Vegan Glyoxylic Acid
A vegan, formaldehyde-free ingredient that enhances manageability without damage, creating new cross-links within the hair shaft for long-lasting smoothness.
Hydrolyzed Keratin

WHY CHOOSE CEZANNE?

Strengthens Hair
The low pH technology restores bonds broken by thermal, mechanical, or high pH services, reinforcing hair structure and health

Safe for Color-Treated Hair (Including Blondes!)
Unlike some smoothing treatments, Cezanne won't strip or alter hair colour and is gentle on blonde hair, preventing brassiness or unwanted tonal changes.

CLASSIC vs EXPRESS

Classic Smoothing Treatment — starting at $400
Express Smoothing Treatment — starting at $250
Final pricing and service time may vary depending on hair length, thickness, and natural texture of the hair.

POST-TREATMENT

There is no waiting period

The treatment can be done on the same day as your colour service.

This means you can work out, swim, wash your hair, use hair pins, tuck your hair behind your ears, and wear hair ties immediately after the treatment.

To maintain results, we recommend using a sulfate-free shampoo to keep hair smooth and frizz-free for longer.

Most clients notice their hair feels ‘done’ even on days they do less.

Not sure which treatment is right for you? We’re happy to guide you.

All treatments will reduce frizz and deliver smoother and more manageable hair.

The main difference is how the product is applied and the longevity of the treatments.

The Classic treatment can last up to 5 months and
The Express treatment can last up to 8 weeks.

THE PROCESS

    1. Shampooing
      Your hair is washed twice with a clarifying shampoo to remove any product buildup, oils, and impurities, ensuring the treatment can penetrate effectively.

    2. Rough Blowdry
      After shampooing, your hair is dried quickly without focusing on perfect smoothness.

    3. Application of the Classic Smoothing Treatment
      The Cezanne smoothing treatment is applied evenly throughout your hair and left on to process for 30 minutes.

    4. Rinsing
      The excess treatment product is rinsed out of your hair.

    5. Heat Protectant and Blow Dry
      A heat protectant spray is applied to shield your hair from heat damage, followed by the blow dry to smooth it out.

    6. Flat Ironing
      Your hair is flat ironed to lock in the treatment, sealing the cuticle for a smooth, shiny, and healthy finish.

    1. Shampooing
      Your hair is washed twice with a clarifying shampoo to remove any product buildup, oils, and impurities, ensuring the treatment can penetrate effectively.

    2. Application of the Express Smoothing Treatment
      The Cezanne Express Treatment is applied evenly throughout your hair wet and left on to process for 15 minutes.

    3. Rinsing

THE RESULTS?

In both cases, the treatment doesn’t break or permanently change your hair’s structure.

Instead, it creates a lightweight, flexible layer around each strand that:
• Smooths the cuticle
• Reduces frizz and puffiness
• Enhances shine
• Makes styling easier

Over time, this layer gradually fades, allowing your hair to return to its natural state.

HOW DOES A CEZANNE TREATMENT WORK?

Cezanne works by smoothing and sealing the outer layer of the hair (the cuticle) to reduce frizz, enhance shine, and improve manageability.

To visualize it, think ig your hair like an elastic band.

Classic Smoothing Treatment
With the Classic treatment, the hair is blow-dried smoothing and stretched—like a taut elastic band.

The Cezanne formula is then applied, processed, rinsed and sealed into the hair using heat.
As it processes, it forms a flexible coating around the hair locking in that smoother, more controlled shape.

This is what gives you the most frizz reduction and the smoothest overall result, while still maintaining natural movement.

Express Smoothing Treatment
With the Express option, the hair is not stretched as tightly—more like a relaxed elastic band.

The treatment is still applied and sealed, but because the hair’s natural pattern isn’t pulled straight during the process, more of your natural wave or curl is preserved.

The result is softer frizz control with a more natural, lived-in texture.

CLASSIC vs EXPRESS TREATMENT

Which treatment should I book?

We’ll help guide you, but there’s a quick way to understand the difference.

Both treatments smooth and reduce frizz.
The difference is how much smoothing you want and how long you want it to last.

The Classic treatment can last up to 5 months and
The Express treatment can last up to 8 weeks.

CHOOSE THE CLASSIC TREATMENT IF:

  • Ideal for those with previous keratin smoothing treatments

  • You want maximum frizz reduction

  • Prefer a smoother, more polished finished

  • Prefers to wear their hair straight most of the time.

  • You want maximum frizz reduction

  • You want a better control of your hair if it’s puffy, bulky and often find your hair hard to manage.

Results: Smother, more controlled hair with minimal daily effort.

