If you’re thinking about getting a Brazilian blowout, you might be wondering: how long does a Brazilian blowout take? A Brazilian Blowout usually takes about 1.5 to 3 hours to complete. This appointment duration can vary depending on several factors such as hair type and stylist’s experience. This hair treatment makes your hair smooth, shiny, and easy to manage – but it also takes some time at the salon. In this article, we’ll explain how long the process usually takes, what affects the timing, and what you can expect during your appointment.
What Is a Brazilian Blowout?
A Brazilian Blowout is a popular keratin smoothing treatment designed to make hair smoother, shinier, and noticeably less frizzy. It works by applying a keratin-based formula that forms a protective layer around each strand, helping to seal in moisture and smooth the hair’s surface. This professional hair smoothing service is ideal for people with frizzy, dry, or hard-to-manage hair. After the treatment, hair becomes easier to brush, style, and maintain, with results typically lasting two to three months, depending on washing frequency and hair care products used.
This semi-permanent hair smoothing solution uses liquid keratin to reduce frizz, tame flyaways, and enhance shine without permanently changing the hair’s natural structure. Unlike traditional straightening methods, this salon keratin treatment allows you to maintain your natural waves or curls while achieving a softer, healthier, and more manageable finish. It’s a great option for anyone who wants smooth, silky hair without sacrificing movement or a natural look.

How Long Does a Brazilian Blowout Take?
A Brazilian Blowout usually takes about 90 minutes to 3 hours to complete. It’s actually one of the faster smoothing treatments available. You might be wondering: How long does keratin treatment take?
Traditional keratin treatments can take two to four hours to complete and often require you to wait several days before washing your hair. In contrast, a Brazilian Blowout offers no downtime, allowing you to wash, style, or tie up your hair immediately after the treatment.
Compared to standard keratin smoothing services, this option is faster and more flexible, making it ideal for those with busy schedules who want smooth, manageable hair without waiting days to enjoy the results.
- Short hair: about 90 minutes.
- Long or very thick hair: up to 3 hours.
The exact time depends on a few things:
- Your hair length – Long hair takes more time than short hair.
- Your hair thickness – Thick or curly hair needs more work to smooth out.
- Your hair condition – Damaged or very frizzy hair may take longer.
- The stylist’s experience – A skilled stylist might work faster and more efficiently.
During the treatment, your stylist will wash your hair, apply the smoothing solution, blow-dry it, and then flat iron it in small sections. The process takes time, but the result is smooth, shiny, easy-to-manage hair. So, if you’re planning to get one, make sure to have at least 2 to 3 hours free – just to be safe!
How long does a Brazilian Blowout take at home?
If you’re doing it yourself, it might take a bit longer – usually about 2 to 4 hours, especially if you’re not used to working with hair treatments. At home, you’re handling every step on your own, so it may require more time and patience. No matter where you do it, make sure to allow enough time so the process can be done properly for the best results.
Brazilian Blowout Before and After
Before the treatment, your hair might be frizzy, dry, or hard to control – especially when the weather is humid. After getting a Brazilian Blowout, your hair will look smoother, shinier, and easier to take care of. It helps reduce frizz and makes blow-drying quicker. Many people say their hair feels softer and healthier after the treatment. The results are not forever, but with good care, they can last for a few months.
Brazilian Blowout side effects
A Brazilian Blowout can make your hair smooth and shiny, but it may also have some side effects. During the treatment, the strong smell from the chemicals can cause eye, nose, or throat irritation, especially if the room is not well-ventilated. After the treatment, your hair might feel dry or become weak if you do it too often or don’t take care of it properly. Some people may also get an itchy or irritated scalp. It’s a good idea to talk to your hairstylist first and make sure the salon is safe and well-ventilated.
How Much Is a Brazilian Blowout?
The cost of this professional keratin smoothing treatment can vary depending on the salon and your hair type. On average, prices range from $200 to $400. If you have long or thick hair, the cost may be higher since the service requires more time and product. To avoid surprises, it’s always a good idea to ask for a price estimate before booking your appointment.
If you’re ready to try this frizz-reducing hair service, the next step is finding a reputable salon near you. Searching online for local keratin smoothing treatments and reading customer reviews can help you identify salons with satisfied clients. Look for a clean space with proper ventilation and professional-grade products, and don’t hesitate to call ahead to ask questions before scheduling your visit.

