A Brazilian blowout is a smoothing treatment in the keratin family, but it behaves a little differently on price and longevity, which changes your yearly total.
What it costs
Expect prices in the same band as standard keratin, commonly $150–$400 per session and more for long or dense hair. As with any keratin service, tip and travel push the real per-visit number higher, so a quoted $300 service is closer to $360 once you add a 20% tip.
How often you need one
A Brazilian blowout typically lasts about 10–16 weeks, so most people re-treat roughly every 3 months, around 4 times a year. That is a touch more often than a longer-lasting keratin smoothing service, which pushes the annual cost up: four $360 visits is about $1,440 a year before extras. That frequency is why it can dominate your keratin cost per year. If that cadence makes the salon expensive for you, an at-home kit routine shows how much a milder, do-it-yourself approach would save.
Brazilian blowout vs standard keratin
People use the names interchangeably, but the difference matters for your annual cost because it comes down to how long each one lasts:
- Brazilian blowout: a specific branded system, smooths without fully straightening, lasts about 10–16 weeks. Faster in the chair, but the shorter window means roughly 4 re-treats a year.
- Standard keratin (e.g. express or Cezanne-style): often lasts 12–24 weeks, so 2–3 visits a year is common. Higher per-session price, but fewer sessions can mean a lower yearly total.
How to stretch each treatment
- Wait the full 48–72 hours before the first wash so the smoothing sets
- Switch to a sulfate-free, sodium-chloride-free shampoo: salt strips the treatment fast
- Wash less often; every third day roughly doubles the life versus daily washing
- Rinse well after pools and the ocean, since chlorine and salt water shorten results
