well dude i lost like 40 pounds
im six foot one i was like 190
i went down to like 150 last year
earlier this year i lost a ton of hair in the temple region
coincidence maybe
but i think it had to do with the subcutaneous fat layer on the scalp
when you loose alot of weight .....you loose it every where on your body
this includes your scalp and face
some speculate that mbp is exasperated with a decrease of the subcutaneous fat layer in the scalp
i think that was the case for me but i may be wrong and it was just my genetics
also as you age your subcutaneous fat layer on the scalp naturally shrinks
i think that might be your case since (i think) your a little on the older side "no offense"
cheers mate
