Semi-permanent hair coloring usually lasts for eight to 20 shampoo applications, yet factors such as the condition or porosity of your hair, the quality of the semi-permanent coloring and your hair texture affect the length of time that coloring naturally fades or is removed. However, you may apply a semi-permanent color to your hair and decide to remove it the day after application. Removal of the semi-permanent coloring is not recommended in one day; however, there are some steps that you can follow to attempt removal of coloring.
Things You'll Need
Shampoo your hair as many times as possible using very hot water and a shampoo high in sulfur content. After several washings, you should notice the color fading.
Use hot oil treatments to strip semi-permanent coloring from your hair follicles. Since the condition and type of hair affects this procedure, you must pay attention to the effects of Step 1 and Step 2 on your hair. If you notice color fading with the hot oil treatments, continue to apply and rinse hot oil from your hair; however, if you do not notice any fading, continue on to Step 3.
Apply dish washing liquid or liquid laundry detergent to your hair. These agents will remove semi-permanent color and dry out your hair, so you should use either conditioner or hot oil treatments in between wash and rinse cycles.
Soak your hair in lemon juice and vinegar for 10 minutes if you have had the semi-permanent hair color on your hair for at least one week. It is not a safe to apply lemon juice and vinegar to your hair within 24 hours of a semi-permanent color application. Your hair will turn green, and you will have to seek a hair care professional if your hair becomes severely damaged.
