It will probably continue until you are no longer hypo--6-8 weeks after starting Synthroid assuming the starting dose is adequate.

For me the hair loss trailed the onset of hypo symptoms by 4 or 5 weeks and it stopped falling out 4 or 5 weeks after I had recovered. When I had my recent uptake scan it didn't start falling out until after the proceedure, after I had resumed Synthroid for about a week but while I was still very hypo. I think the delayed reaction is why some people think Synthroid is the cause of their hair loss.
