How long do smoothing treatments last?

All of our smoothing treatments — including Brazilian Blowout, Cezanne, and Keratin Revolution — last up to 12 weeks with proper care. The QiQi Curly Treatment is different: it's permanent until cut out, since it reshapes the internal bonds of the hair rather than coating or sealing them.

When should I color my hair in relation to a smoothing treatment?

Single-process color can be done before any smoothing treatment, or two weeks after for Brazilian Blowout, Cezanne, or Keratin Revolution. With QiQi, you can color, swim, and style before or after your treatment — there are no restrictions, except one: if you're lightening with bleach, that must be done before the treatment. Toners can be applied anytime afterward to refine brightness or tone if your color shifts slightly. We'll help you plan your color and smoothing schedule so everything stays even, glossy, and healthy.

Will a smoothing treatment change my hair color?

Most smoothing systems can slightly lighten single-process color and may warm or yellow gray and white hair, especially with heat. The QiQi Curly Treatment is the exception — it does not cause color shift and is ideal for clients with lighter tones or gray hair who want smoothness without fading.

Will smoothing make my hair flat or take away volume?

Not unless you want it to. Every service is customized to your texture and preferences — from soft, frizz-free curls to smooth, max results. Our goal is always healthy movement, not heavy or lifeless hair.

Can I swim? Do sulfates, salt water, or chlorine affect smoothing results?

Yes — sulfates, salt water, and chlorine all speed up the fading process. They strip the protective layer that keeps hair smooth and shiny, shortening the life of your treatment. QiQi – Keep All the CURL is our only treatment that allows you to swim immediately after receiving it.

What if my hair is damaged?

If your hair is compromised or overprocessed, we'll still take great care of it — we'll just approach things a little differently. Delicate or fragile areas will be treated with lower heat and a gentler technique, which means your first result may be less dramatic than usual. The goal is to protect your hair's integrity first, then build it back up over time. We can create a restoration plan that combines targeted treatments, proper at-home care, and gradual smoothing so your hair gets healthier with every visit. Once your strands are stronger, we'll be able to perform the treatment at full strength for a more transformative and lasting result.

Can I do a smoothing treatment if I use henna or minoxidil?

No — smoothing treatments cannot be done over henna or on hair being treated with minoxidil. These ingredients can react unpredictably with smoothing systems. We'll help you plan a safe timeline if you've used either recently.

Are these straightening treatments?

No — none of these are straightening treatments. They're smoothing systems, which means they reduce frizz, add shine, and improve manageability while keeping natural movement. Because these treatments don't break and reform bonds like relaxers, we can't guarantee completely straight hair for every texture — but we can guarantee smoother, healthier, humidity-resistant hair that behaves beautifully in Boston's weather. If your hair is frizzy-straight or has a loose wave, it will appear smoother and straighter. If your hair is curly or coily, you'll still have curl and bounce — just softer, shinier, and easier to style. All of our treatments have a cumulative effect and will build on the hair with regular treatments.

What's the difference between the treatments you offer?

Each treatment uses its own science and active ingredients: Brazilian Blowout coats the hair for high-gloss, frizz-free smoothness. Cezanne gently rebuilds and refines the cuticle with a formaldehyde-free formula. Keratin Revolution combines keratin and glycolic acid for stronger smoothing and shine. Results are a little stronger than Cezanne. Formaldehyde-free. QiQi Keep All the CURL permanently reshapes curls for softer, defined texture without losing bounce. Formaldehyde-free. During your phone consultation, we'll help you choose the perfect system based on your hair and goals.

Why choose Brazilian Blowout Boston?

Every stylist is trained in product science, safety, and precise application to deliver consistent, glossy, frizz-free results. Clients travel from NY, RI, NJ, CA, CT, VT, MN, LV, Cape Cod, Quincy, Milton, South End, and beyond because they know they'll leave with hair that's glossier, healthier, and easier to manage — every single time.

Brazilian Blowout vs. Straightening: What's the Real Difference?

September 16, 2026

Straightening treatments reshape hair with permanent chemical bonds. Every client gets the same flat result. A Brazilian Blowout works differently. It cuts frizz and shortens blow-dry time, but how much curl survives depends on how we customize the treatment to your hair.

That difference gets lost all the time. It's worth clearing up before you book anything, because the two services are not the same tool for the same job.

What's the Real Difference Between Smoothing and Straightening?

A Brazilian Blowout is not a straightening treatment. It's an amino acid smoothing formula that coats the hair shaft, calms frizz, and cuts styling time. A true straightening service breaks and reshapes the hair's internal bonds for good. How much curl you keep after a Brazilian Blowout depends on your hair and how we customize the formula. Straightening leaves you no choice at all.

