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.

Do They Wash Your Hair Before a Brazilian Blowout?

October 7, 2026

Yes. We wash and clarify your hair at the start of every Brazilian Blowout appointment. Not because dirty hair ruins anything, but because the smoothing solution has to reach the strand with nothing sitting on top of it: oil, dry shampoo, styling gel, salt air off the water. Clean here does not mean squeaky. It means clear.

We have run this same prep step through more than 10,000 smoothing treatments in our private, fully ventilated studio on Beach Street in Quincy. That number matters because it means this is not theory. It is what we have watched go right and go wrong at the bowl.

What the Clarifying Wash Actually Changes

The smoothing solution has to sit on the cuticle evenly to set evenly. Product residue coats the cuticle in a thin film. Where that film is heavier, the solution sits higher and sets softer. Where the hair is clear, it sets the way it should. That is how you end up with a head that is smooth through the back and still puffy around the hairline.

So the clarifying step is not about hygiene. It is about making the whole head behave like one surface instead of six different ones.

It also affects your clock. Our appointments run anywhere from 90 minutes to five hours depending on length, density and what your hair needs. A head carrying heavy buildup adds time at the bowl, sometimes 15 or 20 minutes on the front end, because we are not moving forward until the hair is genuinely clear. Plenty of our South Shore clients come in after three days of dry shampoo. We still wash first. It just takes a little longer.

If you want the bigger picture on how this compares to other smoothing options, our piece on which treatment holds up better covers the full comparison. This page is only the wash-day piece of it.

The Prep at the Bowl, Step by Step

Here is the sequence, in order, and what each step looks like when it is done right.

Clarifying pass. We shampoo with a clarifier, not a daily shampoo. Done right, the lather goes flat and slow on the first pass, because it is lifting product off the shaft rather than foaming on top of it.
Check the shaft and the scalp line. We run wet strands between fingers, looking for slip that should not be there and for the gritty feel of salt buildup. Done right, the hair squeaks slightly at the mid-shaft and the roots feel clean, not coated.
Second pass or a softer pass, depending on the hair. Coarse or heavily built-up hair gets a second round. Fine, highlighted or fragile hair gets a lighter, shorter one instead. Done right, the hair is clear without being stripped raw.
Rough dry and section. We take the hair to fully dry, then part it into working sections. Done right, there is no damp spot left anywhere, because damp hair dilutes the solution and gives you an uneven result.

That is the whole prep. It is boring on purpose. Boring prep is what makes the rest of the appointment predictable.

How the Wash Step Changes by Hair Type

Customization does not start once the solution goes on. It starts here.

Coarse hair with a strong curl pattern usually needs the second clarifying pass, because thick strands hold product deeper and one round does not always clear them. Fine hair gets less handling and a shorter clarifier contact time. Highlighted or chemically delicate sections get the most conservative approach we have: less scrubbing, more care around the compromised areas, no aggressive work at the mid-lengths where the hair is already thinner.

All of it goes into your treatment notes. If your hair needed two passes this time, or a lighter touch through your highlights, we have that on record for next time. Nobody starts from scratch on a second visit.

This is also part of what your complimentary phone consultation covers before a first appointment. We ask about your chemical history, your last color, and what your daily product routine looks like, so we know roughly what we are dealing with before you sit down.

When You Can Wash It Again

This is where a lot of people carry over a rule that does not apply.

Brazilian Blowout has no three-day waiting period. You can wash your hair the same day the treatment is finished. No 72 hours of sleeping on your back. No skipping the gym. No pinning your hair up for a long weekend and hoping for the best.

That is one of the real differences between this treatment and some of the older smoothing options people have had before. If you have a workout streak, a swim, a work trip or an event right after your appointment, it does not change your plan. Wash when you need to wash.

What does affect how long your result holds is the shampoo you reach for afterward. Over thousands of treatments, we have seen harsh, stripping formulas wear a result down noticeably faster than a gentler one. We go over specific recommendations at your appointment, based on your hair and how you wash. You can also see what the full 10 to 12 week window looks like on our Brazilian Blowout service page.

What Clients Get Wrong

The first mix-up is that three-day rule. People show up for their next appointment having avoided the pool and the gym for days they did not need to lose. Ask us at the consultation if you are unsure. We would rather answer it once than have you skip a week of workouts for nothing.

The second is over-washing right before the appointment. More washing does not mean a better result. Scrubbing your scalp raw the morning of does nothing for the treatment and can leave your scalp tender for a long sit. One normal wash is plenty. Coming in on day three is also fine.

The third is thinking a home wash can stand in for what we do at the bowl. Your shampoo is built to clean your scalp and rinse out conditioner. It is not built to pull salt residue and layered dry shampoo off the shaft. Different tool, different job.

Frequently Asked Questions

Do I need to wash my hair the morning of my appointment? No. Come as you are. We wash and clarify in the studio as part of the treatment, using a stronger shampoo than what you keep at home. Clean hair walking in is welcome but it does not change our process.

Can I wash my hair the same day the treatment is finished? Yes. Brazilian Blowout does not carry a three-day wait. You can wash, swim, work out or shower the same day without hurting the result.

What if I have a lot of dry shampoo or product buildup? Tell us before we start. It does not change whether we can treat you, but it may mean a second clarifying pass and a little extra time at the bowl before we begin.

Will the clarifying step be different if my hair is highlighted or fragile? Yes. We adjust based on your texture, curl pattern, strength of curl and the condition of the hair, so delicate or highlighted sections get a lighter, shorter pass. It goes in your notes so we repeat the same approach next visit.

Book Your Appointment

The wash is a small part of the appointment, but it is the part that decides whether the rest of it sets evenly, and how we run it depends entirely on your texture, curl pattern, strength of curl and condition. That is what we sort out on the phone before you ever sit down. Book a consultation and we will walk you through what your first visit looks like start to finish.
