[Report] "4 Stages of Hair Loss Risk"... Wallets Opened by AI Diagnosis

AI Pop-up Store at Hyundai Department Store Cheonho Branch
Free Experience Until the 16th
Hair Loss and Personal Color Diagnosis... Even Fashion Recommendations

"This is a level 4 risk of hair loss." The reporter, who had thick hair, felt a chill run down their spine. Having never worried about hair loss until their mid-20s, they took the scalp scan with a light heart, but the results were unexpected.

On the first floor of Hyundai Department Store Cheonho Branch in Gangdong-gu, Seoul, an AI experiential beauty pop-up store featured booths from three AI companies: Refilled, Twinit, and Samatdi. Visitors could check their hair loss status for free and receive personal color diagnosis and fashion suggestions.

Upon entering the ‘Refilled’ booth, where one could experience AI hair loss diagnosis, a store employee said, "I will touch your hair briefly," and brought a scalp scanner. The small device scanned the reporter’s crown. About a minute after the scan finished, an enlarged photo of the scalp appeared on the screen.

The unexpectedly revealing image made the reporter flinch.

"Is my scalp really like this?"

The analysis report, divided into three parts: forehead, crown, and back of the head, diagnosed a lack of hair follicles on the forehead area. The reporter, a woman in her 20s, was speechless when the employee explained that her hair loss risk was higher than that of a man in his 30s.

The scalp analysis diagnoses care type (dry, oily, sensitive) and risk level on a 5-step scale. The scalp scanner replicates the hair loss diagnosis experience from hospitals, having trained its AI data on over 400,000 scalp images. It analyzes hair loss risk based on the number of hairs per unit area, hair thickness, and the average number of hairs per follicle. Additionally, it compares the condition of the hair on the back of the head, classified as permanent hair, to assess how much the crown or hairline has deteriorated. It also incorporates data on scalp oiliness and inflammation, comparing these with average data by gender and age to calculate the final hair loss risk.

Shocked, the reporter was introduced by the employee to hair loss functional cosmetics containing cytokine ingredients. The employee emphasized, “Hair loss is more about management than treatment,” adding, “The scalp, like skin, needs consistent care.” Dr. Yang Mi-kyung, who developed Refilled cosmetics, discovered the 'cytokine' ingredient after 30 years of hair loss research. Cytokines are a type of neurotransmitter that promote hundreds of growth factors in our body. Recognized for its definite effect on hair growth, it has been patented in the U.S., China, and Korea. The employee recommended cytokine shampoo, booster, and ampoule for hair loss management. Although the regular prices seen on the website ranged from 38,000 KRW to 87,000 KRW, the event store sold hair loss care shampoo (31,500 KRW), hair booster (27,900 KRW), and eyelash dual ampoule (27,900 KRW) at about half price.

Next, the reporter tried a personal color diagnosis. At the ‘Twinit’ booth, a device resembling a photo booth caught the eye. Pressing the start button, aligning the face centrally, and taking a photo, the analysis results appeared in 30 seconds. The reporter had self-identified as a ‘summer cool tone,’ but the AI’s analysis differed: it was a winter cool tone. “Many people guess their personal color, but AI diagnosis often shows different results,” the employee explained. Scrolling down the screen revealed face shape analysis results. The AI meticulously analyzed the shapes of the eyes, mouth, and nose, producing results such as ‘puppy face,’ ‘wide lips,’ and ‘slim nose.’ The employee advised, “Since your philtrum and upper lip length are relatively long, shading adjustments can create better balance.” Regarding the analysis that the distance between the eyes and eyebrows was wide, the employee said, “This is common among East Asians,” and gave a tip: “Applying eyeshadow broadly can compensate for this.”

On the next screen, recommended colors matching the personal color appeared. The AI showed the best and worst colors side by side and also recommended the most suitable lip color. After the diagnosis, moving on, there was an experiential device at one side of the booth where visitors could virtually try on the recommended lip colors on the screen. Trying on several department store lip products suitable for winter cool tone, the employee said, “People with fair skin and winter cool tone often look good in purple shades,” recommending the Lanc?me Lip Idole Butter Glow in ‘Mauve Plum’ color that was tried on virtually. Visitors to the Twinit booth could also receive a free 10-minute ‘flash makeup service’ for face and lips at the Guerlain store on the first floor. At the Lanc?me store, a free gift of 1ml of Teint Idole Care & Glow Foundation and 1ml of G?nifique Ultimate Serum was offered. This was limited to the first 50 people per day.

The last stop was the ‘Samatdi’ booth, where fashion AI diagnosis was available. Standing in front of a large 65-inch smart mirror, the AI analyzed the reporter’s fashion in real time. The reporter was wearing a black corduroy shirt and gray jeans, which the AI described as ‘a cozy bear day fashion.’ On the vertical smart mirror to the left, the reporter received style recommendations that matched today’s outfit. Because the weather was clear, fashion items reflecting this were also suggested. Selecting the detailed option ‘20s, female,’ recommended items included DKNY’s cutting stitch wide pants and leather basic jacket.

The AI experiential pop-up store runs until the 16th at the beauty pop-up event space on the first floor of Hyundai Department Store Cheonho Branch in Gangdong-gu, Seoul. During the pop-up period, Refilled’s hair loss care products are sold at up to 50% off the initial retail price. At the Twinit booth, visitors can experience personal color and face shape analysis for free, with a 5,000 KRW fee for printing the results. A Hyundai Department Store official said, “We prepared this pop-up store so customers can directly experience various digital contents using AI technology,” adding, “We plan to continuously introduce digital contents applying the latest technologies.”
