[미용]A Study on Hair Damage and Awareness Improvement in Darkening Shampoo and Hair Salon Dyeing Abstract(4페이지)
The study was conducted in parallel with a survey and experiment on 25 women from their 20s to 60s. The survey evaluated the perception, frequency of use, and satisfaction of darkening shampoo and hair salon dyeing, and the experiment measured the degree of hair damage. As a result of the analysis, both products received positive perceptions, but the satisfaction of hair salon dyeing was higher. Increased frequency of use was correlated with increased hair damage, and in particular, hair salon dyeing caused significant hair damage at all ages.
