This is my Denman. There are many like it, but this one is mine. Without my Denman I am nothing, without me my Denman is nothing.
It kinda looks like torture devise if you ever were crazy enough to use it as a normal brush. The bristles are hard in tight sections bundled together and would hurt any head. But just run the main section through your hair brushes and it pulls the hair strands straight out of the other brush, which in turn build up in the cleaning brush but are then really easy to remove. Next I use Johnson's No Tears Baby Shampoo at £1.69 for 300ml with a bit of warm water. Using the pointed end I ran this through the gaps at the base of the bristles to clear the dusty buildup on the brush. All that's left is to rinse and let it dry.
Final thoughts, it takes just a few minutes to do this process but it's worth it. I find it so simple to do and it means my hair gets greasy less often because of it. The cleaning brush is £3.99 but I think this is great value as it removes the hassle from the task at hand.
