Charleston humidity can be relentless. For a lot of women and men, stepping outside for five minutes can undo a blowout — frizz, puffiness, and loss of smoothness can happen fast in our coastal air.
That’s why keratin treatments are so popular here… but not all results are created equal.
At Salon International, my go-to system is Pure Brazilian, and here’s why — plus what makes keratin results last longer in Charleston’s climate.
The Two Pure Brazilian Options I Offer
1) Smoothing Treatment (Frizz Control | About 6–7 Weeks)
This option dramatically reduces frizz while keeping natural movement and body.
Best for:
- Clients who like their curl or wave pattern
- Softer, more natural-looking smoothness
- Anyone battling Charleston’s everyday humidity
2) Straightening Treatment (Smoother + Straighter | About 3–4 Months)
This option delivers a sleeker finish that lasts longer and can reduce daily styling time.
Best for:
- Coarse or resistant hair
- Stronger humidity protection
- Clients who want a straighter, longer-lasting result
Why Keratin Treatments Sometimes Fail (Especially in High Humidity)
In Charleston, humidity exposes weak technique fast. Here’s what truly determines whether a treatment lasts weeks… or months:
✔ Proper Saturation
The product must be applied evenly throughout the hair — not rushed, not under-applied.
✔ Blow-Dry Technique
Brush choice, tension, and direction matter. The cuticle must be aligned before flat ironing begins.
✔ Flat Iron Passes Per Subsection
Too few passes and the treatment won’t seal properly. Too many passes can stress the hair unnecessarily.
Precision matters.
✔ Complete Manipulation of the Hair
Sectioning, tension control, and consistent heat are the difference between “okay” and flawless.
When Can You Shampoo After Pure Brazilian?
One benefit of Pure Brazilian is that same-day shampooing is allowed.
However, in my professional experience, I recommend waiting 24–48 hours before washing to allow maximum bond setting and longevity — especially in Charleston’s humidity.
It’s not required by the manufacturer, but I’ve found it gives the most consistent, long-lasting results.
The Home Care That Protects Your Results
Using the wrong shampoo is one of the fastest ways to shorten keratin results.
I recommend:
- Pure Brazilian maintenance shampoo
- Pure Brazilian maintenance conditioner
- Weekly deep conditioning masque
Using a weekly deep conditioning masque helps maintain softness, strength, and shine — especially in Charleston’s humidity.
Humidity isn’t going anywhere in Charleston — but frizz doesn’t have to win.
