How effective is washing hair daily with conditioner and apple cider vinegar rinse instead of shampoo?

I've never heard of such a thing. I hear a lot from older people that what you can eat can be used in your hair as a rinse out conditioner. Such as eggs and mayo. I personally, however, think that there are certain things made especially for the hair, but if you think it's gone make your hair healthier, go for it!!!!!
