About Kéralis

"Creating a world where beautiful hair, finished at the salon, is no longer special."

Kéralis, a professional-grade hair care brand, was born from this vision.

Kéralis is carefully designed to be easy for anyone to use and reproducible in daily life, based on professional insights, techniques, and quality standards that evolve daily from salon practices. What we aim for is not temporary care to cover up damage. Through a "hair foundation approach" based on cutting-edge salon knowledge, we aim to rebuild beauty from within the hair and restore its original shine.

Instead of letting damage be the end of your hair, Kéralis transforms it into the beginning of beauty.

—"Kéralis" combines "Kera" (=keratin), which accounts for about 90% of hair, and "lisse" (French for "smooth, straight"), meaning "Kera + lisse" – "rebuilding beauty from within the hair."—

**Reconstructs the hair's foundation with active keratin¹ × hematin⁶ × professional-grade repairing ingredients*²**

Gently cleanses damaged and wavy hair caused by coloring, perms, etc.,

and simultaneously repairs the inside and outside of the hair with luxurious professional-grade repairing ingredients*².

It leads to smooth, manageable hair with a light, silky texture and moisture.

**1. Intensive repair from inside to outside of hair with 3-4 types of keratin¹³⁴⁵**

① Low-molecular "active keratin"*¹ (Shampoo & Treatment)

French-made keratin that easily penetrates and adheres to the hair's interior

① Hydrolyzed keratin (wool) with a molecular weight of 300-700 Da* (0.9nm-1.3nm)

Normally, hydrolyzed keratin often has a weak bond with hair proteins, but the French-made keratin adopted by ISSHI Kéralis has a low molecular weight of 300-700 Da* (0.9nm-1.3nm) and is stable with a structure similar to hair.

Therefore, it has the characteristic of easily penetrating and adhering to hair, and is structured to repair from within the hair*¹.

*"500 Da rule (Bos & Meinardi, 2000)" = If the molecular weight exceeds approximately 500 Da (Dalton),

it cannot diffuse through biological barriers such as the stratum corneum and cuticle.

② Medium-molecular keratin*³*⁴

(Shampoo & Treatment)

Hydrolyzed keratin (wool) with a molecular weight of 1,000-10,000 Da. While repairing the inside of the hair, it also works to repair the surface of the hair.

③ High-molecular "raw keratin"*⁵ (Treatment only)

Keratin (wool) with a molecular weight of 30,000-60,000 Da.

Due to its high molecular weight, it gently protects the hair surface,

giving hair firmness, body, and shine.

2. Intensive repair for hair damaged by coloring and perms

"Hematin"*⁶, a repairing ingredient famous in salon work

"Hematin" is a hair repairing ingredient famous in salon work for hair repair and removal of residual alkaline agents. By binding with proteins, it becomes stable, and by binding with proteins (keratin) inside the hair, it exerts its effect, giving hair moisture and smooth finger-combing.

3. Further strengthens internal and external repair with professional-grade repairing ingredients*²

Shampoo: Gently cleanses and restores hair

While gently cleansing with mild cleansing ingredients, low-molecular "active keratin"*¹ and professional-grade repairing ingredients*⁶~*¹⁰ approach the inside of the hair to reconstruct its foundation. It not only removes dirt but also prepares the hair from its base to be in a "receptive state" for care.

1. Approaches the inside of hair with low-molecular repairing ingredients

The key to internal repair is "low molecular weight."

We use internal penetrating low-molecular repairing ingredients such as French low-molecular "active keratin"*¹.

By conditioning the deep parts of the hair while washing, we reconstruct the foundation for healthy and beautiful hair.

2. Luxurious and mild cleansing ingredients that gently wash damaged hair

The cleansing ingredients are a mix of taurine-based*¹¹, amino acid-based*¹², betaine-based*¹³, and repairing imino acid-based*¹⁴. This achieves ideal cleansing power and low irritation as a foundation for hair repair.

Ingredient System	Irritation	Cleansing Power	Features
Imino acid*¹⁴	Extremely low	High repairing power	"Washable beauty serum" Repairs hair as you wash Highest quality ingredient
Taurine-based*¹¹	Low	Moderate	"Ultimate golden balance" Effective ingredient for refreshing wash
Amino acid-based*¹²	Low	Gentle	"Moisture-protecting classic" Gently protects hair and scalp, leaves it moist and manageable
Betaine-based*¹³	Extremely low	Mild	"Ultimate skin-friendly" Gentle enough for babies

Hair Treatment: Finishes with selective "layered repair"

Protects hair from the outside with low-molecular "active keratin"*¹ and professional-grade repairing ingredients, plus high-molecular "raw" keratin*⁵.

Selectively targets damaged areas inside and outside the hair, and corrects damage and frizz with "layered repair."

Achieves high-quality shine and manageable beautiful hair while maintaining lightness.

Formulated with low-molecular "active keratin"*¹, hematin*⁶, and professional-grade repairing ingredients*² for accumulated damage.

The shampoo focuses on internal repair while washing to prepare the hair's foundation, and the treatment, in addition to these internal repairs, protects the outside with high-molecular "raw keratin"*⁵.

＜Actual comments from users＞

As expected, ISSHI!

The way moisture is retained, the smoothness to the touch, the luster on the hair surface, and the firmness and body as if filled with moisture inside. Because it's moisturized, there's no static electricity even when combing with fingers,

I felt that this product, including its cumulative effects, would exert even more power with continued use!

Light yet manageable

The light yet manageable texture without dryness was very pleasant.

The next morning, there was almost no dryness or frizz, which impressed me. This is exactly the product I was looking for.

Surprising results after just 1 use

I was suffering from spread and static electricity due to color damage, but I felt it was light yet manageable,

The finish made me want to keep using it. Above all, I was surprised by the feeling of effectiveness after just one use.

It was truly "salon-quality beautiful hair in everyday life"

Color damage, frizz and waves due to aging, dryness... I suffered from these every day, but this shampoo and treatment truly made my hair feel smooth and shiny, like after a salon visit.

I was surprised by the finish, which perfectly matched the concept of "salon-quality beautiful hair in everyday life."

Gentle washing experience

The shampoo's foam was comfortable, and I personally appreciated that it could repair hair from within the damage while washing gently.
