Can someone suggest a good dermatologist for hairfall problem in Jaipur?

I've been facing severe hairfall since past a few months and need to consult with a dermat ASAP. I've consulted with 2 dermats and they prescribed me some biotin tabs and a serum which didn't worked at all. So can someone please suggest a good dermat in Jaipur who prescribe meds only after finding the root cause of the problem (like any kind of deficiency)?
