For a plastic-free hair rinse, go Indian

Over at Life Less Plastic, I was pleasantly surprised to see that the best non-plastic hair rinse options are some Indian recipes that have been used for centuries. 
The common ingredients: shikakai (the fruit of Acacia concinna), amla (the fruit of Emblica officinalis, the Indian gooseberry), henna (made from the leaves of Lawsonia inermis), etc. And our very own oils of coconut, sesame and mustard.
So, for those of you who still have hair left to rinse, do try these at home.
And if you don't know by now, the word shampoo draws its roots from India.
