I wash my hair every second day, otherwise my irritable scalp becomes unbearably itchy. But maybe it's the frequent washing with all those chemicals which has made it irritable?? Hmmm... interested to see how you go PZ. Not sure I could get through the itchy stage if I tried it!! Going to the holiday house next week, could try it while I'm there and not going to see anyone I know! Does the baking soda deal with the grease? And where do I buy coconut oil?? I have looked for it for my very dry hair but I can't find it!
