pre shampoo treatments are an all day day/weekend type activitiy. I do them maybe every other month because the whole process takes so dang long.
For my regular shampoos I use elucence or devabrown no poo or I mix curlisto's chocolate shampoo with some conditioner. There are a few good ones out there that I discover from time to time, but I think for laziness sake, I keep going back to the same usual suspects.

I dont have enough hair to make sectioning worthwile. I just take my time and rinse thoroughly
