KATIVA Brazilian Post-Straightening Kit — 3-piece Shampoo, Conditioner & Mask with Hyaluronic Acid

KATIVA Brazilian Post Straightening Treatment Kit is a three-step maintenance system — shampoo, conditioner and mask — formulated with vegetal keratin and hyaluronic acid to help extend smooth, straight hair after a Brazilian or keratin treatment.

This kit is designed for at-home upkeep after professional straightening. The Keraliss Complex blends plant-derived keratin and hyaluronic acid to hydrate, reinforce the hair fiber and reduce frizz while remaining sulfate-free and vegan. Regular use aims to keep lengths more disciplined and the salon effect visible between touch-up treatments.

How does this kit help maintain straightened hair?

The trio works together to cleanse gently, seal and replenish moisture without stripping the treated structure. Ingredients target the cuticle to minimize humidity-induced swelling and preserve the smoothing effects of your salon service.

• Shampoo: sulfate-free cleansing that protects the treatment.
• Conditioner: detangles and smooths cuticles for easier styling.
• Mask: deeper conditioning to restore resilience and softness.

Can it really extend straightening results up to 18 weeks?

The formula was developed to help prolong the visible straight, smooth look beyond the typical span, depending on hair type and care routine. While individual outcomes vary, consistent use as directed supports longer-lasting discipline and reduced frizz.

• Use every wash to maintain the treated surface.
• Avoid harsh sulfates and salt that can shorten results.
• Complement with heat protection and limited high-heat styling.

What makes the Keraliss Complex and hyaluronic acid important?

Vegetal keratin helps replenish structural proteins in the hair, while hyaluronic acid binds moisture to improve elasticity and softness. Together they focus on targeted hydration and strengthening without weighing hair down.

• Vegetal keratin: supports fiber integrity and reduces breakage.
• Hyaluronic acid: attracts and retains hydration for suppleness.
• Sulfate-free base: preserves smoothing treatments and color.

Is this safe for colored or sensitized hair?

Yes — the formula is formulated without sulfates, added gluten or salt, and is vegan and cruelty-free, making it gentle on color-treated and chemically processed hair. It’s intended for ongoing maintenance rather than as a corrective professional treatment.

• Free from sulfates and added salt to protect treated hair.
• Vegan and cruelty-free for ethical consideration.
• Suitable for daily or regular use after straightening services.

Who is this for: The KATIVA Brazilian Post Straightening Treatment Kit is aimed at people who have had a Brazilian or keratin straightening service and want a reliable at-home routine to maintain smooth, frizz-controlled hair. It’s suitable for those with color-treated, sensitized or naturally textured hair who prefer sulfate-free, vegan formulas to extend salon results and keep hair hydrated and manageable between professional treatments.
