Hi there. At the outset, from your description, I take it you have a male pattern hair loss & some form of dandruff. If this is/was the dermatologists evaluation of your particular hair-raising issue, then I am in total agreement with the line of management. Please do remember to use the shampoo for not more than two times/week but leave it on wet scalp for 10-15 mts contact time at least. Also, I do hope the dermatologist has done all the necessary blood tests & appraised you of the possible side effects of finasteride, however rare. A foot-note will be to remember that hair fall takes place in no time at all where as for hair growth, one has to be patient! Good Luck & Godspeed. Dr Praveen Rodrigues MD
