Kativa 12-Week Brazilian Straightening Kit with Argan & Keratin
A solid at-home option for reducing frizz and achieving long-lasting smoothness, especially if you value conditioning ingredients like argan oil and keratin. Best for people comfortable with multi-step heat-activated treatments and willing to follow safety and timing guidelines for optimal results.
Kativa Brazilian Straightening Kit: 12 Weeks at Home — Professional-Style Results
Overview
Kativa’s Brazilian Straightening Kit promises a professional-style smoothing treatment you can do at home, with results that can last up to 12 weeks. The formula pairs glyoxylic straightening chemistry with a cocktail of care ingredients — organic argan oil, shea butter, vegetal keratin and amino acids — designed to soften fiber, reduce frizz, and add shine while creating a thermo-reactive memory that activates with heat.
How the System Works
The treatment is a multi-step process that uses a pre-treatment shampoo to cleanse, a conditioning mask containing the straightening active, and a final wash-and-condition to set the effect. Heat from blow drying and flat-ironing is the trigger that locks the smoothing action into the hair cuticle. The brand emphasizes that the straightening is activated and reinforced by heat, which is why precise drying and ironing steps matter.
What’s Included in the Kit
The mask contains the glyoxylic acid-based smoothing agent plus moisturizing and protein-based ingredients to reduce stiffness and dryness that some other straighteners can cause.
Key Ingredients and Their Roles
Understanding these ingredients helps explain why the kit aims to both straighten and condition rather than simply forcing the hair into a stiff shape.
Step-by-Step Application (High-Level Summary)
Note: This is a descriptive overview of the process; always follow the kit leaflet and safety warnings.
Careful timing, full drying, and consistent flat-iron passes are what produce the lasting smoothness; skipping drying or rushing the ironing can reduce longevity.
Safety & Practical Tips
Safety and technique have a direct impact on both results and hair health — give yourself time and, if possible, an assistant for back sections.
Expected Results and Longevity
Post-treatment you can expect significantly reduced frizz, smoother texture, and easier styling. Results vary by hair porosity, curl pattern, and how strictly the instructions are followed. Most users report full benefits for around 8–12 weeks; touch-ups or reapplication are typically needed after the effect fades.
Aftercare: Maintain the Finish
Aftercare will extend the duration of visible smoothness and help hair retain moisture and shine.
Who Should Use It (and Who Shouldn’t)
Best suited for people with wavy, frizzy, or curly hair who want a long-lasting smoothing treatment at home. Those with brittle, severely damaged, or scalp-sensitive hair should consult a professional or perform a strand test first. Pregnant people and those with respiratory sensitivity should take extra precautions due to fumes and consider deferring treatment.
Quick Comparison Table: At-Home Kit vs. Salon Keratin Treatment
| Feature | Kativa At-Home Kit | Typical Salon Keratin |
|---|---|---|
| Cost per treatment | Lower (affordable kit) | Higher (stylist time + product) |
| Control over application | User-dependent | Professional application |
| Fumes & ventilation | Present (heat activation) | Present (often similar chemistry) |
| Longevity | Up to 12 weeks | Often 2–6 months depending on treatment |
| Conditioning ingredients | Argan, shea, keratin | Varies; often higher concentrations |
This comparison shows the at-home kit is budget-friendly and effective, but technique matters more when you do it yourself.
Realistic Expectations
The kit performs best when users follow steps precisely: thorough drying, careful ironing, and correct timing. For many people the result is much smoother, shinier, and more manageable hair, but it may not produce a perfectly “bone straight” look for the curliest textures. Expect improved manageability and reduced styling time rather than a permanent change.
Final Notes
Kativa’s formula walks a practical line between conditioning and chemical smoothing, aiming to reduce frizz while adding shine and strength. If you want a cost-effective, at-home pathway to smoother hair and are willing to invest a couple hours into a careful application, this kit is a strong candidate. Treat the first application as a practice run: read instructions, watch demos, and protect yourself with adequate ventilation and gloves.
FAQs
Most users report results lasting between 8 and 12 weeks depending on hair type, porosity and how well the application steps are followed. Fine or low-porosity hair may lose the effect sooner; very coarse hair may require more passes during ironing for longer hold.
Many people with dyed hair use the kit successfully, but the mask can slightly alter color or lighten tones. If you color your hair, plan to either color after the straightening or perform a strand test first. Deeply damaged colored hair should be assessed before treatment.
You can get strong results at home if you follow the directions closely, watch tutorials, and have the right tools (good flat iron and dryer). However, salon professionals will often achieve more consistent results, especially for very thick or long hair.
The fumes during heat activation can be strong. Minimize exposure by working in a well-ventilated area, opening windows, using a fan, wearing a mask if you’re sensitive, and avoiding inhaling directly during ironing. Gloves are recommended to protect skin.
Yes — trimming after the treatment is fine and often recommended if small missed ends appear. Coloring can be done, but many stylists suggest waiting a short time or doing color after smoothing to avoid unexpected shifts in tone.
Use sulfate-free shampoos, avoid overwashing, apply nourishing conditioners and masks regularly, and use heat protectant sprays for future styling. Gentle handling and limited exposure to harsh chemicals will help the results last longer.

Quick notes from someone with coarse hair: it cut my morning styling time in half. The product’s conditioning ingredients (argan oil, shea butter) actually help, but you must follow the neutralizing rinse and ironing steps precisely.
Also — use heat protectant before the flatiron even though the kit has conditioning agents. Safety first.
Great practical tip, Noah. The kit contains conditioning agents but a separate heat protectant is a smart extra layer of protection.
Agreed on the heat protectant. I used a ceramic iron at lower temps and it still smoothed nicely.
Neutral on this — results were okay for me but I didn’t love the smell during processing. Also took a full afternoon to do my shoulder-length hair. Not sure I’d do it monthly, maybe every 3 months.
