Brazilian Blowout
Brazilian Blowout is a branded professional smoothing treatment — liquid keratin with acai — famous for its no-waiting-period result: hair is rinsed, styled and finished the same visit. It smooths and de-frizzes for around three months. The brand made keratin smoothing famous in America, then infamous through the 2010-2011 formaldehyde controversy.
Also known asBB, Brazilian Blowout Original, Brazilian Blowout Zero (the aldehyde-free line). In the UK the generic phrase Brazilian blow dry is often confused with this specific US brand — they are related but not the same.

History and origin
Launched in the US around 2007, inspired by Brazil's escova progressiva culture, the Brazilian Blowout became the celebrity smoothingDOWN treatment of the late 2000s — the first system promising salon-finished hair the same day, no waiting period, no lifestyle rules. In 2010 Oregon's workplace safety agency tested the "formaldehyde-free" formula after stylists reported symptoms and found significant formaldehyde release; California's attorney general action and a class settlement followed, and the product continued with mandated warnings. The company later introduced Brazilian Blowout Zero, marketed as aldehyde-free. The episode reshaped the entire industry's labelling and pushed the market toward acid-based systems.
Popular years
2007-2010 the celebrity boom. 2010-2011 the controversy. 2012-2019 warnings era and the rise of "formol-free" rivals. Today: still on menus, alongside its Zero line, in a far more sceptical market.
Names across markets
This is a US brand name used in English almost everywhere. Useful mappings: UK — often (wrongly) used interchangeably with "Brazilian blow dry". Brazil — ironically not used; Brazilians say progressiva. Spanish markets — alaciado brasileno or cepillado brasileno appear as loose translations. France — lissage bresilien covers the whole category. Elsewhere the English brand name travels as-is. The misspelling "brazillian blowout" carries real search volume.
Chemistry
Original: liquid keratin system with an aldehyde component — the controversy centred on methylene glycol, which releases formaldehyde gas under flat-iron heat. Zero: marketed as no-aldehyde plant-derived bonding chemistry. As always, the back label and safety data sheet outrank the front label.
Label decoder
The names at the heart of this brand's story: methylene glycol, formalin, methanal — all formaldehyde in different clothing. A salon offering any keratin-family service should be able to show you the safety data sheet on request; hesitation is your answer.
What hair type is it for
Best for: frizzy, wavy, colour-treated hair wanting smoothness with body — this system deliberately keeps volume and movement. Works with care: highlighted and bleached hair, with strand test. Not for: anyone wanting real straighteningDOWN; anyone chemically cautious who has not seen the exact formula being used.
Pregnancy and breastfeeding
Given this brand's specific history, the guidance is firm: avoid aldehyde-linked systems entirely in pregnancy and breastfeeding, Zero included unless your doctor clears the exact formula. Salons should decline; good ones do.
Men, and minimum age
Fine for men — short hair makes it quick, frequent cuts make it short-lived. Minors: minimum 16 as with the whole keratin family.
Compatibility with previous chemistry
Friendly by design: over colour (same-day colour before treatment is the classic pairing), over highlights, over previous keratin. Over henna: strand test or decline. Over relaxerDOWN or straightening: usable as a smoothing top-up on lengths in experienced hands.
How to prepare
Nothing special — that was always the pitch. Colour first if colouring. Ask two questions when booking: Original or Zero, and may I see the safety data sheet.
Step by step in the chair
1. Clarifying wash.
2. Product applied section by section.
3. Blow-dry.
4. Flat-iron pass to seal.
5. Rinse at the basin — same visit.
6. Bonding mask, style, walk out finished. Around 90 minutes to two hours. No waiting period, no wash rules.
Results and longevity
Smooth, glossy, frizz-immune hair with movement, fading evenly over roughly 10-12 weeks. No demarcation line. Quarterly is the typical rhythm.
Brand landscape
This page is the brand. Category rivals worth comparing: Keratin Complex, Cadiveu, GK Hair, Cocochoco, Kerasilk — see the keratin treatment guide.
At-home kits vs salon
The brand sells aftercare retail, not the treatment itself — the in-salon system is professional-only. Anything sold online claiming to be the salon formula is a counterfeit red flag.
Home care
The easiest in the category: wash when you like with sulfate-free, salt-free products, protect from heat, mask weekly. The brand's own aftercare line exists; any quality keratin-safe routine performs the same job.
Climate performance
Its humidity resistance made its name — holiday hair is the use case. Salt and chlorine still shorten its life: pre-soak, rinse after, weekly mask. Hard water: monthly chelating wash keeps the gloss.
What can go wrong
Mostly trust failures rather than hair failures: undisclosed formulas, diluted product, uncertified salons trading on the famous name. Hair-side risks mirror the keratin family — heat damage on fragile bleached hair, toner shift on blondes. Verify the salon is an authorised provider; the brand maintains a locator.
Compared to
Keratin treatment — the generic family this brand made famous; classic versions demand the 72-hour rules this system removed. Brazilian blow dry — the UK's generic term, often a different product entirely. Nanoplastia — the "clean successor" positioning, stronger straighteningDOWN claim.
Questions
Is a Brazilian Blowout the same as a keratin treatment?
It is one specific branded keratin-family system, distinguished by its rinse-and-go protocol — no waiting period, no wash rules. Generic keratin treatmentsDOWN vary widely in chemistry and rules. In the UK, "Brazilian blow dry" usually means a generic keratin service, not this brand.
Does it contain formaldehyde?
The Original formula was found by US regulators in 2010 to release significant formaldehyde when heated, despite formaldehyde-free marketing — the defining controversy of the category. The Zero line is marketed as aldehyde-free. Ask which version your salon uses and request the safety data sheet.
How long does it last?
Around ten to twelve weeks, fading evenly with washing. Salt-free, sulfate-free aftercare, limited swimming exposure and weekly masking push it toward the upper end. There is no regrowth line — it simply washes out.
Can I wash my hair the same day?
Yes — that is the treatment's signature. Hair is rinsed and styled before you leave, and you can wash, tie, tuck and exercise immediately. If a salon gives you 72-hour rules, you are not receiving this brand's protocol.
Is it safe?
The honest answer: the Original's history is exactly why this guide teaches label reading. In a ventilated salon, with the Zero formula and full disclosure, most professionals consider the risk low. With undisclosed formulas, you are the ventilation system. Ask, verify, then decide.
Will it straighten my curls?
No — it will loosen, soften and de-frizz while keeping your wave or curl's shape and body. That volume-friendly result is the point. For genuine straightening, look at Japanese straightening or rebonding instead.
