SHISEIDO Crystallizing Straight H Straightener 400g (Resistant to natural hair)

SHISEIDO Crystallizing Straight H Straightener 400g

SHISEIDO Crystallizing Straight H Straightener is the first-step straightening cream in the innovative thermal straightening system developed by Shiseido Professional, specifically formulated for resilient, healthy, naturally curly, or resistant hair. This first agent, used in conjunction with the second-step neutralizer and a flat iron, effectively straightens 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.

Key Features:

• Designed for Resistant & Healthy Hair: The H series is specifically developed for strong, healthy, naturally curly, or difficult-to-soften resistant hair types, delivering superior 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.
• Effective Repair & Heat Protection: Enriched with Hydroxyproline and other protective ingredients that safeguard hair during the straightening process, reducing damage from heat and chemical treatments.
• 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.
