KATIVA Brazilian Keratin Treatment At-Home Kit — Formaldehyde-Free with Hyaluronic Acid Hydration

KATIVA Brazilian Keratin Treatment Kit is a formaldehyde-free at-home straightening system that smooths and reduces frizz for up to 12 weeks while delivering hydration with hyaluronic acid and vegetal keratin.

This professional-grade bundle combines a straightening mask, post-treatment shampoo and conditioner to create a salon-style smoothing ritual at home. Formulated without formaldehyde, sulfates, added salt or gluten, the trio uses organic argan oil, shea butter, vegetal keratin and hyaluronic acid to hydrate, support the hair fiber and tame volume and humidity-induced frizz. Use as directed for best results and follow the included aftercare to extend the straightened appearance.

How does the kit smooth hair and control frizz?

The main smoothing mask works by coating and reorganizing the hair surface, reducing curl pattern appearance and helping strands lie flatter. Hyaluronic acid attracts and retains moisture so hair remains flexible; vegetal keratin reinforces weakened areas of the fiber for improved texture. Together with the post-treatment shampoo and conditioner, the system helps maintain a disciplined look between salon visits.

• Straightening mask reconfigures surface for smoother fall
• Hyaluronic acid hydrates and prevents stiffness
• Vegetal keratin supports damaged areas and reduces breakage look
• Aftercare shampoo and conditioner protect against humidity-driven frizz

What results can I expect and how long will they last?

Results vary by hair type, porosity and styling routine, but many users observe a noticeably straighter, shinier appearance that can last up to 12 weeks with careful aftercare. Maintaining sulfate-free cleansing, limited heat and gentle detangling helps preserve the effect. Touch-up frequency depends on new hair growth and how often you wash and heat-style your hair.

• Visible smoothing and reduced volume after first treatment
• Shine and softness that improve with the conditioning trio
• Up to 12 weeks of reduced frizz when following maintenance guidelines
• Reapplication recommended as new growth appears or texture returns

Is this safe for my hair type and free from harsh chemicals?

The formula is designed for a wide range of hair textures — curly, wavy and frizzy — and is labeled formaldehyde-free, vegan and cruelty-free. It also avoids added salt, sulfates and gluten, reducing potential irritants for many users. Always perform a patch and strand test and read package instructions to confirm compatibility and avoid unexpected results.

• Suitable for curly, wavy and frizz-prone hair
• Formaldehyde-free, vegan and cruelty-free formulation
• No added salt, sulfates or gluten in the included products
• Patch and strand test recommended before full application

How should I use the kit for best at-home results?

Start with clean, dry hair and follow the included step-by-step directions for application, processing time and heat sealing. Rinse and use the post-treatment shampoo and conditioner according to the recommended schedule to lock in smoothness and protect the hair fiber. Limit clarifying or sulfate shampoos and avoid heavy exposure to humidity immediately after treatment to maximize longevity.

• Apply mask to dry hair following package timing and heat steps
• Rinse thoroughly and use the provided shampoo and conditioner afterward
• Use sulfate-free products and gentle styling to prolong results
• Perform maintenance washes and occasional touch-ups as needed
