If you live in San Antonio, you already know what summer does to your hair. From May through September, the humidity hovers near 90 percent and the heat index regularly pushes past 100 degrees. That combination is the enemy of smooth, frizz-free hair, and it's exactly why smoothing treatments like the Brazilian Blowout are consistently one of our most requested services at Got Hair? Color Salon. This isn't a trend for us — it's a practical solution for a city that genuinely needs it. Here's everything you should know before booking.
What Is a Brazilian Blowout?
A Brazilian Blowout is a professional smoothing treatment that works by coating the outside of the hair shaft with a liquid keratin solution. During the appointment, the formula is applied to clean, damp hair and then heat-sealed into the cuticle using a flat iron. That sealing step is what makes the results immediate — you leave the salon with smooth, frizz-free hair the same day, not after a waiting period.
Unlike some older smoothing treatments that required you to avoid water for several days post-service, the Brazilian Blowout allows you to wash your hair and style it normally right away. There's no awkward transition period, no restrictions on ponytails or clips, and no dramatic change in texture if you don't want one. The treatment smooths the cuticle, reduces frizz, and makes your hair significantly easier to style — without necessarily removing all of your natural wave or curl.
The liquid keratin formula used in a professional Brazilian Blowout is different from drugstore keratin products. Professional-grade treatments contain a higher concentration of the active ingredient, and the heat-sealing technique ensures that the keratin bonds to the hair shaft rather than sitting on top of it temporarily. The results are measurable, consistent, and backed by the skill of the person applying it — which is why you want a trained colorist handling this service, not a general salon that does it occasionally.
Brazilian Blowout vs. Keratin Treatment — What's the Difference?
This question comes up at nearly every smoothing consultation we do, and it's a fair one. The terms get used interchangeably online, but they describe two genuinely different services with different results and different timelines.
A Brazilian Blowout coats the outside of the hair shaft. The keratin sits on the surface of the cuticle and smooths it down, which is what eliminates frizz and reduces drying time. Because the treatment doesn't penetrate deeply into the hair's internal structure, it tends to last around 10 to 14 weeks. The results are significant — especially in high-humidity environments like San Antonio — but they're not permanent. Your natural texture gradually returns as the treatment grows out and washes out over time.
A keratin treatment, by contrast, penetrates deeper into the hair structure. It works on the cortex — the inner layer of the hair — rather than just the cuticle surface. This deeper penetration means longer-lasting results, typically three to five months. It also means that with repeated applications, a keratin treatment can progressively relax and straighten the hair over time in a way that a Brazilian Blowout won't.
Which one is right for you depends on what you're trying to accomplish. If your goal is frizz control and faster drying time while keeping your natural wave or curl pattern intact, a Brazilian Blowout is usually the better fit. If you're looking for significant straightening that lasts through an entire San Antonio summer and beyond, a deeper keratin treatment may serve you better. During your consultation, we'll assess your hair's texture, density, and condition to help you decide. You can also read the full comparison on our Brazilian Blowout service page.
Is a Brazilian Blowout Right for Your Hair?
The honest answer is that it's right for most hair types — with a few exceptions worth knowing about before you book.
Brazilian Blowouts work especially well for women with frizzy, wavy, or thick hair who spend significant time fighting humidity and drying time. If you leave the house with smooth hair and arrive wherever you're going looking like you've been standing in steam, you're a good candidate. The treatment essentially gives your cuticle a protective coating that keeps moisture from penetrating and causing that familiar puffing and frizzing effect.
Color-treated hair is absolutely compatible with Brazilian Blowouts. In fact, the treatment can help seal in your color and extend the time between color appointments. At Got Hair? Color Salon, where color is the foundation of everything we do, this is a point we emphasize often. Sonia and Wendy both recommend smoothing treatments to color clients who want to maintain vibrancy between appointments — the keratin coating helps protect the hair shaft and slow color fade. The one caveat: we generally recommend waiting at least two weeks after a fresh color service before adding a smoothing treatment, so both can work at their best.
Fine hair deserves a slightly more careful conversation. The Brazilian Blowout formula can be adjusted for finer textures, but it's easy to overdo it if you're not working with someone who knows what they're looking at. Too much product or too aggressive a heat application on fine hair can result in flatness rather than smoothness. We customize every treatment to your specific density and texture, which is why we always start with a consultation.
