Premium Haircare Promotion with Luxury Silk Backdrop

[Format] Professional e-commerce product main image, square 1:1, premium haircare promo over a cool silky backdrop. [Colors] Background flowing silver-blue silk waves over a deep blue base (#2b4a8c range); a frosted white bottle with a sky-blue label; translucent blue mini bottles; white and navy type; a blue formula band along the bottom; no frame border. [Layout] The left column stacks the headline, a blue membership pill and a grey sub-pill; the large pump bottle stands on a glass podium at the right with two minis in front; a wide blue calculation banner closes the bottom edge. [Subject] No people. A tall frosted-white pump bottle with a sky-blue label reading "MUYU LU 500ML" in fine caps, flanked by two small translucent blue pump bottles with tiny lettering, all standing on a reflective glass slab. [Headline] Left, bold navy caps on two lines: "Thicker with every wash" then "Hair so full it needs thinning". A blue pill reads "Join our store membership" with a grey pill beneath: "2 body-wash samples as a gift". The bottom blue band shows "Event price $289 = $499 - $100 - $100" in white with "$289" boldest. [Badges] The membership and gift pills are the promo badges. [Mood] Glossy, salon-grade and persuasive; silky blues promising visible density with transparent deal math.
