HOW IT WORKS

Artichoke leaves are rich in natural antioxidants including hydroxycinnamic acids and flavonoids. These compounds neutralise the free radicals generated by UV exposure and pollution before they can break down the hair's proteins and lipids, keeping the cuticle sealed and the hair fibre intact. 5,6

Artichoke Extract Works as a Safe Topical Antioxidant: Artichoke leaf extract demonstrated strong free radical scavenging activity when applied topically and was confirmed safe and well tolerated in human patch testing, supporting its use as an effective antioxidant in cosmetic formulations. 8
Artichoke Extract Protects Hair from UV-Induced Damage: Cynara scolymus leaf extract at 5% significantly reduced both protein degradation and lipid damage in hair exposed to UV radiation, with treated hair showing measurably better cuticle condition and fibre integrity than untreated controls. 9
Key Antioxidant Compounds in Artichoke Leaf Identified and Confirmed: This study identified and confirmed the key antioxidant compounds in artichoke leaves, finding that the leaves contain significantly higher antioxidant activity than the flower heads, with cynarin and chlorogenic acid among the most potent free radical scavengers. 10
