The problem may sound ridiculous but your answers will help me resolve a big doubt. I know soap generally has the effect of removing "fat" from skin, thus drying it, but I don't know what effect it can have on something other than skin, in my case, hair... BTW, I know soap and shampoo are two different things, yeah ;-)
For example, what if there was a coincidential contact between soap used for hand-washing and hair?
The problem with using a soap as shampoo is it is generally harsher than even the harshest shampoos. Probally with the exception of Dove.
