From the Specialists at Parlay Hair and Beauty, Jensen Beach, Florida
It is the question we hear most from the chair, usually from a client holding up a section of hair that looked smooth at home and did not survive the walk across the parking lot: should I get a Brazilian Blowout or a keratin treatment?
The Brazilian Blowout vs. keratin treatment decision does not have one right answer. Both are professional smoothing services, both are sealed in with heat, and both make Treasure Coast humidity far less of a daily fight. But they behave differently after the appointment, last different lengths of time, and suit different hair types and lifestyles. Here is how to choose.
The Short Answer
Choose the Brazilian Blowout if you cannot give up two or three days of normal life after the appointment, you swim or work out often, you want to keep some natural wave or curl, your hair is fine, or you want color and smoothing on the same day.
Choose a keratin treatment if your hair is thick, coarse, or very frizz-prone, you want the straightest result a non-permanent service can give, you can plan around a short no-wash window, and you would rather book less often.
Book a consultation first if you are somewhere in between, your hair has a complicated color history, or you are pregnant or planning to be. Parlay’s free hair consultation is how most of our smoothing clients make this exact decision.
Why “Keratin Treatment” Means Different Things at Different Salons
Brazilian Blowout is a brand – one specific smoothing system with its own formulas and stylist certification. “Keratin treatment” is a category used for dozens of products, so one salon’s keratin treatment may have little in common with another’s. That is why a friend’s keratin “only lasted a month” tells you very little.
At Parlay the comparison is specific: our Keratin Complex treatments on one side and our certified Brazilian Blowout service on the other. For goals that fall between the two, we also offer gentle, medium, and intensive smoothing treatments.
How Each One Works
Frizz is a cuticle problem. When the outer layer of the strand is raised – from natural texture, color, sun, or salt – hair pulls moisture from humid air, swells, and frizzes. Both treatments smooth and seal that cuticle, then lock the result in with a flat iron at high heat. That heat-sealing step is the most skilled part of either appointment.
The difference is depth. The Brazilian Blowout builds a smoothing layer around the outside of the strand, so it is finished the moment you leave and keeps more natural movement. Keratin Complex works more deeply on the bonds that control texture, so it reaches a straighter result and generally lasts longer.

The Waiting Window Is Usually the Deciding Factor
On paper, “no washing for up to three days” sounds easy. On the Treasure Coast it means no sweaty morning walk, no getting caught in a 3 p.m. downpour, no ponytail for the gym, and no clipping your hair up for a boat day out of Sandsprit Park. A crease or a soaking during that window can set into the result.
That is not a reason to skip keratin – it is a reason to schedule it well. Clients who love Keratin Complex book it before a quiet stretch at home. Clients who love the Brazilian Blowout are usually the ones who do not have a quiet stretch to give. If you swim off Jensen Beach Public Beach, do laps in Palm City, or commute from Port St. Lucie to Stuart with kids and workouts in between, the no-wait Brazilian Blowout tends to fit your life better.
Which One Suits Your Hair
Fine or thin hair: The Brazilian Blowout or a gentle smoothing treatment is the safer start. It removes frizz without flattening the body fine hair needs.
Thick, coarse, or very frizzy hair: This is where keratin earns its place. Dense hair that frizzes the moment you step outside usually needs the stronger result to last through a Florida summer.
Curly hair you want to keep: The Brazilian Blowout can be applied to keep your curl pattern while removing the frizz around it. Tell us at the consultation if keeping your curl is the goal.
Color-treated or blonde hair: Both can work, and the sealed cuticle helps color hold its shine. Lightened hair is more porous, so we check it first and adjust the formula. The Brazilian Blowout can follow color on the same day; keratin is generally done once color work is complete. Our guide on how to care for hair after a color appointment covers the at-home side.
Damaged hair: If your hair is breaking or recovering from heavy lightening, a few weeks of strengthening treatments may need to come first. We would rather tell you to wait than seal damage in.
A Straight Answer on Formaldehyde
Many smoothing solutions across many brands have used formaldehyde or ingredients that release it when heated, and that chemistry is part of why these treatments last. It is also why the industry has been under regulatory scrutiny for years. Our advice is simple: ask which formula will be used on your hair, since many brands now offer formaldehyde-free options that may trade some longevity for the difference. Mention asthma, a sensitive scalp, or past reactions at your consultation. If you are pregnant or breastfeeding, talk to your doctor before any chemical smoothing service – we are happy to share the formula’s ingredients so you can review them together.
Aftercare That Makes It Last
Brazilian Blowout: No waiting period. Wash, tie your hair up, or swim whenever you like.
Keratin: Keep hair down, dry, and straight for the waiting period your specialist gives you – no ponytails, clips, or tucking behind the ears, and stay out of rain and steam.
For both:
- Sulfate-free shampoo at every wash – this is not optional.
- Wash every two to three days, with dry shampoo in between.
- Rinse with cool or lukewarm water.
- Use a UV-protecting leave-in before heading outside.
- Before the ocean or pool, wet your hair with fresh water and apply a protective oil, then rinse thoroughly afterward.
Humidity, salt air, and sun wear any treatment down faster here, so Parlay recommends refreshing a Brazilian Blowout every eight to ten weeks in Jensen Beach, and booking keratin maintenance at the first sign of frizz returning. Summer storms are especially hard on a fading treatment – our post on rainy season hair care mistakes to avoid has more on getting through it. Planning for a wedding or big event? Book smoothing about ten days to two weeks before, so the result has settled by the day.
The Bottom Line on Brazilian Blowout vs. Keratin Treatment
There is no universal winner in the Brazilian Blowout vs. keratin treatment debate – only the better fit for your hair and your week. For active Treasure Coast women who swim, sweat, and cannot spare three days, the Brazilian Blowout is easier to live with. For thick, coarse hair that needs maximum smoothing, and for clients who can plan around a short waiting window, keratin often gives the longer, straighter result.

Frequently Asked Questions
Which is better for frizz in Florida humidity? Both work well. Keratin gives a straighter result and suits thick, coarse hair. The Brazilian Blowout removes frizz while keeping movement, with no downtime.
How long does each last on the Treasure Coast? The Brazilian Blowout lasts about ten to twelve weeks, and we recommend refreshing every eight to ten weeks here. Keratin Complex lasts about twelve to sixteen weeks, usually twelve to fourteen for Jensen Beach clients.
Can I swim after my treatment? After a Brazilian Blowout, right away. After keratin, wait until the waiting period has passed and you have done your first wash.
Can I switch from one to the other? Yes. Your specialist will check how much of the previous treatment remains and plan the timing so the two work together.