If you have very tightly coiled hair and your primary goal is significant straightening rather than frizz control, a different treatment — or a combination of services — may be more effective. We'll tell you that honestly in the consultation rather than upsell you on something that won't deliver what you're hoping for.
How Much Does a Brazilian Blowout Cost in San Antonio?
At Got Hair? Color Salon, Brazilian Blowout treatments range from $125 to $350, depending on your hair's length and density. That range is wide, and for good reason — a client with a short, fine bob and a client with thick, mid-back-length hair are not getting the same amount of product or the same amount of chair time.
When you see Brazilian Blowout prices around San Antonio, you'll notice significant variation. Some salons advertise entry-level prices that apply only to very short hair and go up steeply from there. Others charge a flat rate regardless of hair length. Neither approach is wrong, but it can make comparison shopping feel confusing.
What matters more than the number on a menu is whether the person applying the treatment has real experience with it. A smoothing treatment applied incorrectly — with the wrong amount of product, improper sectioning, or insufficient heat-sealing — won't last as long and won't look as good. For first-time smoothing clients, we require a brief consultation so we can examine your hair in person, give you an accurate price, and make sure a Brazilian Blowout is actually the right service for what you're trying to achieve. There's no charge for the consultation, and it makes the actual appointment go much more smoothly.
If you're weighing the cost, it helps to think about it in terms of time saved. Clients who get Brazilian Blowouts here regularly tell us their daily styling time drops from 45 minutes to under 15. In San Antonio's climate, that's a meaningful quality-of-life shift — and it lasts for three to four months between appointments.
How Long Does It Last?
With proper care, a Brazilian Blowout will last 10 to 14 weeks. That's the range we see most consistently at our salon, and it holds up well even in San Antonio's climate — with one important caveat about pool season.
The single biggest factor in how long your treatment lasts is shampoo. Sulfate-free shampoo is non-negotiable after a Brazilian Blowout. Sulfates are the harsh detergents in many conventional shampoos that create lather, and they also strip the keratin coating significantly faster than your natural growth and wear would. Switching to a professional sulfate-free formula isn't a minor preference — it's the difference between results that last 10 weeks and results that fade in four. We carry a curated selection of professional aftercare products in our online shop specifically for this reason.
Salt water and chlorine are the other major factors to watch. Both will accelerate the breakdown of the keratin coating. In a dry climate, this might not come up often. In San Antonio, where outdoor pool season runs from roughly April through October, it comes up constantly. If you're a regular pool user, we recommend rinsing your hair with clean water before swimming (saturated hair absorbs less chlorine), wearing a swim cap when possible, and rinsing and conditioning immediately after. Your treatment will still fade faster than it would without pool exposure, but these steps make a real difference.
UV exposure is also a factor that doesn't get enough attention. San Antonio's intense sun can degrade keratin treatments over time, similar to how it fades color. A UV-protective leave-in or styling product adds meaningful protection, especially during summer.
The Got Hair? Smoothing Process
Every smoothing appointment at Got Hair? Color Salon begins with a consultation, whether you've had a Brazilian Blowout before or not. We want to see your hair in person — not in a photo — before recommending a specific formula, treatment level, or application approach. Hair texture, density, porosity, and current condition all factor into how we customize the treatment.
Once we've talked through your goals and assessed your hair, the actual treatment process takes approximately two to three hours, depending on hair length and density. Here's what that time looks like: your hair is shampooed with a clarifying wash to remove buildup, then the keratin solution is applied in sections from root to tip. After a processing period, the hair is blown dry and flat-ironed in small sections to heat-seal the keratin into the cuticle. That flat-iron pass is the key step — it's where the treatment locks in, and it requires attention to temperature, tension, and timing to get it right.
We use professional-grade products and customize the formula to your hair's specific needs. Fine hair gets a lighter application. Thick, coarse, or highly porous hair gets a more robust treatment. We don't apply the same product in the same way to every client, because every head of hair is genuinely different — and the results reflect that level of attention.
After the treatment is complete, we'll blow-dry and style your hair so you can see the results immediately. You'll leave the salon with smoother, shinier hair that already looks different from when you walked in.
