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).
