The study aims to evaluate the efficacy of the Premium Scalp Revitalizing Essence on human scalp skin. A total of 60 healthy adults, aged 18 to 60, will be recruited and randomly assigned into five groups receiving different formulations. Participants will use the product once daily for 56 days, and their scalp conditions will be assessed through skin texture tests at multiple time points. Key parameters such as sebum content, overall hair loss, hair density, scalp condition, and hair length will be measured.
