If I'm in doubt about it I do a longer scalp massage/scrub with the low-poo, smooth it out down the length of my hair, and let it sit for a bit before I rinse completely. In a hurry one morning, I skipped the low-poo and just used my clarifying shampoo. That worked well also without having to wait. Anytime I do coconut oil I always apply the shampoo to my lengths too.

When I tried to do a coconut oil treatment that wasn't overnight, I did have to shampoo twice though.
