This. Used Dial bar soap when I was a mere wisp of a lad. IIRC we advanced to Dial shampoo.When I was a little kid I remember my grandmother lathering up my hair with a bar of soap. That's how they rolled in the olden days. None of this fancy bottled stuff.

Yes, Dove isn't a soap though. I've used Dove and had no problems, other than I can't stand the smell of Dove... Even the unscented stuff is too strong to my senses. Bar soaps are high in wax context. It will build up over time and have to be stripped, if you aren't a pomade kinda guy, and go au naturel.My hair is extremely short and for the past 20-25 years have only used Dove for everything.
