- Japan ranking listing: Gloss Absolu Vinyl Cream Hydra Glaze/Taiwan product page: 250mlThe Japan listing is Kérastase's Gloss Absolu Bain Cream Hydra-Glaze, 250ml, ¥4,180 (an anti-frizz/dewy-shine/deep-hydration series). The Taiwan page: Kérastase's "Glossy Shine Chanson Hair Bath," 250ml, with product copy "perfumed by the Grasse fragrance house, deep hydration, smooth radiant shine, anti-frizz," matching the anti-frizz, moisturizing positioning of the Japanese Gloss Absolu x Hydra-Glaze series, launched simultaneously as a brand-new product in 2026, with the 250ml volume matching exactly, determined that the Taiwan translation "Glossy Shine Chanson" corresponds to the Japan "Gloss Absolu" line. (Retailer: KÉRASTASE Paris (a momo brand flagship store)) The Taiwan product page does not spell out the "Cream Hydra-Glaze" sub-series code word for word; the same product was determined by checking the brand/series positioning, launch timing, and volume together; this series is a single style in Taiwan, with no other volume or formula that could cause confusion.
