Alaska Hairdresser and Barber Certification Practice Exam

Semi-permanent color is described as non-oxidative and temporary because it does not require a developer or oxidizing agent to penetrate the hair shaft and change the natural color. This means it does not cause permanent alteration to the hair and gradually fades with washing, making it a good option for those who want to try a new color without committing to a long-term change. Demi-permanent and permanent colors both use an oxidizing agent to penetrate the hair and create more lasting color changes. Neutral tones, on the other hand, refers to a range of colors that are neither warm nor cool and can be used to balance out unwanted/red tones in hair.
