First, I tried Herbal Essences' non-aerosal spray in the "Lily Bliss" fragrance. Though it is cheap, contains fewer chemical ingredients, and includes"cactus flower extract," it did not work very well and actually flattened my hair.
Next, I purchased "Thin to Thick," an all natural and organic hair spray produced by J/A/S/O/N Natural Products. Surprisingly, it does give my hair a bit more volume and succeeds in holding it in place. Though it does not quite work as well as an aerosol spray, it is a less toxic option, as all ingredients are naturally occurring.
