Formulation Deep Dive

California Naturals Re:GRO Anti-Thinning Scalp Serum is formulated as a targeted, water-based treatment designed to address hair density and scalp health. The carrier system utilizes a blend of Aqua, Aloe Barbadensis Leaf Juice, and Panthenol (Vitamin B5) to provide a soothing, humectant-rich base that ensures effective delivery of actives without heavy residue. The formulation strategy centers on a synergistic complex of Capixyl, Biotin, and Caffeine to stimulate the scalp and support follicle vitality, while botanical inclusions such as Rosmarinus Officinalis (Rosemary) Leaf Oil and Serenoa Serrulata (Saw Palmetto) Fruit Extract provide secondary support for thinning hair. Stability is maintained through a Carbomer-based gel network and a preservative system consisting of 1,2-Hexanediol, Caprylyl Glycol, and Ethylhexylglycerin to ensure microbial integrity.
