Hairline HELP!!

[SE19]

I have been on Propecia about 4 months now, and it looks as if it is eating my hairline, my right hand side looks as if chunks have just fallen out over night, and my left also looks bad.

WHAT IS GOING ON?

I thought propecia was supposed to maintain hair you already had? This is definately very fast falling in the hairline as I notice a difference literally over night.

Does anyone have an answer as to what could be happening?

some reasurance perhaps?

Many Thanks
