This paper aims to investigate the effects of brushing on the improvement of scalp and hair conditions. Data analysis adopted SPSS v. 17.0 statistical program. The significance level was around 5%. Then frequency analysis, cross tabulations, ANOVA and t-test were executed. The results were as follows; The dead skin cells were significantly reduced 4 weeks after testing and the unclean scalp conditions due to seborrheic dermatitis was also improved. Pores were also cleared. The scalp and pore conditions improved more 8 weeks after the test than 4 weeks after the test. It was confirmed that scalp and pore conditions were close to normal conditions by significant improvement 12 weeks after the test. Hair thickness increased by 0.006 mm 4 weeks after, by 0.015 mm 8 weeks after, and by 0.040 mm 12 weeks after the test for the test group. It increased by 0.003 mm 4 weeks after, by 0.008 mm 8 weeks after and by 0.020 mm 12 weeks after the test for the control group. The results indicated that brushing was effective as hair became thicker for the test group. Lastly, self-awareness of hair loss was reduced in the test group which performed hair care after brushing. The control group didn`t show any significant difference even though it performed hair care without brushing. The test group demonstrated high satisfaction on the improvement of gloss, hair care and strength of hair.
