The Core of Kéralis noir: Hair Foundation Care
Kéralis noir is built on the philosophy of “hair foundation care.” At its heart lies a proprietary blend of repair ingredients, including highly-regarded low-molecular “active keratin” and professional-grade hematic. These ingredients are meticulously selected to address not just the superficial appearance but to reconstruct hair from its innermost core. The line is formulated for those whose hair has become unmanageable due to accumulated damage from continuous coloring, perms, or the natural effects of aging.
Multi-Stage Keratin Approach
The products utilize a sophisticated combination of three to four types of keratin to provide comprehensive repair from the inside out:
-
Low-Molecular “Active Keratin”: This French-made keratin, with a molecular weight of 300-700Da, is designed to deeply penetrate and adhere to the hair’s internal structure. Unlike conventional hydrolyzed keratins, its stable, hair-like structure allows for effective internal repair. This is crucial because molecules larger than approximately 500Da typically struggle to pass through biological barriers like the stratum corneum or cuticles.

-
Medium-Molecular Keratin: With a molecular weight of 1,000-10,000Da, this keratin (from wool) works to repair both the internal and surface layers of the hair.
-
High-Molecular “Raw Keratin”: Found exclusively in the treatment, this keratin (from wool) has a molecular weight of 30,000-60,000Da. It forms a gentle protective layer on the hair surface, imparting firmness, body, and shine.


Professional-Grade Repair Components
Beyond keratin, Kéralis noir incorporates other powerful ingredients:
-
Hematic: A well-known hair repair ingredient in salon work, hematic helps repair hair and remove residual alkali from chemical treatments. By binding with proteins, it stabilizes and enhances the hair’s internal keratin, providing moisture and a smooth texture.
-
Tostear®: This thio-succinic acid derivative corrects distorted internal hair structures, addressing frizz and unevenness.
-
Pellicer®: Known for its rapid penetration, Pellicer forms a repair film within the hair in just one minute.
-
Lipidure®: Offering approximately twice the moisturizing power of hyaluronic acid, Lipidure ensures sustained hydration and improves surface texture.
-
γ-Docosalactone: A heat-activated ingredient that helps straighten and improve frizzy or unruly hair.
Shampoo: Gentle Cleansing, Building the Foundation
The ISSHI Kéralis noir Shampoo Smoothing Repair Moist is formulated with gentle, low-irritation cleansing agents, including taurine, amino acid, betaine, and imino-type amino acids. This luxurious blend cleanses while allowing low-molecular “active keratin” and other repair components to penetrate deeply, rebuilding the hair’s foundation. It doesn’t just clean; it prepares the hair to effectively receive further care.


Hair Treatment: Layered Repair for a Polished Finish
The ISSHI Kéralis noir Hair Treatment Smoothing Repair Moist complements the shampoo by offering a “layered repair” approach. It combines low-molecular “active keratin” and professional repair components with high-molecular “raw keratin” to protect the hair’s exterior. This targeted action addresses both internal and external damage, smoothing frizz and leaving hair light, lustrous, and beautifully manageable.


The unique brown or moss green color of ISSHI Kéralis noir products is a testament to the high concentration of hematic, a key repair ingredient, offering a visual cue to its powerful formulation. The fragrance, “Noir Clean,” is a sophisticated blend selected by a perfumer from Grasse, France, evolving from a clean citrus to a gentle musk.
User Reactions: “Salon Hair in Everyday Life”
Early users of ISSHI Kéralis noir have expressed significant satisfaction. One user commented, “As expected from ISSHI! The moisture retention, the smoothness of my fingers through my hair, the shine on the surface, and the fullness like it’s packed with hydration. My hair feels so healthy that there’s no static when I run my fingers through it. I feel that this will only get stronger with continued use!” This sentiment of experiencing “salon-level beautiful hair in everyday life” echoes throughout the feedback, highlighting the product’s immediate and tangible effects.