Before and After Your Treatment
A few things to know before your appointment. If you're planning to have a color service and a Brazilian Blowout in the same general timeframe, schedule the color first and wait at least two weeks before the smoothing treatment. Doing both in the same session — or too close together — can compromise both results. Fresh color needs time to fully settle before you add another chemical process on top of it.
Come to your appointment with clean hair if possible, though we'll clarify-shampoo at the salon regardless. Avoid heavy styling products, oils, or dry shampoo on the day of your appointment, as these can interfere with product absorption.
After your treatment, the 72-hour rule no longer applies to traditional Brazilian Blowout formulas — you can wash your hair, wear it in a ponytail, and style it normally right away. However, we still recommend being gentle for the first 24 hours: light activity, minimal sweating, and avoiding anything that would create a hard crease in your hair while the treatment finishes bonding.
For ongoing aftercare, the essentials are straightforward: sulfate-free shampoo and conditioner every wash, a UV-protective product during San Antonio's long sunny season, and limited salt water and chlorine exposure. We can walk you through specific product recommendations at your appointment, and you can browse our professional picks in the shop. Planning color around a smoothing treatment is also covered in our wedding hair color timeline, which applies to any big event.
Why San Antonio Is Perfect (and Challenging) for Smoothing Treatments
San Antonio sits in a part of Texas where the climate creates genuinely difficult conditions for hair. Summer relative humidity regularly reaches 85 to 90 percent, which means the air is nearly saturated with moisture for months at a time. When hair cuticles are open or rough — which happens naturally with heat styling, chemical processing, and environmental wear — that atmospheric moisture gets absorbed into the hair shaft and causes the familiar swelling that creates frizz.
A Brazilian Blowout works against this by flattening and sealing the cuticle so it can't absorb moisture as readily. In a dry climate, the results are pleasant but not dramatic. In San Antonio, the results feel remarkable because the problem you're solving is so constant and so significant. Clients who've gotten this treatment in other cities and then tried it here regularly tell us the difference is more noticeable than they expected.
Hard water is another San Antonio-specific factor that doesn't get discussed enough. Much of the city's water supply comes from the Edwards Aquifer, which produces hard water with a high mineral content. Over time, hard water deposits build up on the hair shaft, contributing to dryness, dullness, and increased porosity. Higher porosity means the hair absorbs and loses moisture more rapidly — which accelerates frizz and can shorten the life of smoothing treatments. A clarifying treatment or a chelating shampoo used periodically can help manage this, and it's something we discuss with clients who notice their treatments fading faster than expected.
UV intensity is the third piece of the puzzle. San Antonio's sun exposure over a long outdoor season degrades both color and keratin treatments faster than clients from cooler, cloudier climates expect. We factor all of this into our aftercare recommendations. The goal is results that hold up through the full lifespan of the treatment, not just the first few weeks.

Frequently Asked Questions
How long does a Brazilian Blowout last in San Antonio's humidity?
With proper aftercare — sulfate-free shampoo, limited salt water and chlorine exposure, and a UV-protective product during our long sunny season — a Brazilian Blowout typically lasts 10 to 14 weeks in San Antonio. The humidity itself doesn't dramatically shorten the treatment's life if the cuticle is properly sealed during the service. What shortens it most is using the wrong shampoo and heavy pool exposure during summer. Clients who follow the aftercare protocol consistently tend to land on the longer end of that range.
Can I get a Brazilian Blowout if my hair is color-treated?
Yes, and in many cases we recommend it specifically for color-treated hair. The keratin coating helps seal the hair shaft and slow color fade, which extends the life of your color between appointments. The timing matters: we ask that you wait at least two weeks after a fresh color service before getting a smoothing treatment. This gives your color time to settle and ensures both services perform at their best. If you're unsure about the right sequence for your hair, that's exactly what consultations are for.
What's the difference between a Brazilian Blowout and a keratin treatment?
A Brazilian Blowout coats the outside of the hair shaft for immediate smoothing results that typically last 10 to 14 weeks. Keratin treatments penetrate deeper into the hair structure, produce longer-lasting results of three to five months, and can progressively relax and straighten hair with repeated applications. The Brazilian Blowout is generally better for clients who want frizz control while preserving their natural wave or curl. Keratin treatments suit clients looking for more dramatic or lasting straightening. We carry both and will help you choose the right option based on your hair type and goals during your consultation.
