Head lice treatments often come in shampoo or soap form. While they can be used in place of your regular shampoo, there are certain times in the day when it is best to apply these treatments for maximum effect.
The best time to use head lice treatments would be after work. Most treatment shampoos require you to let the treatment remain in the hair far longer than the average shampoo to allow the treatment to really soak in the hair and do its job. To do this, you do not want to be in a hurry and you want to set aside more time so you can give your hair a careful rinse afterwards. After work, before you go to bed, or during the weekends are the best times to apply any head lice treatment so you can make sure that you can follow the instructions and get the most out of the treatment.
