SHISEIDO Crystallizing Straight N Straightener 400g + Neutralizer Cream 400g
SHISEIDO Crystallizing Straight N Straightener is an innovative thermal straightening system developed by Shiseido Professional, specifically formulated for natural to lightly sensitized hair that has undergone bleaching or chemical treatments. This two-step system combines the first agent (N Straightener) with the second agent (Neutralizer Cream), used in conjunction with a flat iron to effectively straighten stubborn natural curls, waves, or frizzy hair while minimizing damage to the hair fiber, delivering a smooth, glossy, and lightweight finish.
Its unique Dual Performance System efficiently straightens while deeply repairing hair, improving texture and softness, leaving hair with a natural luster that is easy to manage. The first agent is formulated with Hydroxyproline to inhibit thermal denaturation damage, while the second-agent cream neutralizer contains Lipidure® to repair the damaged CMC (Cell Membrane Complex) structure caused by chemical treatments. The system features an elegant green-floral fragrance that effectively masks unpleasant perm odors, making the treatment process more pleasant.
Key Features:
Designed for Natural to Sensitized Hair: The N series is specifically developed for normal, lightly damaged, bleached (once), or chemically treated hair, delivering gentle yet effective straightening results.
Innovative Thermal Straightening System: Utilizes a cold two-bath method combined with a high-temperature flat iron (recommended below 180°C) to effectively restructure the hair fiber for long-lasting results.
Dual Repair Efficacy: The first agent contains Hydroxyproline to inhibit heat damage, while the second-agent cream neutralizer features Lipidure® to repair CMC, creating a soft and smooth finish.
Creates Sleek, Glossy Texture: After treatment, hair becomes straight, smooth, and radiant with a lightweight, bouncy feel — no more frizz.
Odor Control: Specially formulated with an elegant floral fragrance that effectively minimizes unpleasant chemical odors during application.
