powershell - write-output in loop losing header -

pretty new powershell , playing code here ran cannot find reply to. have function gets $serverlist containing server name , service name , returns output status of each service. have in loop running every few seconds, first run of function contains column herders, after data, no headers. what's deal here!

function servicestatus() { $objoutput = @() foreach ($objrecord in $serverlist) { $obj = new-object system.object $servicestatus = get-service -computername $objrecord.server -name $objrecord.service $obj | add-member -membertype noteproperty -name server -value $objrecord.server $obj | add-member -membertype noteproperty -name service -value $objrecord.service $obj | add-member -membertype noteproperty -name status -value $servicestatus.status write-output $obj } } for(;;) { $currentdate = get-date clear-host write-host service checked: $currentdate servicestatus start-sleep -milliseconds 5000 }

when looping, default behavior append info without headers.
