Can I use water only method for daily sweat? I am a stay at home domestic goddess (it sounds better than out of work). I do a lot of outside yard work to keep busy, which makes my head sweat - wearing a hat or not. 

My question is - when I shower, can I just rinse off my head and hair or should I be using the water only method each time?  

The WO method I use is to preen my head/scalp and then brush to distribute the oil to the bottom. Then preen my head/scalp with just water.
