Product details
KERATIN RESEARCH Brazilian Keratin Hair Straightening Complex is a two-step professional-grade treatment (120ml treatment + 120ml clarifying shampoo) designed to smooth, strengthen, and visibly straighten hair for long-lasting blowout results.
This fast, salon-quality system combines keratin proteins, argan oil, and collagen amino acids to restore elasticity, reduce frizz, and make hair easier to style. The kit is formulated for straightforward at-home or salon application and aims to deliver straightening results that last months while improving hair manageability and shine. It’s suitable for a wide range of hair types and built for people who want a polished, low-maintenance look without frequent salon visits.
How does this treatment create long-lasting straightness?
The formula works by depositing keratin proteins and conditioning agents along the hair shaft, helping to reorganize texture and reduce visible frizz. When combined with heat from a flat iron during the finishing step, the treatment locks a smoother surface in place for extended periods. While individual results depend on hair porosity and maintenance, many users report 4–6 months of improved straightness and reduced styling time.
- Dual-step system: clarifying shampoo plus keratin solution
- Keratin proteins rebuild structure and reduce frizz
- Argan oil adds shine and improves slip for easier flat-ironing
- Heat-activated sealing for multi-month results
What is included and how simple is the application?
The kit contains one 120ml bottle of keratin treatment and one 120ml clarifying shampoo to prepare hair for optimal absorption. The process is straightforward: clarify, apply treatment, process per directions, and seal with a flat iron; clear instructions are provided and customer support is available for questions. This makes the system practical for home use or for busy salon schedules.
- 120ml clarifying shampoo to remove buildup and open cuticle
- 120ml keratin treatment for smoothing and conditioning
- Stepwise application for safe, repeatable results
- Responsive support to help troubleshoot application steps
Will it work on my hair type and how gentle is it?
Designed for all hair types, the formulation balances smoothing power with conditioning to preserve hair health and elasticity. It does not promise medical or permanent changes; rather it improves manageability, reduces frizz, and enhances shine while replenishing proteins and lipids. People with highly porous or chemically treated hair should follow the included directions and consider a professional consultation if unsure.
- Suitable for straight, wavy, curly, and chemically-treated hair
- Conditioning blend minimizes dryness during straightening
- Improves comb-through and reduces daily styling time
- Follow instructions for best, safest outcomes
How should I maintain results after treatment?
Maintaining straightness means using gentle, sulfate-free shampoos, limiting excessive washing, and protecting hair from high heat and chlorine. Regular use of nourishing masks and leave-ins that support keratin and argan oil benefits will extend the smooth effect. Periodic touch-ups with the same system or professional refinements keep results consistent across seasons.
- Use sulfate-free, gentle cleansers to preserve the keratin layer
- Limit washing to preserve treatment longevity
- Use heat protectant when styling with tools
- Schedule touch-ups every 4–6 months as needed
Who this is for: KERATIN RESEARCH Brazilian Keratin Hair Straightening Complex is for anyone seeking a reliable, time-saving way to achieve salon-style smoothness at home or in a professional setting. It suits people who want reduced frizz, more manageable hair, and longer-lasting straight results without daily thermal styling. If you prefer professional finishes, want to restore softness after chemical processes, or simply desire fewer morning styling steps, this two-step kit offers a concentrated, user-friendly solution.
