Shiseido 1N Straightener for Natural to Sensitized Hair 400g

Shiseido Crystallizing Straight 1N Straightener for Natural to Sensitised Hair is a professional salon straightening cream specially formulated for natural to sensitised hair. As the first step in the renowned Shiseido Crystallizing Straight System, this advanced Japanese straightening treatment gently restructures the hair's internal bonds to create permanently smooth, sleek and manageable results while helping maintain the hair's strength, softness and natural shine.

Developed with Shiseido's innovative hair science technology, the 1N Straightener is designed to effectively straighten hair that is natural or lightly sensitised from previous colour or chemical services. The carefully balanced formula provides effective straightening performance while helping protect the integrity of the hair fibre, making it an excellent choice for clients who require a gentler approach without compromising on results.

The rich cream consistency ensures smooth, controlled application and even distribution from roots to ends, allowing for consistent processing and predictable straightening results. When used in conjunction with the Shiseido Crystallizing Straight Neutralizer, the system permanently reforms the hair's internal structure, locking the hair into its new straight shape while reducing frizz and improving manageability.

Ideal for clients with natural hair or hair that has been lightly sensitised, the 1N Straightener helps reduce unwanted volume, smooth the cuticle and create beautifully straight hair with natural movement and a healthy-looking finish. Hair is left silky, glossy and easier to style, delivering long-lasting results that remain until new hair growth appears.

Trusted by professional salons worldwide, the Shiseido Crystallizing Straight System is renowned for its premium Japanese technology, predictable performance and exceptional straightening results across a wide range of hair types and conditions.
