What old school product do you still rely on from time to time?

Which old school product would you consider trying again?

Although I can’t say I rely on it, I’ve recently revisited Nexxus Humectress. The ingredients aren’t the best, but when I first went natural, it always left my hair very soft and moisturized.
Chicoro, a beautiful natural and author, uses hair grease (Vitapointe and Vaseline)to seal her moisturized ends. My hair has been so ridiculously dry lately that I may get around to trying that too!

By the way, old school can mean ‘back in the day’ or ‘back when you were relaxed’ or ‘pre hair ingredient knowledge.’
