KERATIN RESEARCH Brazilian Keratin Hair Treatment 240ml — Gold Label professional-strength, reduces frizz & adds long-lasting shin

KERATIN RESEARCH Gold Label Brazilian Keratin is a professional-strength 240ml straightening treatment formulated to reduce frizz, relax curl, and add long-lasting shine on all hair types, including coarse, curly, bleached, and ethnic textures.

This salon-grade formula blends keratin with a proprietary mix of argan, grape, avocado, and jojoba seed oils to penetrate and strengthen strands while standing up to repeated flat-iron passes. It’s made for home or professional use on diverse hair textures — from fine, color-treated hair to thick, coarse, or Afro-textured locks — and aims to tame frizz, improve manageability, and lock out humidity for extended styling results. Follow the included safety guidance: perform a patch test, use gloves, and work in a ventilated space to avoid irritation from fumes.

How quickly will I see smoother hair after using this treatment?

Most users notice reduced frizz and increased smoothness immediately after the full application and heat-sealing steps are completed. Final results develop as the hair cools and the treatment sets, with optimal outcome visible after styling.

• Immediate smoothing once treated and flat-ironed
• Full effect becomes apparent as hair cools and is rinsed/styled
• Results last longer when paired with sulfate-free maintenance products
• One 240ml bottle typically covers short-to-medium lengths for professional use

Is this safe for chemically treated, bleached, or color-treated hair?

Gold Label is formulated to work on color-treated and bleached hair, but treating fragile or heavily processed hair requires caution. A strand test and gradual application are recommended to evaluate tolerance and avoid overprocessing.

• Perform a strand or patch test before full application
• Use gentler timing/heat on very porous or damaged areas
• Follow with color-safe, sulfate-free shampoos to prolong results
• If unsure, consult a professional stylist for first application

How does the formula handle very coarse, thick, or natural-textured hair?

The enhanced Gold Label blend is engineered to penetrate denser hair structures and resist multiple flat-iron passes without breaking down. Oils like argan and jojoba help lock in moisture while keratin works to temporarily relax and align the hair cuticle for smoother texture.

• Designed for resilient performance on coarse and Afro-textured hair
• Oils protect against moisture loss during heat sealing
• Withstands repetitive iron passes to achieve straighter results
• Helps block humidity to reduce frizz in humid climates

What should I expect from the application process and safety precautions?

Application can take up to 150 minutes depending on hair length and stylist experience. Use gloves, ventilate the area, and avoid eye and respiratory irritation from fumes. Always start with a sample test and follow timing instructions specific to texture and condition.

• Allow up to 150 minutes for full application on longer hair
• Work in a well-ventilated space and wear protective gloves
• Perform a patch test to check sensitivity and processing time
• Rinse and flat-iron according to directions for best results

Who is this for: KERATIN RESEARCH Gold Label Brazilian Keratin is intended for anyone seeking professional-level smoothing and frizz control across a wide range of hair types — from fine, chemically-treated hair to thick, coarse, curly, or ethnic textures. It’s well-suited for salon professionals and experienced home stylists who follow safety steps and patch testing. If you have severely damaged hair or are unsure about timing and heat levels, consult a trained stylist before full application to tailor processing to your hair’s needs.
