Shiseido Crystallizing
Shiseido Professional's Crystallizing line is a salon-grade hair-straightening (rebonding) system sold as matched solution sets - labeled N, H, H1, EX, and PC for different hair textures and treatment histories - alongside a Cool Designing Cream for post-straightening styling and hold. 15 items are currently in stock. Because the right solution strength depends on hair thickness, resistance, and whether it's been colored, these are best chosen with a stylist rather than picked at random.

SHISEIDO Professional Crystallizing: how the straightening system is organized
Crystallizing is Shiseido Professional's hair-straightening (rebonding) system, sold as solution sets rather than a single all-purpose product. This page rounds up the 15 in-stock items from that line so you can see how the solutions, straighteners, and finishing cream fit together.
What the Crystallizing system does
Crystallizing is built for chemical hair straightening in a salon setting: a first solution softens the hair's internal bonds so it can be reshaped straight, followed by a second step that resets and locks the new shape in place.
Reading the solution letters - N, H, H1, EX, PC
The line ships in several labeled strengths - Straight N, H, H1, EX, and PC - matched to different hair conditions, from fine or normal hair up to coarse, resistant, or previously colored/treated hair. A stylist typically picks the strength based on how the hair reacts to a strand test, since using too strong a solution on fine or damaged hair risks over-processing.
N1 and EX Straightener (400ml)
The N1 Straightener and EX Straightener bottles are the liquid straightening solutions in 400ml sizes, used during the reshaping step of the service for normal and more resistant hair respectively.
Crystallizing Straight Magic Solution Cul
This is a supporting step within the same Crystallizing system, used alongside the main straightening solutions as part of a full-service application rather than sold as a standalone straightener.
Crystallizing Cool Designing Cream (400g)
Once hair is straightened, the Cool Designing Cream is a finishing product used to style and hold the result, rather than a treatment step - it's applied after the chemical process is complete.
Who these products are for
Because Crystallizing is a professional chemical system, it's aimed at salons and trained stylists rather than a casual at-home swap for a flat iron. If you're not a professional, treat this page as a reference for what your stylist may be using rather than a shopping list to self-apply.
How to use this page
The product grid below lists all 15 in-stock Crystallizing items by name. Check each product page for exact solution type and volume before ordering, since the letter suffix is the main thing that distinguishes one bottle from another.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What is Shiseido's Crystallizing line used for?
It's a professional hair-straightening (rebonding) system: a softening solution followed by a resetting step that leaves hair straight, plus a finishing cream for styling afterward.
What's the difference between the N, H, H1, EX, and PC solutions?
The letters mark different solution strengths matched to hair condition - roughly normal hair through coarser, more resistant, or previously colored hair. A stylist usually confirms the right strength with a strand test before applying.
Is the Cool Designing Cream part of the straightening process?
No - it's a finishing product applied after straightening to style and hold the result, not one of the chemical solutions used during the treatment itself.
Can I use Crystallizing products at home instead of at a salon?
These are professional chemical formulas built for trained stylists, not a direct swap for a flat iron. If you're not a professional, it's worth using this as a reference for what your salon may use rather than a self-application kit.
