@Chocolove sorry if I wasn't clear Little Ondine is 'non toxic' nail varnish: natural resin, organic colourants and water.
Having a quick look Miss Nella seems cheaper but it's branded at little girls.
In terms of hair products I've made hairspray using sugar water and vodka. I've not used it much (not having the spoons to put effort into hairstyle often) but it does have some staying power. It amuses me a little because I usually avoid refined sugar in food, but it does need to be white refined sugar, and I also don't drink vodka!
