The average price ranges between $150 and $500, depending on your hair length, texture, and the salon you choose. At Salon D in Dallas, our professional keratin smoothing treatments typically cost between $250 and $400, providing months of smooth, frizz-free, glossy hair with long-lasting shine and manageability.
As a Certified hair specialist at Salon D in Dallas with years of experience in advanced smoothing treatments, I’ve seen how transformative the right keratin system can be for all hair types.
 In this blog, I’ll share what is a keratin treatment is, how much it costs, what factors affect hair keratin pricing, how long results last, and professional tips to maintain your silky, frizz-free finish based on real client results at our Dallas salon.
 What Is a Keratin Hair Treatment?
A keratin treatment, often referred to as a Brazilian blowout or keratin hair straightening treatment, is a professional smoothing process that infuses your hair with a keratin-rich formula.
 Since keratin is the natural protein that makes up your hair’s structure, this treatment works by coating each strand with a protective layer that smooths frizz, adds shine, and reduces curl.
During the service, your stylist carefully applies the keratin solution and allows it to process for 1 to 4 hours, depending on your hair’s texture and thickness. The hair is then blow-dried and sealed with a flat iron, locking the product into the cuticle for long-lasting, silky results.
Keratin Treatment CostÂ
The cost of a keratin treatment typically ranges between $150 and $500, depending on several factors, including your hair length, texture, current condition, and the stylist’s expertise. Prices can also vary based on the salon’s reputation and location. On average, a keratin complex treatment lasts anywhere from 1 to 6 months, leaving your hair noticeably smoother, shinier, and frizz-free with consistent care and proper aftercare products.
| Hair Length | Keratin Treatment Price Range | Salon D Price |
| Short (above shoulders) | $150 – $300 | $200+ |
| Medium (shoulder-length) | $200 – $350 | $250+ |
| Long (past shoulders) | $250 – $450 | $325+ |
| Very Long (mid-back and beyond) | $300 – $500 | $400+ |
At Salon D, I always start with a personal hair consultation to assess your texture, density, and current condition. This helps us recommend the best keratin system for your needs , from gentle, formaldehyde-free options to deep-smoothing, humidity-resistant formulas perfect for Texas weather.
Factors That Affect Keratin Treatment Cost
Every head of hair is unique, which is why pricing varies slightly from client to client. The main factors that affect the total cost include:
1. Hair Length & Thickness
Longer, thicker, or coarser hair requires more product and longer application time, naturally increasing the price.
2. Type of Keratin Formula
At Salon D, we use premium keratin and smoothing systems that are formaldehyde-free, gentle, and safe even for color-treated hair. Cheaper salon products may lower the price but also the quality and longevity of your results.
3. Stylist Experience
Keratin treatments require precise timing, temperature control, and sectioning. Having a trained professional stylist perform the service ensures consistent, smooth, and safe results — without damaging your hair.
4. Salon Reputation & Location
High-end salons in major cities like Dallas typically charge more than suburban salons — but that’s often because they use higher-quality products, advanced techniques, and prioritize client safety.
How Long Does a Keratin Treatment Last?
With proper care, your keratin treatment can last anywhere from 3 to 6 months. Longevity depends on your hair type, the frequency of washing, and the products you use at home.
To keep your results looking their best, I recommend:
- Using sulfate-free, keratin-safe shampoos
- Avoiding chlorine or saltwater
- Minimizing heat styling
- Getting a touch-up every 4–6 months
How Long Does a Keratin Appointment Take?
Plan to spend about 2 to 4 hours in the salon chair. Here’s how it typically works at Salon D:
- Clarifying shampoo to remove buildup.
- Keratin solution application on clean, towel-dried hair.
- Processing time (30–60 minutes, depending on formula).
- Blow-drying and flat ironing to seal the keratin into the strands.
- Finishing style and aftercare recommendations.
We take our time to ensure that your results are even, silky, and perfectly sealed from root to tip.
Are Keratin Treatments Safe?
Yes, when done professionally with quality products. At Salon D, we only use low-fume, formaldehyde-free keratin formulas that are safe and gentle for your scalp, skin, and hair.
While some older keratin systems used harsh chemicals, today’s professional-grade formulas are much safer and healthier — especially when applied by an experienced stylist who controls heat exposure and product quantity.
If you have color-treated, highlighted, or chemically processed hair, we’ll adjust the formula and heat settings accordingly to maintain your hair’s integrity.
Keratin Treatment vs. Other Hair Straightening Options
| Treatment Type | Effect | Lasts For | Damage Level |
| Keratin Treatment / Brazilian Blowout | Smooths, adds shine, reduces frizz | 3–6 months | Minimal |
| Chemical Relaxer / Straightener | Permanently straightens hair | Permanent | High |
| Hair Botox Treatment | Hydrates, restores shine | 2–3 months | None |
How to Find the Best Hair Salon Near You for a Keratin Treatment?
Choosing the right salon makes all the difference in how your keratin treatment turns out. To ensure you get smooth, long-lasting results, follow these expert tips:
- Look for experience: Choose a stylist who specializes in keratin or smoothing treatments and understands how to tailor the process to your hair type.
