The study investigates the potential of botanical extracts to improve scalp conditions by reducing oxidative stress, which affects hair and scalp health. Using both chemical and biological antioxidant mechanisms, 10 botanical extracts were tested for their ability to combat reactive oxygen species (ROS). The study employed ORAC testing, a Nrf-2 cell assay, and a 3D human keratinocyte model to evaluate antioxidant activity. A 4-week consumer study with 56 participants using a leave-on treatment containing a botanical extract showed a reduction in oxidized lipids on the scalp. The results indicate that incorporating botanicals with antioxidant properties into hair and scalp care products can enhance scalp health.
