Sustainable Hair Care: Formulation, Physicochemical Characterization, And Performance Assessment Of Novel Dual-Phasic Bio-Derived Hair Serum

The study presents a sustainable, bio-derived dual-phasic hair serum as an alternative to silicone-based serums, addressing concerns about hair shaft damage from petrochemical products. The serum formulations (F1–F6) include essential oils like Meadowfoam seed oil, wheat germ oil, peppermint oil, and rosemary oil, along with polyols such as glycerol and sorbitol, and vitamins H and E. These ingredients provide natural conditioning, moisturization, and protection benefits. The serum demonstrated excellent physicochemical stability, with a suitable pH range for hair care, and enhanced cuticle integrity and surface smoothness as confirmed by SEM. Thermal analyses showed good compatibility and stability, while consumer assessments highlighted positive attributes and esthetic appeal. Antimicrobial testing confirmed satisfactory preservation efficacy. The study concludes that this bio-based serum is a sustainable and effective alternative to traditional silicone serums, offering enhanced functionality and supporting eco-conscious formulation design.
