# How to remove chapter # and title from headings

I am using this code :

\documentclass{book}
\usepackage{fancyhdr}
\usepackage{fourier-orns}

\pagestyle{fancy}

\begin{document}
\chapter{First Chapter}
text of first chapter
\chapter{Second Chapter}
text of second chapter
\end{document}


I'd like to remove the text CHAPTER 1. FIRST CHAPTER that appears in the second page ...

I just added \fancyhead{} (and \lipsum to test even/odd pages).

\documentclass{book}
\usepackage{fancyhdr}
\usepackage{fourier-orns}
\usepackage{lipsum}
\pagestyle{fancy}
