I am wondering if the areas on the head which lose hair first in Male Pattern Hair Loss are the areas of the head which naturally release the most body heat (e.g. the temples/crown). Is there more blood flow near the skin surface in these areas?
Great thought, but no. Your hair loss pattern is genetic and it really has nothing to do with blood flow. If you lost hair and became bald (let’s say in the crown) then any hair loss will probably occur in the hairy area where the blood supply is more robust.
