Deciding where to get your hair done can feel like a lot. I have sat in both chairs, the quick Dominican blowout that gives you swingy hair for a week, and the longer salon visit for a Brazilian blowout that smooths frizz for weeks. If you are deciding between a Brazilian blowout and a Dominican blowout, here is the plain talk version so you can pick without second guessing.

Quick answer
A Dominican blowout is a heat styling technique, no chemical relaxers, that uses a roller set, a high tension blow dry, and a light flat iron for a silky finish that usually lasts about a week.
A Brazilian blowout is a keratin smoothing treatment that is applied, blow dried, then sealed with a flat iron. Results often last 10 to 12 weeks, sometimes 3 to 4 months with careful aftercare. Some smoothing products can release irritating fumes when heated, so ask your stylist about the exact product and ventilation.
What each one is
Dominican blowout, the technique
Wash, deep condition, set hair on large rollers, then a high tension blow dry with a concentrator, and a light pass with the flat iron if needed. It is temporary styling, not a chemical straightener, which is why curls bounce back after your next wash when you are gentle with heat. Most people get about a week of wear.
Brazilian blowout, the treatment
Your stylist applies a keratin based smoothing solution, blow dries, then seals with a flat iron. Results typically last 10 to 12 weeks, and many clients see three months or more with fewer washes and the right aftercare.
Brazilian blowout vs Dominican blowout, side by side
| Feature | Dominican blowout | Brazilian blowout |
|---|---|---|
| What it is | Heat styling technique, no chemical relaxers | Keratin smoothing treatment sealed with heat |
| Process | Wash, deep condition, roller set, high tension blow dry, light flat iron | Apply formula, blow dry, flat iron to seal |
| Longevity | About a week, longer if you keep it dry and wrap at night | About 10 to 12 weeks, sometimes 3 to 4 months with proper care |
| Finish | Light, bouncy, lots of movement | Sleeker, more humidity resistant, strong frizz control |
| Chemicals | No relaxers | Some formulas can release fumes when heated, ask about the brand and ventilation |
| Best for | Anyone who wants a temporary silk press look without committing to a treatment | High frizz, humid climates, or anyone who wants multi week smoothing |
| Main risks | Heat damage if overdone or too frequent | Fume exposure during application if ventilation is poor, ingredient sensitivity |
Cost, time, upkeep
Typical cost in the US
- Dominican blowout, about $35 to $90, depending on city and hair length.
- Brazilian blowout, about $150 to $350+, higher for very long or dense hair.
Always ask what is included, cut, mask, or take home products.
Time in chair
Plan on a couple of hours for the Dominican blowout, including wash, set, and that thorough blow dry. A Brazilian blowout usually runs longer because of application, processing, and sealing.
Aftercare
For Dominican styles, keep it dry, wrap at night, and avoid steam rooms and sweaty workouts if you want the full week.
For Brazilian blowout, use sulfate free shampoo, space out washes, and follow your stylist’s care notes.
If you want to stretch results between services, mix in low heat weeks, protective styles, and a solid heat protectant on any flat iron day. Helpful reads:

Safety and ingredients, what to ask your stylist
This is the part to take seriously. Some hair smoothing products can release irritating fumes when heated during blow drying and flat ironing. Ask exactly which formula your stylist uses, how the space is ventilated, and what protective steps they follow. If you are sensitive, pregnant, or just cautious, talk through alternatives before you book.
Dominican blowout vs Brazilian blowout, which lasts longer
If longevity is your tie breaker, a Brazilian blowout generally wins. Expect 10 to 12 weeks, sometimes 3 to 4 months with careful aftercare. A Dominican blowout is usually a one week style, sometimes longer if you baby it and avoid moisture.
How I decide for friends and for myself
- If I want a sleek look for an event or a short stretch, I book a Dominican blowout and wrap at night.
- If I am fighting humidity for a season, I consider a Brazilian blowout, but only with a salon that can show me the product label and walk me through ventilation.
- When I want no chemical treatments this week, I skip smoothing services and focus on deep conditioning and gentle heat. If I need a light boost between visits, I check my notes from an at home keratin experiment and adjust accordingly, see this quick overnight keratin diary.
FAQs, Dominican blowout vs Brazilian blowout
Which lasts longer, Brazilian blowout or Dominican blowout?
Brazilian blowout results usually last far longer, weeks to months, while a Dominican blowout is a one week style for most people.
Is a Brazilian blowout safe?
Safety comes down to the formula and how the salon handles ventilation. Ask what brand they use and how they keep the room safe, then decide based on your comfort.
Will my curls come back after a Dominican blowout?
Yes, because it is a heat styling technique, not a chemical straightener. Be mindful with heat to avoid damage over time.
Can I keep some wave with a Brazilian blowout?
Many stylists can finish with a bend or loose wave even after smoothing. Longevity varies with hair type and wash frequency.
