I found the only shampoo that preserves keratin treatments, extends results, and keeps hair flawless with ionic bonding.
This shampoo line is my holy grail for keratin-treated hair. It actively preserves my treatment, extends its effects for months, and maintains shine and strength through ionic bonding technology, unlike harsh products.
This is a review from Amazon.com about product:
Brazilian Blowout Anti-Frizz Shampoo & Conditioner,2 count (Pack of 1)

If you do Keratin or Brazilian hair treatments, now and again, this is the ONLY line of Shampoo,
Conditioner (…and their Ionic Bonding Spray) that you should be using. It preserves & extends the treatments and keeps your hit in tip-too shape. (Forget O-plex, which is not comparable nor meant to be used frequently)
Shampoo Basics & Tips
Understanding Keratin and Brazilian Hair Treatments
Keratin treatments (including Brazilian blowouts) are semi-permanent hair-smoothing procedures that infuse keratin protein into hair shafts. They reduce frizz, add shine, and last 3-6 months. Special sulfate-free shampoos like the reviewed product are essential because regular shampoos strip keratin bonds, shortening treatment life.
Ionic Bonding Technology Explained
The "Ionic Bonding Spray" mentioned uses charged ions to seal hair cuticles. This locks in moisture, smooths frizz, and reinforces keratin treatment integrity. Unlike standard conditioners, ionic products create electrostatic bonds that resist humidity and heat damage.
Why Avoid O-plex?
O-plex is a protein-replenishing treatment containing high-concentration keratin. The review warns against frequent use because over-application can cause protein overload—making hair brittle. It's designed for occasional repair, not daily maintenance like this shampoo line.
Daily Care for Treated Hair
Post-treatment hair requires: 1) Sulfate-free formulas to preserve keratin, 2) Low pH shampoos (under 5.5) to maintain cuticle closure, 3) Weekly deep conditioning. Avoid chlorine, saltwater, and high-heat styling to extend results.
Common Keratin Treatment Mistakes
Top errors include washing too soon after treatment (wait 72 hours), using volumizing shampoos (they lift cuticles), and towel-drying aggressively (causes frizz). Always pat hair dry with microfiber towels.
FAQs: Keratin Hair Care
Q: Can I use regular conditioner after keratin?
A: No—standard conditioners contain sulfates or silicones that degrade keratin. Use paired systems like this shampoo/conditioner duo.
Q: How often should I wash keratin-treated hair?
A: Limit to 2-3 times weekly with sulfate-free products to maximize longevity.
Q: Why does my treatment fade faster?
A: Hard water minerals, sweat, or incorrect products accelerate fading. Chelating shampoos (monthly) remove buildup.