Here's how the three main options compare on the points that matter most:

Treatment	What It Does to Hair Structure	How Much Curl Survives	How It Wears Off
Brazilian Blowout	Coats the hair shaft with an amino acid smoothing layer	Depends on customization. Waves can stay, curl can soften	Fades over 10 to 12 weeks as the coating wears down
Relaxer	Breaks internal bonds to permanently reshape the hair	Little to none. The change lasts until regrowth	Doesn't wear off. New growth is the only curl left
Japanese Straightening	Breaks and reforms bonds with heat, similar to a relaxer	None in the treated section	Permanent on treated hair, grows out slowly over time

Think of it this way. A straightening service has one job. It leaves one result. Smoothing has a range. Some clients leave our studio with waves that dry fast and lose the frizz. Others leave close to straight, because that's what their hair could handle without damage. Both are correct. Neither means the treatment failed.

The formula matters too. A true Brazilian Blowout is an amino acid smoothing treatment. It is not a relaxer. It does not break your hair's internal bonds. It sits on the hair shaft, fills rough cuticle, and calms the frizz that grabs humidity. It does not rebuild your curl from the inside.

Why Clients Confuse the Two

Part of the mix-up is branding. "Keratin treatment" is an umbrella term. Hundreds of different smoothing formulas get sold under that name. They don't use the same chemistry. They don't behave the same way. Brazilian Blowout is one specific brand with one specific formula. Lump them together, and a client ends up expecting one outcome and getting a different one.

We hear from people every week who tried a smoothing service somewhere else. They wanted their waves left mostly alone. They walked out bone straight instead. Now they assume every smoothing treatment does that. It doesn't. Curl pattern, hair density, and how coarse each strand is all change how a formula behaves, and a formula built for one texture can overprocess a different one entirely.

For the full breakdown of how Brazilian Blowout compares to keratin, Japanese straightening, and silk press, read our full comparison guide. Short version: these treatments are not interchangeable. A salon that treats them like they are is guessing with your hair.

What Happens During Your Appointment

A Brazilian Blowout appointment runs 90 minutes to 5 hours, depending on your hair's length and density. Here's what that time looks like, step by step.

Phone consultation first. Every new client gets a free 10 to 15 minute phone call before booking. We ask about your texture, curl pattern, chemical history, and what you want the treatment to do. Done right, this call rules out the wrong result before you sit down.
Clarify the hair. Clean, dry hair without heavy product is ideal, though not required. We clarify regardless, so old product residue doesn't block the formula from absorbing.
Section the hair. We divide your hair into sections based on thickness and length. This keeps the application even from root to end.
Apply the customized formula. The formula goes on section by section, adjusted for what your hair needs. Highlighted, fine, or delicate areas get a lower temperature and a lighter hand, so we don't overprocess hair that's already been through color.
Process and seal with heat. Heat tools seal the formula into the hair shaft. This step is where the frizz reduction happens, and it's why real ventilation matters, not just a fan in the corner.
Rinse. Unlike some smoothing services that make you wait days before washing, you can wash the same day. No three day waiting period here.
Style and check the result. We blow-dry and check how the hair moves before you leave, then write notes for your next visit.

Done right, you walk out with hair that dries faster and holds less frizz in humidity. It still looks like your hair. Not someone else's.

Who Should Book This, and Who Should Look Elsewhere

This treatment works well for clients tired of fighting frizz every morning. It works for clients who want less blow-dry time and are open to a range of outcomes, not just pin-straight hair. It also works for clients who want to keep their waves but lose the puff. That's one of the most requested outcomes we hear.

It suits thick, coarse, and very curly hair just as well as fine hair, since the level we choose changes to match what your hair can safely handle. That's the entire point of the phone consultation before anything gets applied.

It is not the right fit for anyone who is pregnant or breastfeeding. We do not perform the Original Brazilian Blowout on those clients. We do offer formaldehyde-free options. We tell every client upfront that those alternatives do not necessarily give the same result as the original formula. Setting that expectation honestly matters more to us than booking the appointment.

It's also worth saying plainly: if you want permanently straight hair with zero wave ever again, a smoothing treatment isn't built for that. That's a different service, a different chemistry, and a different conversation entirely.

How We Customize Results: Classic, Lighter, Heavier

We offer three result levels. The right one depends on your texture, your curl's strength, and what you're trying to solve.

