A keratin treatment smooths frizz, adds shine and cuts your blow-dry time. If Dallas humidity turns your hair puffy by lunch, it can make a big difference. Most results last about 3 to 5 months with good aftercare.
At Capelli Salon in North Dallas, every keratin treatment starts with a free consultation. We look at your hair, ask how smooth you want it and pick the right option for you. Clients rate us 4.6 stars across 273 reviews. You will find us at 19177 Preston Rd, Suite 165, Dallas.
What Is a Keratin Treatment?
Keratin is a protein that your hair is already made of. A keratin treatment coats the outside of each strand with a smoothing formula. Your stylist then seals it in with a flat iron.
The result is softer, shinier hair with far less frizz. It does not change your hair’s structure, so it slowly washes out over a few months. As it fades, your natural texture comes back gently, with no harsh regrowth line.
Keratin Treatment Options at Capelli Salon Dallas
We offer three ways to smooth your hair. All of them use the Keratin Complex system. You can read more on our Keratin Complex smoothing treatment page.
| Option | Best for | How long it lasts |
|---|---|---|
| Keratin Smoothing Treatment | Maximum frizz control on thick, frizzy or wavy hair | About 3 to 5 months |
| Express Blow Out | A quick refresh before a trip or a big event (about an hour) | Up to 6 weeks |
| Personalized Smoothing | Less frizz while keeping some wave or volume | Depends on the formula we choose |
Not sure which one fits? That is what the consultation is for. We will recommend one option, and explain why.
Is a Keratin Treatment Right for You?
Keratin is a great fit if you:
- Fight frizz every day, especially in humid weather
- Spend a long time blow-drying or flat-ironing
- Want soft, shiny hair that still moves
- Have color-treated hair and want it to look glossy
- Want smoother hair without a permanent change
Keratin may not be the best choice if you want pin-straight hair forever. In that case, compare it with Japanese straightening in our guide to Japanese relaxer vs keratin, or see our Japanese hair straightening service.
Keratin vs Brazilian Blowout vs Japanese Straightening
These three services are often mixed up. Here is how they compare.
| Keratin treatment | Brazilian blowout style smoothing | Japanese straightening | |
|---|---|---|---|
| Main result | Smooth, frizz-free, softer waves | Smooth with more movement | Pin-straight |
| Lasts | About 3 to 5 months | Usually a few months | Permanent on treated hair |
| Changes hair structure? | No | No | Yes |
| Regrowth line | No | No | Yes, as hair grows |
Brands and formulas differ, so these are general guides. Your stylist will explain what to expect for your hair.
What Happens at Your Keratin Appointment
- Free consultation. We check your hair’s texture, thickness and color history, and agree how smooth you want it.
- Wash and prep. We cleanse your hair so the treatment can grip each strand.
- Apply and seal. We apply the formula section by section, blow-dry it, then flat-iron to seal it in.
- Finish and aftercare. We style your hair and give you a simple routine to follow at home.
The Express Blow Out takes about an hour. A full smoothing treatment takes longer. The time depends on how long and thick your hair is, and we will give you an estimate before you book.
Keratin Aftercare: How to Make It Last
Good aftercare is the biggest reason a treatment lasts 5 months instead of 3. Follow these steps.
- Follow your stylist’s advice on when to first wash, tie or clip your hair.
- Use a sulfate-free shampoo and conditioner.
- Wash two or three times a week, not every day.
- Rinse your hair after swimming in a pool or the ocean.
- Use a heat protectant when you style.
- Sleep on a silk or satin pillowcase to cut friction.

Is a Keratin Treatment Safe?
For most people, yes, when a trained stylist follows the product instructions. Some smoothing products can release formaldehyde when they are heated. The FDA suggests asking your salon what a product contains, and we are always happy to tell you.
If you are pregnant, nursing or have a sensitive scalp, talk to your doctor first. Then let us know at your consultation so we can plan around it.
How Much Does a Keratin Treatment Cost in Dallas?
The price depends on the option you choose and on your hair’s length and thickness. Long, thick hair needs more product and more time. You will get a clear price at your free consultation, before any work starts.

Frequently Asked Questions
How long does a keratin treatment last?
Most keratin treatments last about 3 to 5 months with good aftercare. The Express Blow Out lasts up to 6 weeks. Sulfate-free shampoo and fewer washes help it last longer.
Does a keratin treatment damage your hair?
Not when it is done correctly and not too often. The treatment uses heat to seal in the formula, so we space treatments out and check your hair first.
Can I get keratin on colored or blonde hair?
Yes. It is often best to color first and smooth after, so your shade looks fresh and glossy. We check your hair’s condition at your consultation.
Will keratin make my hair straight?
Keratin smooths frizz and softens waves, but it usually does not make curly hair pin-straight. For permanently straight hair, ask about Japanese straightening.
Is keratin good for curly hair?
It can be, if you want less frizz and easier styling. Your curls will usually soften rather than disappear. Personalized Smoothing lets you keep more of your curl.
