The formulation of hair serum by using butterfly pea flower

The butterfly pea (Clitoria ternatea L.) flower is a rich source of polyacylated anthocyanin (ternatins), flavonol glycosides and other phenolics that offer antioxidant, anti‑inflammatory and pigmenting functions useful in hair-care formulations. This review synthesizes botanical and phytochemical data, extraction and stabilization strategies, formulation design for hair serums, evaluation methods, safety considerations, and future research directions integrating recent mechanistic and application-focused literature. Where relevant, findings from organoid and hair‑biology models are used to link ingredient action to hair follicle physiology.
