It appears that most of us nevertried body wash. So, comparison is difficult. I am thinking of using body wash. I shall again write a post in this thread after using body wash.
soap and body wash are used to clean our body while bathing. In our India most of the people use soap but in foreign countries like california they use body washes
Soaps basically dry out our skin and body washes make our skin supple and soft because the liquid will be absorbed by the body and the body wash will create a thin layer of moisture on our skin so that we donot lose out on water.
I suggest you to use fiama-di-wills (ITC) body wash which is violet color.It has even green,orange color body washes.The colors are for ornamental purposes only.It comes with a loofah and I think it will cost around 75/-.
There is Palmolive body wash and also LUX body wash(which katrina kaif models it).I have used all these brands and concluded that fiama di wills violet color body wash is good. It gives a good deo smell to the body and you can feel the change in your skin in 3 days.