CHOOSE THE EXPRESS TREATMENT IF:

  • Perfect for first-timers or those hesitant to commit to the longer treatment

  • Great if you prefer wearing your hair wavy or curly most of the time

  • Want to keep your natural wave or curl

  • You prefer a more lived-in finish

  • You want the frizz control without flattening your curl texture

  • You just want your hair to be easier to manage

  • You want it for just a season or a short trip with a humid climate

Results: Softer, more defined nature texture with reduced frizz.

Frequently Asked Questions

Before you book… These are the questions that are most frequently asked in our chairs.

SAFETY & DAMAGE

  • No.

    When performed professionally, Cezanne is not considered a damaging service. It does not break or permanently alter the internal bonds of the hair. Instead, it works on the cuticle to smooth and seal.

    The formula also contains a plant-based protein that helps support the hair’s strength and overall feel.

    That said, regular trims are still essential for maintaining healthy hair.

  • It depends on the condition of your hair.

    Cezanne does not break or permanently alter the internal structure of the hair, and many clients find their hair feels smoother and more manageable after.

    However, if the hair is significantly compromised (for example, overly processed or fragile), we may recommend focusing on restoring the hair first before performing a smoothing treatment.

    What’s the best approach?
    We’ll assess your hair during your consultation and recommend the best plan based on its current condition.
    In some cases, we may adjust the service (or suggest waiting) to ensure the healthiest, most even result.

    Maintaining the integrity of your hair always comes first. If your hair isn’t ready, we’ll tell you—your hair health always comes first.

    The key thing to understand
    Smoother hair doesn’t always mean healthier hair.

  • No.

    Cezanne is formaldehyde-free and does not release harsh chemical fumes.

    You may see a light steam during the straightening part of the service—this is simply the product being sealed into the hair, not fumes.

    This makes it a much cleaner, more modern alternative to traditional smoothing treatments.

  • The product is applied close to the root, but not directly onto the scalp.

    Because it is a liquid formula, a small amount may come into contact with the scalp.

    Some clients may experience mild sensitivity (such as slight itching), which typically resolves once the treatment is rinsed.

  • Most clients are completely comfortable during the service.

    Some may experience mild sensitivity, such as slight itching or warmth while the treatment is processing. This is temporary and typically resolves once the treatment is rinsed out.

  • The flat iron finished after the treatment is rinsed and blow-dried is controlled and typically lower than what most people use at home.

    • In-salon for the treatment: ~340°F–380°F

    • At home: often 400°F–450°F

    The hair is passed through the flat iron several times (five passes), but each pass is quick and controlled, not slow or excessive.
    The temperature of the flat iron is determined based on natural hair texture.

    For most clients, this is actually less heat exposure than their regular styling routine.

  • The hair is passed through the flat iron several times to evenly seal the treatment into the hair.

    Each pass is quick—not slow or prolonged—so the heat exposure remains controlled and consistent.

    The key difference
    At home, heat styling is often:
    • Higher temperature
    • Repeated daily

    In the salon, the heat is:
    • Lower and customized
    • Applied professionally
    • Done once, in a controlled service

    What this means for your hair
    For most clients, this is actually less heat exposure than their regular styling routine.

    The temperature is also adjusted based on your hair type—finer hair uses lower heat, while coarser hair may require slightly higher heat for proper sealing.

  • The treatment is designed to be a comfortable in-salon experience.

    We also prepare the hair with a heat protectant before blow-drying to support the hair during the process.

    This is a much cleaner, more modern alternative to older smoothing treatments.

    Cezanne is formaldehyde-free, so there are no harsh chemical fumes. Any steam you see is just the product being sealed into the hair during heat styling of the service.

HOW IT WORKS

  • A professional smoothing treatment designed to reduce frizz, enhance shine, and make your hair significantly easier to manage—without permanently straightening it.

    Think: Your natural texture, just smoother, softer, and more controlled.

  • Cezanne works by smoothing and sealing the outer layer of the hair (cuticle), not changing the internal structure.

    Think of your hair like an elastic band:
    We’re not changing what’s inside—we’re smoothing and sealing the outside so it behaves better.

    This creates a lightweight, flexible layer that:
    • Reduces frizz and puffiness
    • Enhances shine
    • Improves manageability

    Over time, this layer gradually fades, allowing your hair to return to its natural state.

  • Cezanne has been around in the professional hair industry for over a decade.

    It was introduced in the early 2010s as one of the first formaldehyde-free smoothing treatments designed to offer a safer, more modern alternative to traditional keratin services.

    Since then, it has become a trusted salon service worldwide, continuously evolving with updated formulas and technology while maintaining its focus on healthy, smooth, and manageable hair.

WILL THIS WORK ON MY HAIR TYPE?

  • Yes—Cezanne works very well on straight hair that tends to get frizzy.

    The treatment smooths the cuticle to reduce frizz and flyaway, without changing your natural texture.

    The key difference
    Your hair won’t become “straighter”—it will just look mored refined, glossy, and controlled.

