This pre-and post-trial (quasi-experiment) aimed to explore the effectiveness of effectiveness of herbal in Thai Geographical Indication (GI). That was local hair serum products for people aged 30-60 years in upper northeastern Thailand. In total, 13,637 people were chosen for the study during January 2021 to May 2022. The samples were divided into experimental groups and control groups, with 26 persons in each group. Data were collected from the sample groups by interviewing at 0.90 confidence and then analyzed using:Descriptive statistics: percentage, average, standard deviation; and Inference statistics: odds ratio and 95% CI, independent t-test, and paired t-test.

The results showed that risk factors for hair loss were staining, bending, stretching, and environmental factors (p < 0.05). Compared with the control groups, the growth rate of the experimental groups increased from 0.16 to 0.82 centimeters (p< 0.0001), the rate of dandruff decreased from 30.10 to 8.34 (p = 0.028), and the rate of hair loss decreased from 14.56 to 10.19 (p< 0.0001). The effectiveness of reduced hair loss and dandruff, and increased hair growth among the experimental groups was better than for the control groups (p < 0.05). In addition, the sample groups were satisfied with the hair serum products from local herbs at the moderate-to-good level at 57.7%.
