SHISEIDO Crystallizing Straight H Straightener 400g + Neutralizer Cream 400g
SHISEIDO Crystallizing Straight H Straightener is an innovative thermal straightening system developed by Shiseido Professional, specifically formulated for resilient, healthy, naturally curly, or resistant hair. This two-step system combines the first agent (H 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 an unprecedented level of smoothness, shine, and lightweight movement.
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 formula is enriched with Hydroxyproline and other hair-protecting ingredients that help inhibit thermal denaturation damage during heat styling. The product features an elegant green-floral fragrance that effectively masks unpleasant perm odors, making the treatment process more pleasant.
