand’s peptide technology – short chains of amino acids that travel into the inner cortex to reconnect broken keratin chains.
You don’t use it daily; it’s designed to prep your hair for the K18 leave-in mask between chemical services. It also helps with an itchy, flaky scalp because it’s so gentle – a common side benefit people mention after rebonding or heavy colour work.
Where to buy: Sephora ION Orchard and other Sephora outlets, plus salon partners (k18hair.com)
Price signal: Check with store or salon.
Good if your hair is in that in-between state – not fully destroyed, but you know another round of bleach would push it over the edge. The science here is legit, not marketing fluff.
Aveda
The Damage Remedy Restructuring shampoo smells like a spa and works like a repair crew. It runs on certified organic quinoa protein and coconut oils, with zero silicones, so high-porosity, colour-faded hair drinks it up without getting greasy at the roots.
In sunny Singapore, this is the shampoo for the person who reads ingredient labels and wants a daily wash that rebuilds elasticity. Hair feels stronger after a few washes, and the ayurvedic-inspired formula leaves it with a natural, healthy shine rather than a synthetic gloss.
Where to buy: The Shoppes at Marina Bay Sands, #B2-90B, Singapore (more branches across the island)
Phone: +65 6688 7198
Opening: 10am–9pm daily (aveda.com)
If green beauty matters to you but you still want something that actually fixes damage, this is your pick. It’s also kid-friendly – the mild scent and plant-based lather won’t scare a fussy tween.
Davines
Italian, sustainable, and quietly effective. The NOUNOU Shampoo uses tomato extract and plant proteins to nourish overprocessed, bleached hair without turning it into a limp mess. Many people alternate this with a stronger clarifying wash – think of it as the conditioner-heavy reset button when your hair is feeling frazzled.
It restores elasticity, so those fine, fragile strands that snap when you run a brush through them start to hold their own. The brand’s packaging is all recyclable, and the carbon-neutral production matters to a certain kind of buyer who thinks about these things.
Where to buy: @nn salon, 76 Bras Basah Road, Carlton Hotel #04-00, Singapore 189558

Customer care hours: Monday–Friday, 9:30am–5:30pm (davines.com.sg)
Perfect if you like the idea of a salon brand that doesn’t scream “luxury” from the bottle but delivers the same repair. The lightness makes it a decent daily option even in humid months.

Shiseido Professional
Built for Asian hair and our climate. The Sleekliner shampoo gives humidity-resistant thermal protection, so the smooth, straight hair you walked out of the salon with doesn’t puff up by noon. It’s formulated to strengthen fragile strands while taming frizz, making it the obvious choice after a fresh rebonding job.
Local stylists rely on this one because it extends the life of the treatment and keeps the hair looking salon-fresh for weeks. Even on non-rebonded hair, it manages that typical Singapore puffiness without weighing things down.

If your morning routine includes a flat iron and you are tired of the frizz fight by lunch, this is the one to plonk in your shower.
L’Oréal Professionnel
The Serie Expert Pro-Keratin shampoo takes the Pro-Keratin + Incell Complex and goes to work on the internal fibre of the hair, literally rebuilding damaged areas and sealing the cuticle for softness. It’s a workhorse for hair that’s been through straightening, colouring, or bleach-and-tone sessions and now feels weak.
You’ll find it in salons across Singapore, often recommended as the at-home follow-up to a keratin treatment. The softness is noticeable after a single wash, and it keeps hair manageable without that straw-like texture.

Available: Salons island-wide; reach out via their Facebook page for a location near you (lorealprofessionnel.com)
Good all-rounder if you want professional-grade repair but need something more accessible and budget-friendly than some niche lab brands. If your stylist does a lot of bleach-and-tone, this is probably the one they hand you.

How to choose
Think about what your hair has been through recently. Just had a chemical service? Go straight to bond repair: Olaplex No.4 for colour-treated hair that snaps easily, or Kérastase Resistance for deeper keratin reconstruction after rebonding or straightening. In between services, K18’s gentle peptides reset the hair without overloading it.
If chemicals aren’t a big factor but humidity is making a mess, Shiseido Professional Sleekliner gives you thermal and humidity protection that keeps frizz down on straight styles. For a more natural, plant-based route that still repairs damage, Aveda Damage Remedy and Davines NOUNOU both deliver without silicones. L’Oréal Professionnel Pro-Keratin is a solid middle ground – powerful rebuild at a price that doesn’t sting as much as some others.
No standard price tags here; these are salon products, so expect to pay anywhere from $35 to $60+ for a 250ml bottle. Check with the specific salon or store. Most last months because you don’t need much per wash.

Summary
The right salon shampoo basically freezes your hair in its best post-salon state for longer. If you are spending on treatments, skipping a proper homecare shampoo is like buying a silk shirt and washing it with dish soap. Pick one that matches what your hair actually goes through, and your morning routine gets a whole lot easier.
If you are also sorting out your grooming kit, our Finest Facial Washes for Men in Singapore list has the cleansers that work without drying you out.

Frequently asked questions
What’s the difference between salon shampoo and drugstore shampoo?
Salon shampoos use higher concentrations of active ingredients and fewer fillers like heavy silicones that coat the hair without treating it. They are formulated to address specific damage – like broken bonds or keratin loss – rather than just cleaning.
Can I use these shampoos on coloured hair?
Yes, all the shampoos listed are safe for coloured hair, but some are better suited than others. Olaplex and K18 are specifically built to maintain colour-treated or bleach-damaged hair. Aveda Damage Remedy is silicone-free and helps colour last longer.
How often should I use a bond repair shampoo like Olaplex or Kérastase?
For heavily damaged hair, two to three times a week is typical. On other days, you can use a milder hydrating shampoo. K18’s Peptide Prep is often used just before a leave-in mask treatment rather than daily. Listen to how your hair feels – overuse can make it feel heavy.
Are these shampoos suitable for daily use in Singapore’s humidity?
Many are. Davines NOUNOU and Shiseido Professional Sleekliner are light enough for daily washing if you exercise or sweat a lot. Bond-building formulas like Olaplex No.4 can also be used daily but some people find they only need to use them a few times a week.
Where can I buy Kérastase shampoo in Singapore?
You can pick it up at the Chez Vous salon in Ngee Ann City (#05-05, 391 Orchard Road). Ask the stylists there which variant suits your hair; they are familiar with the whole range.
Do I need to use the matching conditioner with these shampoos?
It’s not mandatory, but you’ll get better results. The conditioner from the same line is designed to lock in the shampoo’s repair work and seal the cuticle. If you are already spending on the shampoo, pairing it is worth it for colour-treated or rebonded hair.
