Here in my country, we have a popular hair treatment called creambath. Basically, you slathered hair treatment that feels lotion-y all over your head and massage it.
it may be a conditioner of sorts but at the same time it may also have oil (s) and some food (avocado) in it // i guess there are different recipes. on youtube there is a video of a lady making some on a TV program. i would say buy a jar/bottle and look at the ingredients and that should give you an idea .
what country are you from if i may ask?
