I've been trying to work out something that I like for my hair, and it is difficult. If you haven't been using a vinegar rinse (I, personally prefer a citric acid rinse) then yeah, your hair would be weird. It's amazing how the rinse makes your hair feel... I believe it's because the ph of soap is very alkaline and our hair should be slightly acidic, so the vinegar brings is closer to where it should be. That being said, I haven't been that wild about my bar soaps on my hair, but so far, I'm loving my liquid soap! I just tried a new batch on my hair last night and it's so soft and shiny this morning!
