Singapore's humidity sits at 80 to 90 percent year-round. For a large portion of the population, whether your hair is naturally frizzy, colour-treated, curly, or simply fine and prone to puffing up the moment you step outside, that is not a weather statistic. It is a daily battle.
Smoothing treatments have become one of the most requested services at hair salons across Singapore, and for good reason. But not all smoothing treatments are the same. If you have been searching for options, you have probably come across Cezanne and likely had a few questions. This post answers all of them.
What Is a Semi-Permanent Hair Smoothing Treatment?
A semi-permanent hair smoothing treatment is a salon service that reduces frizz, adds shine, and makes hair more manageable, without permanently altering your hair's natural structure. Unlike chemical rebonding or Japanese straightening, which break down and rebuild the hair's bonds to force it straight, a smoothing treatment works with your existing texture rather than against it.
The result is not pin-straight hair. It is your hair, but calmer. Softer. Shinier. Easier to style. And significantly more resistant to humidity.
Semi-permanent smoothing treatments typically last between three and five months depending on hair type, aftercare, and how frequently hair is washed. They sit in a different category from permanent straightening entirely, think of them as a long-term conditioning treatment that happens to also tame frizz.
What Is the Cezanne Keratin Smoothing Treatment?
Cezanne is a professional keratin smoothing treatment that is 100 percent formaldehyde-free. It works by infusing the hair shaft with keratin, the same protein hair is made of, along with silk proteins, argan kernel oil, olive fruit oil, B vitamins, and botanical extracts. Together, these ingredients restore damaged bonds, seal the hair cuticle, and smooth the surface of each strand from the inside out.
The treatment is applied in sections from the nape upward, processed, rinsed, and then sealed with a blowdry and flat iron. From start to finish, the Classic treatment takes approximately 90 minutes. There is no downtime, unlike older keratin formulas, you can wash your hair, exercise, and style it immediately after leaving the salon.
At The Parlour SG in Kovan, the Cezanne Keratin Smoothing Treatment is priced from $300 to $650 depending on hair length and density. It is one of the treatments we perform most frequently and consistently one of the most requested services by clients dealing with Singapore humidity. |
Does Cezanne Actually Straighten Hair?
This is one of the most common questions and the honest answer is: not in the way most people mean when they say 'straightening.'
Cezanne softens and elongates natural curl and wave patterns. It significantly reduces frizz and volume caused by humidity. But it does not chemically break down or restructure your hair's bonds the way rebonding or Japanese straightening does. If you have a tight curl pattern, Cezanne will loosen and soften it, but your hair will still have movement and texture. If you have wavy hair, it will likely appear noticeably straighter and smoother. If your hair is already relatively straight but prone to frizz, the effect is dramatic.
If you want pin-straight hair that stays straight permanently regardless of humidity, Cezanne is not the right treatment. If you want healthier, more manageable, frizz-resistant hair that still moves naturally and can still be curled or styled, Cezanne is exactly what it promises to be.

How Long Does a Cezanne Treatment Last?
The Cezanne Classic treatment lasts up to five months on most hair types. In practice, results typically begin to gradually fade between the third and fifth month depending on three factors:
Wash frequency — clients who shampoo once a week consistently report results lasting closer to five to six months. Daily washing shortens this to three to four months.
Shampoo type — sulphate-free shampoo extends the treatment significantly. Sulphate-based formulas strip the treatment faster.
Hair type and density — fine hair tends to hold the treatment longer than very thick or coarse hair.
When the treatment fades, it does so gradually, hair does not snap back to its previous state overnight. It softens out rather than reverting suddenly, which makes maintenance timing easy to manage.
For clients who want a lighter, quicker option, Cezanne Express is available, lasting four to six weeks, ideal for a refresh between colour services or as an introduction to the treatment. |
Is Cezanne Treatment Worth It in Singapore?
For most clients dealing with Singapore's climate, yes, with one condition: your expectations need to match what the treatment actually delivers.
If you are spending 30 to 45 minutes every morning blowdrying and straightening your hair to fight frizz, the Cezanne treatment removes that entirely. It reduces blowdry and styling time by up to 30 percent, and for many clients the difference is far more dramatic than that, especially in the first two months after treatment.
