I'm allergic to fragrances, which means that I can't use any of the hair products available for deep conditioning or styling.
I've read about girls using beer, soap or sugar-water to set their hair, and wondered whether this would be practical. Any experiences?
I also recall my mum sharing a hair mayonnaise conditioning treatment with me when I was little, but she can't remember how it was made. Egg yolks and olive oil, but what else?
