KERATIN RESEARCH Keratin Hair Treatment Smoothing & Frizz Control — 4 oz Professional Formula, 4–6 Month Results

KERATIN RESEARCH Brazilian Keratin is a professional-grade 120ml (4 oz) hair straightening and smoothing treatment that reduces frizz and gives shiny, smooth hair for 4–6 months when applied as directed.

Engineered for at-home or salon use, this concentrated keratin formula blends hydrolyzed keratin proteins with argan oil and collagen amino acids to strengthen hair, smooth the cuticle, and improve manageability. The product targets frizz and surface damage without relying on temporary masking agents, delivering longer-lasting alignment of hair fibers when paired with the recommended heat sealing step. Each 120ml bottle treats most hair lengths; very long or very thick hair may need two bottles or the 10 oz version.

How long will the smoothing effect last on my hair?

When properly applied and heat-sealed, results from KERATIN RESEARCH usually persist for 4–6 months. Longevity depends on hair porosity, washing frequency, and the use of sulfate-free shampoos. Avoiding heavy chlorine and minimizing frequent harsh shampoos helps preserve the treatment.

• Typical duration: 4–6 months
• Best maintenance: sulfate-free products, limited chlorine exposure
• Hair factors: porosity and previous chemical services affect longevity

Will this formula work on all hair types and levels of damage?

Yes — the formula is designed to smooth, strengthen, and repair across a range of hair types, from fine to coarse and from chemically processed to naturally textured. It supplies hydrolyzed keratin to reinforce weakened strands, while argan oil adds shine and manageability. Very coarse or extremely long hair may require additional product for full coverage.

• Suitable for fine, medium, coarse, and chemically treated hair
• Reinforces damaged cuticles with keratin proteins
• Argan oil and collagen amino acids add shine and resilience

How do I apply the KERATIN RESEARCH treatment safely at home?

Application follows a few key steps: shampoo with clarifying product, apply the keratin evenly, allow processing time, and seal with heat (flat iron) as instructed. Work in sections and use consistent heat to lock the formula into the hair shaft for optimal smoothing results. Professional support is available if you have application questions or unique hair conditions.

• Prep: clarify hair before application
• Apply evenly in sections and follow processing time
• Seal with a flat iron at recommended temperatures
• Seek support from responsive customer service if needed

What size should I choose and how much product is included?

This listing contains one 120ml (4 oz) bottle, designed to treat short to medium lengths or provide a touch-up for longer hair. For very long, thick, or coarse hair, purchase two 120ml bottles or select the 10 oz option for complete coverage. The concentrated formula means controlled, section-based application maximizes each bottle.

• Included: 120ml (4 oz) bottle
• Recommendation: 2 bottles or 10 oz for very long/thick hair
• Concentrated dose: section-based application conserves product

Who is this for?

It appeals to DIY users comfortable following heat-sealing instructions and to professionals looking for a reliable keratin blend that combines proteins, argan oil, and collagen amino acids for resilient, manageable hair.