For colour-treated hair, the benefit compounds: Cezanne is safe to use on highlighted, balayaged, or bleached hair, and the bond-restoring formula actually improves the condition of chemically processed hair rather than stressing it further. You can also have Cezanne applied on the same day as a colour service.
The people for whom Cezanne consistently delivers the most value:
Anyone with naturally frizzy or humidity-sensitive hair
Clients with curly or wavy hair who want it more manageable without losing all their texture
Colour-treated or bleached hair that needs both smoothing and repair
Anyone who spends significant time daily fighting their hair into submission
The people for whom it may not be the right fit: those who want zero curl or wave permanently, or those with very fine, already-straight hair who do not struggle with frizz, for them, the difference may be subtle.
Finding a Salon in Singapore That Offers Cezanne Smoothing
Cezanne is a professional-grade treatment that requires a trained stylist, not every salon in Singapore stocks or offers it. The Parlour SG in Kovan is one of a small number of salons in Singapore offering the full Cezanne treatment range, performed by stylists with direct training in the application process.
When looking for a salon offering Cezanne or any advanced smoothing treatment in Singapore, ask three questions before booking:
Is the treatment genuinely formaldehyde-free, or does it contain formaldehyde-releasing compounds under another name?
Does the stylist do a hair assessment before recommending the treatment, or is it offered to everyone regardless of hair type?
What aftercare products are recommended, and does the salon stock sulphate-free shampoo for post-treatment maintenance?
The Parlour SG is located in Kovan, five minutes from Kovan MRT. To book a Cezanne consultation or view our full treatment menu, visit our services page or book directly online.
Frequently Asked Questions
What is a semi-permanent hair straightening treatment?
A semi-permanent hair straightening or smoothing treatment is a salon service that reduces frizz and makes hair more manageable without permanently altering its structure.
Unlike chemical rebonding, which uses strong alkalis to break and rebuild your hair's bonds into a straight pattern, semi-permanent treatments infuse the hair with proteins and smoothing agents that seal the cuticle and improve texture. Results typically last three to five months before gradually fading.
The Cezanne Keratin Smoothing Treatment is one of the most widely used semi-permanent smoothing treatments available in Singapore, and is formaldehyde-free.
Are there salons in Singapore offering Cezanne smoothing treatments?
Yes. Cezanne smoothing treatments are available at select professional hair salons in Singapore. The Parlour SG in Kovan is one of the salons in Singapore that offers the full Cezanne Classic treatment, performed by trained stylists.
The treatment is priced from $300 to $650 depending on hair length and density, and can be booked online through Fresha or by calling the salon directly. The Parlour is located five minutes from Kovan MRT.
Does Cezanne straighten hair?
Cezanne smooths and softens hair rather than straightening it chemically. It will loosen and elongate curl and wave patterns, significantly reduce frizz, and make hair more resistant to humidity, but it does not break down your hair's natural bonds the way rebonding or Japanese straightening does. If you have wavy hair, the result can appear quite straight.
If you have a tight curl pattern, expect significant softening and frizz reduction while maintaining some natural texture. For completely straight, permanent results, chemical straightening or rebonding is the appropriate treatment, though it carries higher risk of hair damage over time.
Is the Cezanne treatment worth it?
For most clients in Singapore dealing with daily humidity and frizz, the Cezanne treatment is worth the investment. It reduces styling time by up to 30 percent, keeps hair smooth and frizz-free for three to five months, and actually improves the condition of damaged or colour-treated hair rather than stressing it further. The treatment is formaldehyde-free, requires no downtime, and is safe for all hair types including highlighted and bleached hair.
Whether it is worth it for you specifically depends on how much time and effort you currently spend managing frizz, for clients doing significant daily styling to fight Singapore's humidity, the return on the cost is typically very clear.
How long does a Cezanne treatment last?
The Cezanne Classic treatment lasts up to five months on most hair types. In practice, three to five months is the typical range depending on wash frequency and shampoo choice. Washing hair once a week and using sulphate-free shampoo will maximise the treatment's lifespan. Daily washing with a sulphate-based formula will shorten results closer to the three-month mark.
The Cezanne Express treatment lasts approximately four to six weeks and is suitable for clients wanting a refresh between colour services or a lower-commitment introduction to the treatment.
