My hair could not handle leaving in conditioner. I recently left in my Body conditioner in my hair as a moisturizer, and my hair felt DRY and my scalp felt ITCHY. No beuno.

As for Yes to Carrots, did your like it 'cause you sealed the moisture with the oils? Did you do that previously with other conditioners?

Semi off topic, but I love Yes to Carrots leave in conditioner.
