Shiseido 1EX Straightener for Very Resistant to Resistant Hair 400g

Shiseido Crystallizing Straight 1EX Straightener for Very Resistant to Resistant Hair is a professional salon straightening cream specifically formulated for very resistant to resistant hair types. As the first step in the renowned Shiseido Crystallizing Straight System, this advanced Japanese straightening treatment restructures the hair's internal bonds to create permanently smooth, sleek and manageable results while maintaining exceptional shine and softness.

Developed using Shiseido's innovative hair science technology, the 1EX Straightener is designed to effectively straighten coarse, thick and highly resistant hair that requires greater straightening power. The professional-strength formula penetrates deeply into the hair fibre, allowing stylists to reshape the hair's natural structure while helping maintain its condition, elasticity and healthy appearance.

The smooth cream consistency provides excellent control during application, ensuring even distribution from roots to ends for consistent straightening results. When paired with the Shiseido Crystallizing Straight Neutralizer, the system permanently locks the hair into its new straight configuration, leaving it silky, frizz-free and noticeably easier to manage.

Ideal for clients with naturally coarse, dense or difficult-to-straighten hair, the 1EX Straightener delivers long-lasting straightening while reducing unwanted volume, improving manageability and enhancing natural shine. Hair is left feeling soft, smooth and polished with a sleek finish that lasts until new hair growth appears.

Trusted by professional salons around the world, the Shiseido Crystallizing Straight System is recognised for its premium Japanese technology, predictable performance and beautiful straightening results across a variety of hair types.
