The Difference Between Semi-Permanent And Permanent Hair Colour?

Semi-permanent hair colour like Manic Panic doesn’t contain harmful chemicals and relies on vegan friendly natural ingredients that sit upon the top of hair. Manic Panic dye partially penetrates the hair shaft with smaller colour molecules. 

Permanent hair dyes contain ammonia and require peroxide to penetrate and bond with the hair shaft. Manic Panic is gentle and doesn’t require any mixer.
