NK Professional Care Keratin Hair Straightening Treatment 450ml — 2-Step Salon Formula for Frizz Control & Smoother Hair

NK Professional Care Keratin Hair Straightening Treatment is a two-step professional salon formula that reconstructs and smooths all hair types in about 40 minutes for soft, manageable, straightened results.

This concentrated keratin system is designed for professional use to reduce frizz, strengthen strands, and deliver a sleek finish without long wait times. The kit combines a nutrient-rich pre-treatment with a keratin-rich treatment cream that works together to open the cuticle, infuse protein and moisture, then seal the shaft for a visibly smoother texture. Optimized for coarse, thick, curly, or frizzy hair, the 450ml size balances salon capacity with ease of handling during service.

How does the two-step method work to straighten hair?

The two-step process first prepares the hair by nourishing and gently opening the cuticle, then the keratin treatment penetrates and reconstructs the fiber. The system’s timing and sequence are designed for predictable salon results in a single appointment, avoiding multi-day wait protocols. Results depend on correct application and heat styling as directed by professional stylists.

• Step 1: Pre-treatment cream nourishes and dilates the capillary cuticle for better product absorption.
• Step 2: Keratin treatment cream is applied and developed for about 40 minutes to smooth and reconstruct.
• Follow-up: Rinse and neutralize as recommended, then style for a long-lasting sleek finish.

What key ingredients deliver conditioning and protection?

The formula blends keratin with conditioning actives like Vitamin E, Panthenol, Aloe Vera, and Betaine Coconut to support hair integrity while smoothing. These components work together to hydrate, reduce breakage, and improve manageability without stripping natural texture. The treatment is crafted to replenish proteins and lock in moisture during the straightening process.

• Keratin: rebuilds and smooths the hair fiber for reduced frizz and improved shine.
• Vitamin E and Panthenol: antioxidant and moisture-retaining agents that help protect strands.
• Aloe Vera and Betaine Coconut: calming, hydrating ingredients that help maintain softness.

How long do results last and what aftercare helps maintain them?

With proper professional application and recommended aftercare, clients can expect smoother, more manageable hair for weeks, depending on hair type and maintenance routine. Use sulfate-free shampoos and avoid mineral-heavy water when possible to extend results. Regular moisturizing treatments and limited heat exposure will help preserve the keratin benefits.

• Use gentle, sulfate-free cleansers to protect the keratin layer.
• Avoid frequent high-heat styling to maintain protein integrity.
• Recommend periodic conditioning masks to sustain softness and shine.
