Not Sure If I’m Losing Hair from MPB or From Significant Weight Loss

I am a 24 year old male who has lost a lot of weight in the last 8 months. I feel like my hair is thinning but am not sure. I haven’t noticed any excessive shedding, my hairline is the same, but my hair does feel a little thinner. I’m not sure if it’s due to weight loss or the beginnings male pattern hair loss (my family does have a history of it).

My question is would it be bad to get on Propecia now even if I am unsure as to whether or not i have male pattern baldness? and if i’m not balding would it be bad to start taking propecia for preventative measures? i.e. If I start propecia can it jump start male pattern balding?

and do you know of any places in Sacramento that do the miniaturization test?

Weight loss produces dietary problems which can cause hair loss, particularly if you are genetically prone to it. Genetic male pattern baldness (MPB) is the most common cause of hair loss or hair thinning in men. It occurs special “patterns” — as the term implies. If you have MPB, any good dermatologist can diagnose this problem and prescribe you Propecia (finasteride 1mg) as an option. Only a doctor can prescribe you Propecia. Propecia does NOT jump start hair growth from male pattern baldness. It slows it down as a rule.
