what happens when you use regular soap to wash your hair
Bar soaps especially contain waxes that can coat the hair shaft and make the hair look limp and lifeless. Hand soaps often have grease-cutting agents that will strip the hair and scalp of protective oils that can end up making the hair feel dry and harsh. Even body wash can contain oils and emollients that will build-up in the hair and will mean that the hair looks flat and limp.
