KATIVA Brazilian Post Straightening Treatment Kit — 3-Step Shampoo, Conditioner & Mask with Vegetal Keratin & Hyaluronic Acid, Sul

KATIVA Brazilian Post Straightening Treatment Kit is a three-step at-home maintenance system (shampoo, conditioner, mask) formulated with Keraliss Complex—vegetal keratin and hyaluronic acid—to help preserve and extend the smooth, straight results of professional treatments.

After a salon Brazilian or keratin straightening, the right daily products make the difference between short-lived results and weeks of manageable, frizz-resistant hair. This kit combines a sulfate-free shampoo, a balancing conditioner, and an intensive mask designed to hydrate, reinforce the hair fiber, and shield strands from humidity. The Keraliss Complex uses plant-derived keratin together with hyaluronic acid to add moisture and structure without weighing hair down, helping maintain a sleek finish between touch-ups.

How does this kit help keep hair straight longer?

The formulation focuses on moisture balance and fiber reinforcement, which help maintain the alignment created by professional straightening. Regular use supports reduced frizz and smoother lengths, which can preserve the straightened look for several additional weeks compared with untreated hair.

• Vegetal keratin helps rebuild and reinforce weakened hair fibers.
• Hyaluronic acid delivers targeted hydration to prevent dryness and breakage.
• Sulfate-free cleansing avoids stripping treatments that can relax straightened results.
• Conditioning and mask steps add slip and control that reduce frizz from humidity.

What is included and how do I use each step?

The kit contains a shampoo to cleanse gently, a conditioner to detangle and restore softness, and a mask for deeper replenishment. Use them as a routine: cleanse, condition, and treat, adjusting mask frequency based on hair porosity and styling needs.

• Shampoo: apply to wet hair, gently massage, then rinse to remove residues without harsh sulfates.
• Conditioner: apply mid-lengths to ends, leave 1–3 minutes, then rinse to seal and smooth cuticles.
• Mask: apply once or twice weekly for 5–10 minutes on damp hair for intensive hydration and strength.

Is this safe for colored, sensitized, or chemically treated hair?

The formulas are crafted to be gentle on hair that has undergone color or straightening treatments. Free of added salts and sulfates, the trio aims to protect the treated fiber while delivering conditioning benefits appropriate for processed hair.

• Sulfate-free and salt-free to minimize additional stress on treated hair.
• Vegan formulation without added gluten or animal-derived keratin.
• Designed to work alongside professional straightening without undoing salon results.
• Results may vary by hair type, previous treatments, and maintenance routine.

How does Keraliss Complex improve hair feel and resilience?

Keraliss combines plant-based keratin to reinforce the structural integrity of the fiber with hyaluronic acid to attract and hold moisture. Together they improve manageability, reduce roughness, and help hair retain a polished appearance between straightening services.

• Plant keratin targets weak points in the strand for added strength.
• Hyaluronic acid improves moisture retention for smoother cuticle alignment.
• Leaves hair softer and easier to style while minimizing static and flyaways.

Who this kit is for: ideal for anyone who has had a Brazilian or keratin straightening and wants an at-home maintenance routine to extend salon results. It suits colored or chemically treated hair that needs gentle cleansing, targeted hydration, and anti-frizz protection without sulfates or harsh salts. If you seek a vegan-friendly set that emphasizes fiber repair and humidity resistance to keep hair smoother between appointments, this three-step KATIVA kit is designed for you.