  • Yes—Cezanne can be a great option for fine hair, this treatment is not just limited for thick or coarse hair.

    Because it works on the outer layer of the hair, it smooths frizz without permanently changing your natural texture.

  • Cezanne smooths the outer layer of the hair to reduce frizz and enhance shine, but it does not add oil or residue to the hair.

  • • Softer and silkier
    • Less frizzy and easier to manage
    • More controlled in humidity
    • Still able to hold volume and style

  • Cezanne does not remove your curl pattern, but it will relax and soften it.

    Your curls will appear smoother, more defined, and less frizzy—especially in humidity.

    What can I expect?
    • Reduced frizz and puffiness
    • Softer, more manageable curls
    • More definition with less effort
    • Easier styling and detangling

    The key thing to understand:
    Your curl pattern will still be there—but it may feel slightly looser and more elongated depending on the level of smoothing (Classic vs Express).

    We customize between the Classic and Express smoothing options based on how much of your natural curl you want to keep.

  • This is what we at NOOK salon have noticed:

    Loose waves (2A–2C)
    • Waves appear smoother and more polished
    • Less frizz and puffiness
    • More definition with less effort
    • Easier air-drying with a more “intentional” finish
    Result: soft, controlled waves that look styled—even when they’re not.

    Curly hair (3A–3C)
    • Curls become softer and more elongated
    • Reduced frizz and bulk
    • Easier detangling and styling
    • More definition with less effort
    Result: smoother, more manageable curls with a softer overall shape.

    The key thing to understand:
    Your texture will still be there—but it may feel slightly looser depending on the level of smoothing.

  • This is what we at NOOK salon have noticed:

    Cezanne can be done on coily hair, but it will soften natural pattern.

    Because tighter textures have more structure, the result will be a looser, more elongated curl pattern.

    What can I expect?
    • Noticeably reduced shrinkage
    • Softer, more elongated coils
    • Easier detangling and styling
    • Less frizz and more manageability

    The key thing to understand
    This is not a curl-preserving service for tighter textures.
    Your natural pattern will still be present, but it map appear looser and less compact.

    Who is this best for?
    • Clients who want easier manageability
    • Those who regularly stretch, blow dry, or silk press their hair
    • Anyone looking to reduce shrinkage and styling time

    We’ll always consult with you first to make sure the result aligns with how you like to wear your hair.

  • Cezanne is a great option if you:
    • Struggle with frizz or humidity
    • Want smoother, more manageable hair without losing your natural texture
    • Spend time styling your hair and want to reduce your daily routine
    • Prefer a polished, low-maintenance finish

    It may not be the right fit if you’re looking for:
    • Completely straight, flat hair
    • Maximum texture removal

    Not sure? We’ll guide you—so you end up with a result that actually fits your hair and how you like to wear it.

WHAT WILL MY HAIR ACTUALLY LOOK LIKE?

  • • Noticeably less frizz
    • Faster, easier styling
    • Softer, shinier hair
    • Better control in humidity

    Most clients say their hair feels “done” even when they do less.

  • No—and that’s the point.

    Cezanne softens and relaxes your texture rather than flattening it, so you keep your natural movement while losing the frizz.

    Perfect if you want polished hair that still feels like you.

  • Yes—but significantly less.

    Blow dries are faster, frizz is reduced, and your hair holds styles better with less effort.

  • Absolutely.

    Your hair will actually style more smoothly and hold curls better—with less frizz and more shine.

COLOUR & SERVICE COMBOS

  • Yes.

    Cezanne is compatible with colour-treated, highlighted, and lightened hair.

    It’s a great option if you want smoother hair without compromising your colour.

  • This depends on your hair and your colour goals—there is no one-size-fits-all approach.

    • Brunettes / single-process colour: Typically done before to enhance shine and richness.

    • Blondes (foils, bleach, high-lift): Typically done after to maintain brightness and tone.

  • There isn’t a one-size-fits-all approach—different salons may recommend different timing depending on their technique and experience.

    At NOOK salon, we follow a customized approach to ensure the best possible result for both your colour and your smoothing treatment.

    • For brunettes / single-process colour:
      Because the treatment works at a higher pH, we typically recommend refining the colour after the Cezanne service to maintain richness and tone.

    • For blondes (foils, bleach, or high-lift colour):
      Processing time may be slightly longer, and we adjust accordingly to achieve your desired brightness and tone.

  • Yes—and in many cases, it’s recommended.

    Cezanne pairs well with colour services and can be done in the same appointment to enhance shine and smoothness.

    Haircuts can also be done during the same visit to refine the final shape.

CLASSIC VS EXPRESS

  • Think of your hair like an elastic band:

    • Classic (Maximum Smoothing):
    Hair is stretched smooth → more frizz reduction and a sleeker finish

    • Express (Soft Smoothing):
    Hair stays more relaxed → softer frizz control while keeping natural texture

    Same treatment, different finish—customized to how you wear your hair.

