Description

Maintain your Brazilian straightening results for longer with the Kativa Brazilian Post Straightening Treatment Kit, a complete 3-step routine designed for daily use at home. This set includes a Shampoo, Conditioner and Intensive Mask formulated to help prolong the effect of your straightening treatment for up to 18 weeks when used regularly as directed. It is ideal after Brazilian or keratin straightening and for hair that needs long-lasting smoothness, frizz control and hydration. Powered by the exclusive Keraliss Complex, the formulas combine vegetal (plant-based) keratin and hyaluronic acid to work inside the hair fiber. They help deliver the right dose of moisture and nutrients to restore, strengthen and smooth the hair, so it looks healthier and feels softer with each use. The Sulfate-Free Shampoo gently cleanses without stripping or disrupting the straightened structure. It removes impurities and build-up while helping preserve the smoothing effect. The Detangling Conditioner instantly softens, helps detangle and makes hair easier to comb. Lengths feel more supple, light and silky without being weighed down. The Intensive Repair Mask provides deep care for dry, damaged or heat-stressed hair. It helps nourish, repair the look of damage and restore natural shine, leaving hair smoother and more disciplined. This routine is suitable for a wide range of hair types and textures: Straightened or Brazilian straightening: helps maintain a smoother, shinier look for longer. Wavy or curly hair: helps control volume, tame frizz and smooth the fiber. Dry, damaged or sensitized hair: delivers hydration, softness and a more uniform appearance. Colored or bleached hair: sulfate-free formula suitable for color care when used as directed. Vegan, cruelty free and free from sulfates, added salt and gluten, this kit offers a gentle yet effective way to care for straightened hair and keep it looking smooth, shiny and easy to style from home. Results may vary depending on hair type, previous treatments and maintenance routine.
