In this ultra-lightweight, water-based formula are hero skincare ingredients like fermented hyaluronic acid and micro-filtered aloe vera to provide immediate comfort and long-lasting hydration. This moisturizing, [no-rinse scalp serum](https://www.trendhunter.com/trends/dualpeptide-scalp-serum) can be used generously after cleansing, with Biolage recommending one drop for every inch of the scalp. Alternatively, it can be reapplied to a dry scalp or dry hair as needed. Clinically tested to hydrate the scalp for 24 hours in one use, this instantly nourishing serum is vegan-friendly, paraben-free, silicone-free, and suitable for color-treated hair. ## Trend Insights (Trend Hunter) - Score: 8.9/10 - Popularity: 94% | Activity: 96% | Freshness: 77% - Audience gender: 30% men, 70% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Fashion](https://www.trendhunter.com/fashion) > [Hair](https://www.trendhunter.com/hair) ## Key Themes ### What Makes This Trend Stand Out - **Skinification of Haircare:** Growing consumer expectations for facial-grade actives in hair products are redefining product categories and enabling multifunctional formulations that address scalp health alongside hair aesthetics. - **Water-based Scalp Serums:** Formulations prioritizing lightweight, water-based delivery systems are enabling rapid absorption and 24-hour hydration claims that challenge traditional oil- or silicone-heavy hair treatments. - **Fermented Hyaluronic Acid Adoption:** The incorporation of bio-processed hydrators like fermented hyaluronic acid signals a shift toward biotech-derived ingredients that offer enhanced skin/scalp compatibility and measurable clinical performance. ### Sectors Adopting This - **Personal Care and Cosmetics:** Brands and retailers face opportunities to expand product lines with hybrid scalp-and-hair solutions that command premium positioning through clinically backed ingredient claims. - **Dermatology and Trichology:** Medical practitioners and clinics can leverage scientifically formulated serums to offer targeted scalp treatments that bridge over-the-counter convenience and clinical efficacy. - **Ingredient Manufacturing and Biotech:** Producers of fermented actives and micro-filtered botanicals are positioned to disrupt supply chains by scaling specialty ingredient production tailored for scalp-focused applications. ## Related on Trend Hunter - [UV-Protective Haircare](https://www.trendhunter.com/trends/dove-uv-repair-glow-collection.md) - [PDRN-Powered Hair Serums](https://www.trendhunter.com/trends/pdrn-reedle-shot-brush-hair-serum.md) - [Rosemary-Infused PDRN Haircare](https://www.trendhunter.com/trends/rosemary-pdrn-hair-care.md) - [Tree-Planting Haircare Promotions](https://www.trendhunter.com/trends/surface-hair.md) - [Spring Skincare Sampling Boxes](https://www.trendhunter.com/trends/spring-testtube-box.md) - [Scalp Wellness Haircare](https://www.trendhunter.com/trends/the-balance-collection-by-tgin.md) - [Clinician-Prescribed Scalp Serums](https://www.trendhunter.com/trends/dermatica-hair-loss.md) - [Post-Procedure Recovery Formulations](https://www.trendhunter.com/trends/aestheticae-curae-kit.md) - [Professional Hair Spa Collections](https://www.trendhunter.com/trends/professional-hair-spa.md)
