My guess is that it is probably the famed castile soap which is made of pure olive oil which lathers minimal and cleanses really well. Also, it lasts reallyyy long so the price justifies the product.
Yes, being used to lather, it was frustrating to use it in the beginning but now I like it a lot. I would definitely suggest you to pick up some if you stay in Hyderabad.
