According to a recent LinkedIn post from Gisou by Negin Mirsalehi, the company is spotlighting product testing for its Honey Gloss Ceramide Therapy Hydrating Shampoo & Conditioner through its ongoing “Gisou Lab Series.” The post describes a “Light Reflection Test,” using a gloss-ometer to quantify how much light reflects off the hair’s surface as a proxy for shine.

The content emphasizes that smoother hair cuticles are associated with higher light reflection and longer-lasting gloss, with the post suggesting results of up to three days. It also notes that testing was conducted by an independent third-party laboratory, which may be intended to lend credibility to performance claims and support premium positioning in the competitive beauty and haircare market.
For investors, this focus on scientific validation and behind-the-scenes R&D storytelling could signal an effort to deepen brand differentiation and justify pricing power. By highlighting measurable product benefits and lab-based testing, Gisou appears to be targeting consumers who value efficacy and transparency, factors that can underpin brand loyalty and support revenue growth in the prestige personal-care segment.
