SHISEIDO Crystallizing Straight Professional Hair Straightening Set (N1/H1) — 400 mL + Neutralizer 400 mL

Crystallizing Straight is SHISEIDO’s salon-trusted system for transforming wavy, frizzy, or coarse hair into sleek, straight strands with lasting hold. The creamy Straightener (choose N1 for normal/processed hair or H1 for healthy, resistant hair) reshapes the hair bonds, while the Neutralizer locks in the new straight structure. Results: smoother cuticles, mirror shine, and a natural, soft movement. Why you’ll love it Two strengths: N1 (normal/chemically treated) or H1 (thick/resistant). Cream texture spreads evenly; minimal dripping for clean application. Helps reduce puffiness and frizz; improves light reflection for glossy hair. Long-lasting straight look when followed with neutralizing and heat ironing. Professional-size bottles: Straightener 400 mL + Neutralizer 400 mL. How to use Cleanse hair (no conditioner). Towel dry and blow to ~80–85% dry. Section hair. Apply Straightener 1–2 cm from scalp in thin layers. Guide time: N1 (10–20 min), H1 (25–35 min). Strand-test every 5–10 min. Rinse thoroughly. Blow-dry 100% and flat-iron in thin slices (170–210°C depending on hair health). Let hair cool 3–5 min. Apply Neutralizer evenly; leave 10 min. Rinse, apply leave-in, blow-dry, and finish.
