TLDR Coloring shampoos for gray hair may cause gene mutation, reproductive issues, and skin damage, needing stricter regulation and expert consultation.
The systematic review discusses the potential health risks associated with the use of coloring shampoos, particularly those used to cover gray hair. The main ingredient of concern is 1,2,4-trihydroxybenzene (THB), which is currently unregulated in Korea and can cause health issues including gene mutation, reproductive disorders, and damage to the skin barrier. This damage can lead to hair loss and other health issues. The review calls for stricter standards and regulations for these products, as well as further research into the potential harm of these ingredients. It also emphasizes the importance of maintaining a healthy scalp condition through sufficient analysis and consultation with experts.
