OK – all the hair restoration places give you the same medication / liquids at vastly inflated prices (just wrapped up in a fancy sales package and they try to tie you into a contract).
Heres what you need – see your doctor and get a script for Proscar, also get Regain extra strength and follow the instructions.
Basically, the Proscar will stop any more loss, and the Regain helps to regrow the lost hair (in some cases).
These are the active ingredients that you will be sold from an overpriced clinic.
Your doctor should be able to give you advice about these products and it will be much cheaper.

Hope this helps
