Alternative to Local Styles method is not pulling in any CSS

webpack.config.js : Here is what it looks the loaders part looks like-

```
module: {
loaders: [
{ test: /\.jsx?$/, exclude: /node_modules/, loaders: ['babel?' + JSON.stringify(babelLoaderQuery), 'eslint-loader']},
{ test: /\.json$/, loader: 'json-loader' },
{ test: /\.pcss$/, loader: 'style-loader!css-loader!postcss-loader' },
{ test: /\.css$/, loader: 'style-loader!css-loader'},
{ test: /\.less$/, loader: 'style!css?importLoaders=2&sourceMap!autoprefixer?browsers=last 2 version!less?outputStyle=expanded&sourceMap' },
{ test: /\.scss$/, loader:
'style!css?importLoaders=2&sourceMap!autoprefixer?browsers=last 2 version!sass?outputStyle=expanded&sourceMap' },
{ test: /\.woff(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/font-woff" },
{ test: /\.woff2(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/font-woff" },
{ test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=application/octet-stream" },
{ test: /\.eot(\?v=\d+\.\d+\.\d+)?$/, loader: "file" },
{ test: /\.svg(\?v=\d+\.\d+\.\d+)?$/, loader: "url?limit=10000&mimetype=image/svg+xml" },
{ test: webpackIsomorphicToolsPlugin.regular_expression('images'), loader: 'url-loader?limit=10240' }
]
},
```

webpack-isomorphic-tools.js style modules part:

```
style_modules: {
extensions: ['less','scss','css'],
filter: function(module, regex, options, log) {
if (options.development) {
// in development mode there's webpack "style-loader",
// so the module.name is not equal to module.name
return WebpackIsomorphicToolsPlugin.style_loader_filter(module, regex, options, log);
} else {
// in production mode there's no webpack "style-loader",
// so the module.name will be equal to the asset path
return regex.test(module.name);
}
},
```

In my component the render method looks like this:

```
render() {
require('../../../styles/header_new.css');
require('../../../styles/common_style.scss');

return (

I seem to have followed all the steps but no CSS is applied at all.

Could I have some pointers on this?
