"SOPHISTANCE," a fermentation skincare brand run by SDI Co., Ltd., will launch its first hair care products, "SOPHISTANCE Gentle Repair Shampoo" and "SOPHISTANCE Gentle Repair Conditioner," on Wednesday, September 2, 2026.
These new products apply the brand's original "ultra-concentrated fermentation" technology and are characterized by an approach to the hair concern of "hollowed hair."

Original hair care focused on "hollowed hair"
SOPHISTANCE has so far offered skincare products that bring out the skin's natural beauty using its original "Bikatsukin®︎ fermented liquid*¹."
The company says the fermentation technology cultivated through this research was applied to hair care, leading to the development of this shampoo and conditioner.
The company explains that "hollowed hair," which occurs when lipids and proteins inside the hair are lost due to UV rays, dryness, coloring, aging and other factors, is the cause of hair concerns such as lack of volume, waviness, dryness and frizz.
It says SOPHISTANCE's hair care products were found to work on this "hollowed hair" by combining the same fermented ingredient used in its skincare with yuzu extract.

Shampoo features: replenishing moisture with "ultra-concentrated fermentation"
"SOPHISTANCE Gentle Repair Shampoo" is characterized by a springy lather rich in fermented ingredients.
It aims to envelop damage, replenish moisture inside hollowed hair and bring out supple beauty from the core.
A carefully crafted additive-free formula
It contains no silicone, mineral oil, ethanol, parabens, phenoxyethanol, synthetic fragrance, coloring, petroleum-based surfactants or animal-derived ingredients.
1. A fermentation beauty formula unique to SOPHISTANCE
According to the company, fermented ingredients tend to lather poorly when used in large amounts, but through its own research it achieved a springy fermented lather rich in the patented ingredient "Bikatsukin®︎ fermented liquid*¹."
While removing dirt from pores, it also cares for the skin's resident microbiota, supporting a scalp environment that leads to shiny hair.
2. Contains serum-level*² moisturizing ingredients
A rich, serum-like texture has been achieved.
Ingredients that are more than 97% naturally derived, such as fermentation-decomposed yuzu seed extract and Argania spinosa kernel oil (argan oil), wrap hair and scalp in moisture.
3. Mild cleansing ingredients that protect moisture
It uses mild cleansing ingredients centered on sodium cocoyl methyltaurate, sodium lauroyl methylalaninate and cocamidopropyl betaine.
This removes dirt while protecting moisture, gently removes excess sebum clogging the pores, gives firmness to the hair roots and adds volume. It washes hair to be fluffy at the roots and supple and manageable through the ends.

Conditioner features: intensive repair for glossy hair
"SOPHISTANCE Gentle Repair Conditioner" was developed to lead to glossy hair full of moisture even after drying.
Skincare-level*² emollient ingredients intensively repair hollowing damage and fill the cuticle with a veil of moisture, leading to a smooth, well-contained silhouette.
A carefully crafted additive-free formula
It contains no mineral oil, ethanol, parabens, phenoxyethanol, synthetic fragrance, coloring, petroleum-based surfactants or animal-derived ingredients.
1. Intensively repairs damaged areas
Repairing ingredients such as penetrating pseudo-ceramide*³ intensively repair damage caused by friction, coloring, dryness, heat and more.
It aims to even out the cuticle and lead to beautifully glossy hair down to the ends. The company says that by turning damage-care ingredients into fine particles and fixing them on the hair surface, it suppresses an oily film feel and achieves a light, smooth comb-through.
2. A unique formula that keeps water inside the hair
The patented ingredient "Bikatsukin®︎ fermented liquid*¹" and other skincare-level*² moisturizing ingredients penetrate deep into the hair.
NMF (natural moisturizing factor) holds water, protein and lipids, leading to a finish that is supple to the core. In addition, Argania spinosa kernel oil (argan oil), rich in moisture-retaining linoleic acid, is said to keep hair moisturized and give it a beautiful shine.
3. Heat care that makes the most of your dryer's heat
An acid-heat bonding ingredient*⁴ uses the heat of the dryer to adhere to the keratin protein inside the hair.
It protects CMC (lipids), which is important to the hair structure, and repairs split ends and breakage. It firmly protects the cuticle from damage caused by dryers and hair irons, and is said to lead to a finish with a smooth comb-through that stays light and well-contained to the ends.
