KATIVA Brazilian Keratin Treatment Kit — Formaldehyde-Free, with Hyaluronic Acid for Up to 12 Weeks Frizz Control

KATIVA Brazilian Keratin Treatment Kit is a formaldehyde-free at-home straightening system that smooths, hydrates and controls frizz for up to 12 weeks when used as directed.

Designed for people who want salon-style smoothing without formaldehyde, this complete kit pairs a professional straightening mask with a post-treatment shampoo and conditioner enriched with organic argan oil, shea butter and plant-based keratin. Hyaluronic acid adds moisture and flexibility to strands while the vegan, sulfate- and gluten-free formula aims to respect hair and scalp. The kit is suitable for curly, wavy and frizzy hair types looking to reduce volume and enhance shine.

How does this kit smooth my hair at home?

The straightening mask contains vegetal keratin and conditioning agents that help align and seal the hair fiber when combined with heat styling. Used with the included post-treatment shampoo and conditioner, it reinforces the smoothing effect and helps maintain a straighter appearance between salon visits.

• Vegetal keratin supports hair fiber structure and reduces visible damage.
• Hyaluronic acid deeply hydrates strands for improved elasticity.
• Follow kit instructions and heat application for optimal alignment.
• Post-treatment shampoo removes residue and extends smoothness.

Is this safe for chemically treated or colored hair?

The formula is formaldehyde-free and made without added salts or sulfates, which makes it gentler than some traditional keratin systems. However, prior chemical treatments can affect results, so perform a strand test or consult a stylist if your hair has recent color, bleach, or chemical relaxers.

• Vegan and cruelty-free formulation reduces harsh additives.
• No added salt, sulfates, or gluten to limit stripping of color.
• Strand test recommended for heavily processed hair.
• Use the included shampoo and conditioner for best maintenance.

How long will the straightened effect last and how do I maintain it?

With correct application and the recommended aftercare, the smoothing effect can last up to 12 weeks, though results vary by hair porosity and lifestyle. Regular use of the kit’s shampoo and conditioner plus heat-protective styling will help sustain the look and reduce frizz in humid conditions.

• Expected duration: up to 12 weeks with proper care and routine.
• Use the included shampoo and conditioner to protect the treatment.
• Limit frequent washing and use gentle, sulfate-free products afterwards.
• Protect hair from excess humidity and frequent high heat styling.

What visible improvements can I expect after treatment?

After using the mask and post-treatment system, hair typically appears smoother, softer and shinier. Frizz and excess volume are reduced, while hyaluronic acid helps retain moisture so strands feel more manageable and less prone to breakage.

• Noticeably reduced frizz and more controlled volume.
• Improved softness and enhanced shine from argan oil and shea butter.
• Hydration and flexibility from hyaluronic acid for less brittleness.
• Stronger-feeling hair due to plant-based keratin support.

Who is this for: This kit is ideal for anyone with curly, wavy or frizzy hair who wants a longer-lasting, at-home smoothing solution without formaldehyde or harsh sulfates. It suits people seeking improved manageability, reduced frizz and added shine, including those with color-treated hair who follow the advised strand testing and aftercare routine.
