Formulation Deep Dive

The Overnight Repair Serum by Crown Affair is formulated as a high-performance water-based emulsion designed for nocturnal hair fiber restoration and cuticle smoothing. The base utilizes a sophisticated humectant system of Propanediol and Isopentyldiol to drive moisture into the cortex, while Dimethicone and Stearamidopropyl Dimethylamine provide immediate lubricity and static reduction for a refined tactile finish. Active performance is driven by a lipid-rich botanical complex featuring Limnanthes Alba (Meadowfoam) Seed Oil and Camellia Japonica (Tsubaki) Seed Oil to replenish the hair’s natural fatty acid content, working synergistically with Panthenol (Provitamin B5) and Arginine to reinforce structural integrity and moisture retention. The formulation is stabilized through a combination of Behentrimonium Chloride and Glyceryl Stearate, utilizing a preservation strategy that includes Methylpropanediol, Caprylyl Glycol, and Didecyldimonium Chloride for robust microbial control.
