Scalp Care Efficacy Evaluation for Premium Scalp Revitalizing Essence

This is a prospective, randomized, double-blinded, and placebo-controlled study to investigate the effects of Premium Scalp Revitalizing Essence on changes in the skin texture of human scalp skin. Sixty healthy adults aged from 18 to 60 will be recruited and randomly assigned into five groups, with 12 individuals in each group. Group 1 uses Placebo (Base formula without caffeine and panthenol); Group 2 uses the Base formula (Control with caffeine and panthenol); Group 3 uses Base + IGF-1 \& FGF-7; Group 4 uses Base + Centella asiatica extracellular vesicles; Group 5 uses Base + Centella Asiatica Exosome + IGF-1 \& FGF-7. Before using the test product, all 60 participants undergo the first scalp skin texture test. After 14 days of using the test product, a second scalp skin texture test is conducted; after 28 days of use, a third test is performed; after 42 days of use, a fourth test is conducted; and after 56 days of use, a fifth test is carried out. The scalp skin texture tests include measurements of skin (1) sebum content, (2) overall hair loss, (3) hair density, (4) scalp condition, (5) hair length, and other parameters. The Sebumeter® SM815 probe of the MPA580 device and the ScalpX Intelligent Scalp Diagnostic System will be used to measure the parameters of the study.
