KATIVA Brazilian Post Straightening Treatment Kit – 3-Step Sulfate-Free System with Vegetal Keratin & Hyaluronic Acid for Up to 18

KATIVA Brazilian Post Straightening Treatment Kit is a three-step sulfate-free system (shampoo, conditioner, mask) formulated to help extend the look and manageability of Brazilian or keratin-straightened hair for up to 18 weeks when used as directed. This kit combines the brand's Keraliss Complex—vegetal keratin and hyaluronic acid—to target hydration, strengthen the fiber, and control frizz between salon sessions. Designed for daily maintenance after a professional straightening service, the products are vegan, cruelty-free and free of sulfates, added salt and gluten to keep treated hair gentle and longer-lasting.

How does this kit help hair stay straighter longer?

Each step works together to protect the results of a professional straightening treatment by minimizing the mechanical and environmental stresses that make hair revert to its natural texture. The system cleanses without harsh sulfates, replenishes moisture, and seals the hair surface, helping to preserve the straightened shape and reduce frizz.

• Shampoo: mild, sulfate-free cleansing that preserves chemical treatments.
• Conditioner: restores softness and detangles to maintain sleek lengths.
• Mask: deeper hydration to reinforce hair fiber and smooth cuticles.
• Keraliss Complex: vegetal keratin plus hyaluronic acid for strength and moisture balance.

What improvements should I expect with regular use?

With routine at-home use, you can expect a smoother appearance, reduced frizz and more manageable hair that retains a salon-like finish between professional appointments. Results vary by hair type and prior treatments, but many users report longer-lasting straightness and improved texture.

• Reduced frizz and better humidity resistance.
• Improved softness and combability of lengths.
• Stronger, more resilient hair fiber over repeated use.
• Extended visual straightness—up to 18 weeks for some users.

Is the formula safe for colored or sensitized hair?

The kit is formulated without sulfates and added salt, making it suitable for hair that has been colored, chemically treated or sensitized. Its gentle surfactants and vegan ingredients aim to maintain the health of treated hair while supporting the longevity of straightening treatments.

• Sulfate-free cleansing minimizes color and treatment stripping.
• No added gluten or salt to avoid unnecessary fiber stress.
• Vegan and cruelty-free formulation for conscientious care.

How should I use the three steps for best results?

Use the shampoo to cleanse and remove buildup, follow with the conditioner to detangle and smooth, and apply the mask once or twice weekly for deeper reconstruction and moisture. Consistent use as part of your post-straightening routine supports longer-lasting, more disciplined hair.

• Shampoo: apply to wet hair, lather gently, rinse thoroughly.
• Conditioner: apply mid-lengths to ends, leave 1–2 minutes, rinse.
• Mask: use weekly, leave 5–10 minutes for intensive hydration, then rinse.
• Finish with heat protection when styling to preserve results.

Who is this for? This kit is intended for anyone who has had a Brazilian or keratin straightening treatment and wants to maintain salon results at home. It suits color-treated or chemically processed hair that needs gentler cleansing, targeted hydration and anti-frizz support. If you seek a vegan, sulfate-free maintenance routine to keep hair smoother and more manageable between salon appointments, this KATIVA three-step system is formulated for that purpose.
