To create your own glitter hair spray, gather a spray bottle, ultra-fine glitter in one or more colors, and a non-aerosol liquid hair spray that has a removable top.
Fill the spray bottle most of the way with the hair spray, leaving a little room for the glitter. You may also divide a large bottle of hair spray amongst several smaller spray bottles to create different colors of glitter hairspray.
Add glitter to the spray bottle until it resembles a snow globe. The exact amount of glitter varies according to the size of the spray bottle. Use ultra-fine glitter, since it is less likely to clog the nozzle of the spray bottle, but feel free to experiment with other glitter if you have it handy. To save money, you may add the glitter directly to the bottle of hair spray.
If creating multiple colors of glitter hair spray or just adding glitter directly to a bottle of hair spray, be sure to add a label to avoid confusion.
