Where the Original French Hair Spa Built Its Stage for Scalp Diagnosis — The René Furterer × ChoiceDx Partnership

In 1957, stylist René Furterer opened the world's first hair spa in Paris. Built on the belief that healthy hair begins with a healthy scalp, his original philosophy — Étheirologie — became the brand's foundation through a three-step care method: Prepare, Cleanse, Treat. René Furterer was also the first to bring plant-based ingredients into hair care. A philosophy rooted in the scalp itself — now meets ChoiceDx.

The technology René Furterer chose is ChoiceDx, CTK's AI-powered scalp diagnostic solution.

ChoiceDx uses a compact, scope-type device to capture precise scalp imagery, visualizing key indicators such as sebum, flaking, and sensitivity as data. Salon staff can review the results on screen together with the client and recommend tailored treatments — making consultations both more accurate and more persuasive.

Proven through more than 1 million cumulative scans at Olive Young stores in Korea, this technology now graces salon windows across Paris, demonstrating its value in the European hair care market as well. Where the heritage of a hair spa founded in 1957 Paris meets CTK's AI diagnostic technology, a 69-year brand philosophy gains a new language: data.
