Pre-poo is a moisturizing treatment done prior to shampoo. Often those with tightly coiled dry textured hair use a conditioner and oil the day prior to wash day to help make the defangling process easier. Some have even found that using a pre poo helps the hair feel more moisturized after wash day. This is likely the case for those who wash their hair on a regular basis and does not allow for a lot of product to build up prior to wash day.

I would recommend that you use an inexpensive conditioner and oil since you will be washing these out the following day or even the same day a few hours later. There are brands that offer a detangling pre-poo product that you can buy or you can pick a leave-in conditioner that is relatively inexpensive and pair it with an oil such as olive oil, coconut oil, or grapeseed oil. You should try to detangle your hair as you are applying the pre-poo to help make your wash day easier. You can apply the pre-poo in sections to make the process more manageable.