  • Classic
    Best if you want:
    • Maximum frizz reduction
    • A smoother, more polished finish
    • Less daily styling
    Result: smooth, controlled, low-maintenance hair.

    Express
    Best if you want:
    • To keep your natural wave or curl
    • A softer, more natural finish
    • Light frizz control
    Result: more defined, manageable natural texture.

    The key thing to know:
    Both treatments improve manageability.
    The difference is how long you want the results to last.

    Not sure which to choose? Book Classic.
    We can adjust your service in-salon.

  • Yes—you can alternate between Classic and Express depending on your needs and lifestyle.

    Many clients choose a stronger smoothing option during more humid months, and a lighter option when they want to keep more natural texture.

    How does that usually look?
    Classic: Ideal for high humidity seasons (like summer) when maximum frizz control is needed.
    Express: Great for lower humidity months or when you want a softer, more natural finish.

    The key thing to know
    The best option depends on your hair type, how you wear your hair, and how much smoothing you prefer at the time.

APPOINTMENT DETAILS

  • Approximately 2-3 hours depending on your hair length, density, and texture.

  • None.

    You can wash your hair, tie it up, and resume your normal routine immediately.

  • At NOOK salon, most guests can book a Cezanne treatment without a separate consultation.
    If your har has a complex colour or chemical history, we may recommend one before your appointment.

LIMITATIONS & CONSIDERATIONS

  • Cezanne is designed to be applied throughout the entire head of hair to ensure a smooth, even, and consistent result.
    Applying the treatment to only one area can lead to uneven texture and inconsistent results between treated and untreated sections.

    The key thing to know
    The service is intended to be seamless from root to ends, rather than spot-treating specific areas.

  • Cezanne is not typically done as a root touch-up service.

    Because the treatment works by smoothing and sealing the entire hair strand, applying it only at the roots would create an uneven result between the new growth and the previously treated hair.

  • Even if your ends still feel smooth, they’ve naturally experienced wear over time.

    Refreshing the full length ensures:
    • Consistent texture from root to ends
    • Even frizz control throughout the hair
    • A seamless, polished finish

    While your ends may still feel smooth, we typically recommend refreshing the full length to keep the result even and consistent.

  • Yes—but extensions must be removed prior to the service.

    The treatment cannot be properly applied or sealed at the points of attachment, and heat cannot safely be used over them.

    Leaving extensions in during the service can lead to uneven results and may compromise both the treatment and the extensions.

    For best results, the treatment is performed on natural hair only.

  • If you’re looking for:
    • Completely straight, flat hair
    • Maximum texture removal

    A different straightening service may be more suitable for your goals.

POST-TREATMENT & HOME CARE

  • For the Classic Treatment: Around 4 months
    For the Express Treatment: Around 8 weeks

    Depending on your hair type and at-home care.

    Using sulphate-free shampoo is recommended.

  • Cezanne gradually fades over time, allowing your hair to return to its natural state.

    As the treatment wears off, you may start to notice more of your natural texture again—including dryness, frizz, or reduced smoothness.

    What this means
    This is completely normal and simply means the treatment is nearing the end of its lifespan.

    What you can do:
    At this stage, you can:
    • Refresh your treatment
    • Focus on hydrating and strengthening your hair with the right products

  • Using sulfate-free products will help extend the life of your treatment.

    We’ll recommend the best options for your hair.

  • This is a question we get a lot.

    For Classic:
    Every 5–6 months: for clients who want smoother hair year-round and is ideal for consistent, long-term smoothing (year-round maintenance).

    For Express:
    Perfect for short-term smoothing, like trips or special occasions or events, vacations, or seasonal humidity.

    Many clients incorporate this into their routine to keep their hair consistently smooth, manageable, and low-maintenance throughout the year.

  • Yes—Cezanne can be done on a recurring basis.

    Most clients return every 5-6 months for Classic treatment, depending on how long they like to maintain their results.

    What about Express?
    Because the Express treatment offers a softer, shorter-term result, it’s often done more flexibly.

    Some clients choose to maintain it more regularly, while others book it around seasons, events, or travel.

  • It’s normal to notice a subtle scent after your treatment.

    This comes from the smoothing ingredients and proteins used during the service, which can be more noticeable when the hair is exposed to heat or moisture (like after washing or styling).

    The scent is temporary and will gradually fade after a few washes.

    If anything smells unusually strong or persists, feel free to reach out—we’re always happy to take a look (or smell in this case).

Ready for easier, more manageable hair?

Whether your hair is straight, wavy, curly, or coily, this treatment is customized to smooth frizz without taking away your natural texture.
If you’re constantly managing frizz or spending time styling your hair, this is the service that changes that.
