The keratin treatment family
covers every semi, demi -permanent smoothing treatment that coats and fills hair with protein, sealed in by a flat iron: the generic keratin treatment, the branded Brazilian Blowout, and the UK's Brazilian blow dry. All kill frizz, loosen curl and wash out over roughly three to five months with no regrowth line.
THE FAMILY EXPLAINED
Every member shares the same DNA, born from Brazil's escova progressiva: protein plus a fixing agent, ironed into the hair. What separates them is chemistry generation (aldehyde classics versus modern acid systems), protocol (72-hour rules versus rinse-and-go), and naming — the same service wears different clothes in every country. This family owns the global smoothing market because it delivers the most wanted result in hair: your hair, but behaving.
THE TREATMENTS IN THIS FAMILY
The keratin treatment guide — the complete honest guide to the core service, its chemistry, hair-type match, aftercare and everything that can go wrong.
The Brazilian Blowout story — the American brand that named the category, its same-day protocol, and the formaldehyde story every client deserves to know.
The Brazilian blow dry explained — what British menus actually mean, the "permanent blow dry" naming trap, and how to book one wisely in the UK.
Where it all began: the escova progressiva.
HOW TO CHOOSE WITHIN THE FAMILY
Want the longest track record and widest salon choice: generic keratin. Want zero lifestyle rules and same-day washing: the Blowout protocol or a modern acid system. In the UK and unsure what you were offered: read the Brazilian blow dry page first — the name tells you almost nothing until you ask which system is in the bottle. Damaged or bleached hair leaning gentler: consider hair botox instead; wanting more straightening power: nanoplastia.
FAMILY RULES THAT NEVER CHANGE
Sulfate-free and salt-free washing, colour before not after, strand tests on bleached hair, and the label decoder: formaldehyde hides behind methylene glycol, formalin and methanal on ingredient lists. A salon that can name its system instantly is a salon you can sit in.

FAQ
Q: Are all keratin treatments the same?
A: No — one family, several chemistries. Classic aldehyde systems smooth hardest with the strictest rules and the safety debate; modern acid and amino systems trade a little power for gentleness and same-day freedom. The name on the menu matters less than the ingredient list behind it.
Q: Which keratin treatment lasts longest?
A: Classic full-strength systems reach five months; rinse-and-go protocols like the Blowout run closer to three. Aftercare moves every version by weeks in either direction — salt-free washing, weekly masks and swim discipline are worth more than the brand choice.
Q: Is the keratin family safe?
A: Modern formol-free systems in ventilated salons are considered low risk for most people. The family's controversy belongs to formaldehyde-releasing formulas, which regulators continue squeezing out worldwide. Every treatment page in this family includes the full label decoder — read it before you book.