A Breakdown of the Brazilian Blowout Procedure
If you’re wondering what actually happens during a Brazilian Blowout, here’s a simple, step-by-step guide to help you understand the process:
1. Hair is Washed
The first step is to wash your hair using a special clarifying shampoo. This shampoo deeply cleans your hair and removes any dirt, oil, or leftover hair products. It also opens up the hair cuticles, so the Brazilian Blowout treatment can be absorbed better. After this step, your hair will feel super clean – but a little rough or dry, which is normal at this stage.
2. Blow-Dry
Next, your stylist will blow-dry your hair completely until it’s 100% dry. This helps prepare your hair for the smoothing treatment. Drying also makes it easier for the stylist to apply the product evenly to each section.
3. Treatment is Applied
Now comes the key part – the Brazilian Blowout solution is applied to your hair in small sections. This product is made to coat and protect your hair, while making it smooth and shiny. Your stylist will carefully comb it through to make sure every strand is covered. You might notice a bit of smell at this stage, but it usually isn’t strong.
4. Blow-Dry Again
After the treatment is fully applied, your stylist will blow-dry your hair again. This helps set the product into your hair. This step takes some time, especially if you have thick or long hair.
5. Flat Ironing
Once your hair is dry, the stylist will use a flat iron (hair straightener) on small sections of your hair. This step is very important – it seals the treatment into the hair using high heat. It also gives your hair that super sleek and glossy finish. The stylist may go over each section several times to make sure it’s perfectly smooth.
6. Final Rinse (Sometimes)
Some stylists include a rinse-and-condition phase, where any excess product is rinsed out and a deep conditioner is applied. In some salons, your hair may be rinsed again to remove any leftover product. After rinsing, a deep conditioning mask might be applied to help nourish and protect the hair. Not all stylists do this step – it depends on the brand of treatment they use.
7. Style and Finish
Finally, your hair is dried and styled one last time. Now, your hair should feel much smoother, shinier, and softer, with little to no frizz. The best part? You can enjoy low-maintenance, easy-to-manage hair for weeks after the treatment.

How Long Does a Brazilian Blowout Last?
A Brazilian Blowout usually lasts around 2 to 3 months, depending on how you take care of your hair. If you wash your hair too often or use shampoos with sulfates, the treatment will fade faster. On the other hand, if you use sulfate-free products and avoid washing your hair every day, the results can last longer. Your hair type also matters – people with thicker or curlier hair may notice the smooth effect wears off a bit sooner.
Heat styling, swimming in salt water or chlorine, and harsh hair products can also reduce how long the treatment lasts. To keep your hair smooth and shiny for as long as possible, it’s best to use gentle products and protect your hair from damage.
How long does a Brazilian Blowout last on curly hair? For curly or very textured hair, the treatment may not last quite as long as it does on straight or fine hair. This is because curls can slowly come back as the treatment fades. On average, it may last around 6 to 8 weeks on curly hair, though this depends on your hair type and care routine. Even as it wears off, your curls may still feel softer, smoother, and easier to manage than before.

How to Care for Hair After a Brazilian Blowout
To keep your Brazilian Blowout looking good for as long as possible, you need to take care of your hair the right way. First, use a sulfate-free shampoo and conditioner – these are gentle and won’t wash away the treatment too quickly. Try not to wash your hair too often; 2–3 times a week is enough. When you style your hair with heat tools like a flat iron or curling wand, always use a heat protectant spray to avoid damage.
If you go swimming, protect your hair by wearing a cap or rinsing your hair right after you swim, especially in salt water or chlorine. Also, avoid strong hair products like hairspray or dry shampoo that may build up over time. With the right care, your hair will stay smooth, shiny, and easy to manage for weeks.
