74 SCALP CARE
consumer demands for both performance and environmental responsibility.
The relevance of proven effectiveness In the current cosmetics landscape, consumers are increasingly informed and discerning, seeking products that deliver tangible results. This heightened demand for efficacy has driven the importance of scientifically substantiated claims in product development and marketing. Clinical studies have demonstrated the
effectiveness of novel scalp care actives in improving hair health. For example, formulations incorporating natural ingredients such as improved exosomes, plant-derived polysaccharides or microalgae extracts have shown promising results. These components, obtained through biotechnological processes, contribute to enhanced hair strength and vitality. Furthermore, plant-derived active ingredients
are finding more potential in hair care products, targeting concerns like hair fall treatment and regulation of the sebum. These innovations underscore the potential of biotechnology in developing effective scalp care solutions. An example of such innovation is SCH
ShellCare® Scalp, an encapsulated cosmetic active by Special Chemicals that combines plant-derived actives with advanced peptides. This multifunctional ingredient targets multiple therapeutic aspects of scalp health, demonstrating a 44.83% reduction in hair loss and a 27.31% increase in hair density in clinical studies over 150 days. Additionally, it has been shown to reduce
IL-6 levels by 27%, TNF-α by 36%, and enhance antioxidant potential by 33%, making it a comprehensive solution for scalp care.
Formulation potential Integrating advanced scalp actives into cosmetic formulations requires careful consideration of delivery mechanisms to ensure stability and efficacy. Encapsulation technology has emerged as a pivotal strategy in this context. Encapsulation involves enclosing active ingredients within a protective shell, such as liposomes or polymeric walls, to isolate them from environmental factors and control their release upon application. This technique offers several benefits, as follows. ■ Enhanced stability: Encapsulation protects sensitive actives from degradation caused by light, air, or other environmental factors, preserving their potency over time. ■ Controlled release: The encapsulated actives can be engineered to release gradually, ensuring a sustained effect and reducing the need for frequent application. ■ Improved formulation aesthetics: Encapsulation can convert liquid or oil-based actives into powder or bead forms, enhancing the texture and sensory properties of the final product. By employing encapsulation and other
advanced formulation techniques, cosmetic scientists can effectively incorporate potent scalp care actives into products, delivering targeted benefits while maintaining product stability and consumer appeal.
PERSONAL CARE October 2025
A new era in hair care Maintaining optimal scalp health is fundamental to achieving strong, vibrant hair. A well-nourished scalp provides the necessary foundation for robust hair growth, while imbalances can lead to dryness, dandruff, and hair loss. Recognizing these challenges, the cosmetics industry has increasingly embraced targeted solutions to address specific scalp concerns, reflecting a broader trend toward personalized and effective treatments. Innovations in scalp care—from microbiome-
friendly formulations to the incorporation of potent antioxidants—are transforming traditional hair care. These advances, underpinned by rigorous scientific research and clinical validation, not only enhance product efficacy but also build consumer trust in an era where evidence-based claims are paramount. Moreover, the industry’s move toward
sustainable and technology-driven formulations, including methods like encapsulation and green extraction processes, is setting new standards in product development. As consumer awareness continues to
grow, the demand for products that deliver measurable results will undoubtedly shape the future of the cosmetics industry. The integration of cutting-edge biotechnology and sustainable practices promises to drive further innovation, ensuring that tomorrow’s hair care solutions effectively address evolving scalp concerns while promoting overall hair vitality.
