Hair mousse = Clothes Starch?

A strange thought occurred to me this morning after a shower. 

I recently permed my hair, and as lovely as it looks, it insists on the use of some sort of hair stiffening lotion/cream/serum when its wet, so that it may set into lovely curls when dry. I've never been one to use or propagate the use of unnecessary products and cosmetics, however Hair Mousse seems to have become a must in my hair maintenance routine the last month. 

This morning however, I happened to wear a low back dress which made the wet mousse come in contact with my skin, and so when it dried,  it ended up feeling like a film of starch on my back. Which made me think!Both Hair Mousse and Starch serve the same purpose- temporary stiffness, which if stretched  the stiffness disappears. 

This reminded me of what my grandmom said people of her generation did to starch cotton sarees in Kerala. As rice is the staple food of that region, most households stored the starchy water after cooking their rice and later that afternoon dipped their washed cotton sarees in it and hung it out to dry on their terraces/fields. The result was a perfectly starched cotton saree. All this of course much before the advent of chemical starch available in stores today. 

And now for my theory - if I were to rinse my hair out in Rice water after a shower and let it dry, would it serve the same purpose as hair mousse? A safer, healthier more natural product wouldn't you say?
