I love a good hot oil treatment! It gives me the feeling of a hot cup of cocoa of a cold winter day! It has been a part of my regimen since the start. However, I do it sporadically (mostly during the colder months), which I need to change and make it a regularly scheduled event even when it's warm.
'Pre-poo' is short for pre-shampoo treatment. It's the act of applying a conditioning agent to the hair to prepare it for the washing process. It can be done for a few minutes, a few hours or even overnight.