Level	What It Does	Who It Suits	Upkeep
Classic	Standard frizz reduction, keeps most of your natural texture	Clients with mild to moderate frizz who want their wave pattern intact	Holds 10 to 12 weeks with normal washing
Lighter	A gentler pass built for fine, damaged, or heavily highlighted hair	Clients with delicate hair who still want smoothing benefits	A softer smoothing effect, since we protect compromised hair over speed
Heavier	A stronger reduction in curl and frizz for a noticeably smoother finish	Clients with thick, coarse, or very curly hair chasing more smoothness	Same 10 to 12 week window, often fading a bit slower

The first appointment is a starting point. It's not locked in forever. We keep notes on what we used and how your hair responded. Then we adjust at your next visit based on what you liked and what you didn't. That's the whole point of customization. It gets more accurate over time, not less.

What Clients Get Wrong About Brazilian Blowout

The biggest fear is that the treatment will strip out curl completely and leave hair flat and lifeless, the way a bad straightening job can. We hear this constantly, usually from people who had a rough experience somewhere else. Sometimes it was a salon with poor ventilation, where the whole appointment felt uncomfortable and out of their control.

That fear is fair. It's also fixable with the right consultation and the right studio. After more than 10,000 smoothing treatments in this studio since 2016, the worry we hear most at that first phone call is some version of "will this take away what I like about my hair." Our answer comes from the work itself. Client retention here has stayed above 80 percent for years, and that only happens when results match what people actually wanted, appointment after appointment.

Our space is a private, fully ventilated studio at Marina Bay in Quincy, built around this one service. There's no guessing about what the room smells like or how long you'll breathe in fumes. Ventilation was designed into the space from the start, not bolted on later.

Another common mistake: assuming color and smoothing don't mix, or that they need months apart. Highlights usually go before a Brazilian Blowout. Single-process color usually needs 10 to 14 days after, since the smoothing formula can lighten fresh color. That's a scheduling detail, not a reason to skip either service. If protecting color-treated hair through a smoothing treatment worries you, here's how custom smoothing protects color and strength.

A third mistake worth naming: booking a smoothing treatment right before or after another chemical service without telling anyone. If your colorist doesn't know a Brazilian Blowout is scheduled too, timing can go wrong fast. Always mention every upcoming service at your consultation, not just the one you're calling about.

How Long Results Really Hold

Results last 10 to 12 weeks for most clients, not 12 days. That window shifts a little depending on your texture, how often you wash, and what Quincy's coastal air does to your hair between visits. If you've dealt with coastal frizz from humidity and salt air before, you already know how fast frizz creeps back without a maintenance plan. Here's what we tell clients about beating that coastal frizz.

During the holding window, wash and style as normal. There's no waiting period after your appointment and no special shampoo requirement beyond avoiding anything that strips hair unnecessarily. Near the end of the window, frizz gradually returns, especially in humid stretches. That's normal fade. It's not a sign the treatment failed. You can see how real results grow out on our Instagram, which tells you more than any same-day before-and-after photo.

If you're managing curl at home between appointments and want to stretch the smooth days further, our guide to air-drying curly hair without humidity frizz covers the shower habits that help the most.

When you're ready to book, the same phone consultation process applies. We'll talk through your hair, your history, and what you want before anything gets scheduled.

Frequently Asked Questions

Will a Brazilian Blowout make my hair completely straight? Not necessarily. The result depends on how we customize the treatment, your natural texture, and which level you choose. Many clients keep their wave pattern and simply lose the frizz.

What are the potential downsides of a Brazilian Blowout? Like any chemical service, it needs to be customized correctly for your hair's condition, especially on fine, damaged, or heavily highlighted sections. Without that customization, results feel less predictable, which is why the consultation happens before the formula ever touches your hair.

How long do most Brazilian Blowouts last? Most clients see results hold for 10 to 12 weeks, depending on hair type, washing habits, and daily exposure to humidity.

Does hair go back to normal after a Brazilian Blowout? Yes. As the smoothing formula fades, your natural texture and curl pattern return. It's not a permanent change to the hair's structure.

Do they wash your hair before a Brazilian Blowout? We clarify the hair before the treatment no matter how you arrive, clean or product-heavy, so buildup doesn't block the formula from absorbing.

Is Brazilian Blowout still a thing? Yes. It's still the treatment we book most often in this studio, because it can be customized instead of forcing one flat result on every client.

Which is better, keratin treatment or Brazilian Blowout? "Keratin treatment" covers hundreds of different formulas with different chemistry and different results. Brazilian Blowout is one specific, amino acid-based formula we customize per client, which is a real difference when you're deciding what to book.

Can I get a Brazilian Blowout if I'm pregnant or breastfeeding? We do not perform the Original Brazilian Blowout on clients who are pregnant or breastfeeding. We do offer formaldehyde-free alternatives, though those may not give the same result as the original formula.
