What S-Heart-S does

S-Heart-S is a French private company (operating as SARL DEUXS) that curates and sells premium scalp and hair care brushes developed by its parent operation in Japan. Founded in 2004 by Mr. Kinoshita, the company specializes in Shiatsu-inspired brush designs featuring nylon fibers of varying lengths and diameters (376 to 4,104 picots across the product line) positioned on epoxy resin bases that prevent water infiltration. The flagship Scalp Brush family includes the original 376-fiber classic for fine/normal hair, the 572-fiber Plus variant for thick/dense hair, the Cure White with three-step technology for treatment distribution, the Backstage and Plus Mini portable versions, and the Bijulie 3-in-1 that adds a roller for skin care. A now-expired patent (n° 3964227, 2002-2022) once protected the Bijulie's scalp-adapted design.

The company sells primarily through its own French-language e-commerce storefront (s-heart-s.com) with delivery limited to France, supplemented by wholesale distribution to prestigious French luxury retailers including Le Bon Marché, Galeries Lafayette, Printemps, and The Peninsula Paris hotel. S-Heart-S also serves professional hairdressers directly, most visibly as the official backstage supplier for Japanese designer YUIMA NAKAZATO's Haute Couture runway shows at Paris Fashion Week since June 2019. Products retail between €100 and €300 and have cumulatively sold over 1.3 million units across Japan, France, Switzerland, Belgium, Russia, and Monaco. Marketing leverages editorial coverage in Vogue and L'Officiel, organic social on Facebook and Instagram, and event-driven visibility through fashion industry partnerships. The business model is straightforward one-time hardware sales with no disclosed subscription, licensing, or recurring revenue components.

• Christophe Robin: Christophe Robin is a French luxury haircare brand known for scalp-care products (scrubs, masks, treatments).

• Mason Pearson: Mason Pearson is a heritage British premium hairbrush maker, famous for its boar-bristle nylon-and-cushion detangling brushes.

• Tangle Teezer: Tangle Teezer is a UK-based brand that pioneered the detangling hairbrush category with its two-tier flexible teeth design. It is a direct competitor in the detangling/gentle-brushing hair tool category, with broader mass-market distribution but increasingly premium pricing tiers.

Broad incumbents
