Thanks for your reply. Unfortunately it didn't work out. I also used the following alternative approach but the problem is still the same; that is, the header is missed in the first page:

\fancyhead{TEXT}
\usepackage{lastpage}
\pagestyle{fancy}
\lhead{TEXT} \chead{}\rhead ...

\pagestyle{fancy ...
