Shiseido Tsubaki Premium EX Intensive Repair Conditioner Treatment 400ml is a Japanese conditioner-treatment for damaged, dry, and chemically processed hair. The formula uses Camellia Japonica Seed Oil (Tsubaki oil) as its hero ingredient alongside Royal Jelly Extract, Sodium Acetylated Hyaluronate (a modified hyaluronic acid), Soybean Seed Extract, and Hydrolyzed Conchiolin Protein (pearl protein) for repair and shine. Four silicones (including Amodimethicone, which bonds to the most damaged sections of the hair shaft first) smooth the cuticle and reduce frizz. An uncommon addition: the INCI includes a UV filter (Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) that most conditioners do not carry. The 400ml bottle is a full-size product for daily or weekly use. One honest note: the four-silicone formula can build up on fine or low-porosity hair over time if you do not use a clarifying shampoo.
