About 3 years ago at age 28 I noticed the hair in and around my crown area was quite a bit thinner than the rest of my head. So I did some research and found that Minoxidil might do the trick. It was cheap and effective for a lot of people. I ordered the Kirkland brand stuff, and began a routine. I remained with the same thinning look so after 3 years, I didn’t think that I was getting any benefit from minoxidil and then stopped it. I had a massive hair shed within a couple of months.
While you were taking minoxidil you may have been replacing your native hair with new hair that was induced by the minoxidil and you just didn’t see this ‘swap’ happening. When you stopped the minoxidil, all of the new hair induced by minoxidil which was addicted to it, fell out. You might try going back on the minoxidil.
