Do you want to spice up your hair with salon trends but avoid salon prices? One of the simplest ways to save money on dying your hair is to style it at home. There are plenty of at-home dye options ranging from root-touch up kits to highlight kits to complete dye kits. A 
box of hair dye at the store ranges from $4-25, which is much less than you would pay at the salon. Unfortunately, a lot of women fear that dying their hair at home will result in a hair catastrophe! The good news is that there are plenty of ways to dye your hair successfully at home without damaging your hair or your bathroom.
Use petroleum jelly.
Before you dye your hair, apply a thin layer of petroleum jelly to your hairline, the tops of your ears, and anywhere else you don’t want the dye to stick. If this is your first time dying your hair, you may accidentally use too much dye, and the petroleum jelly will prevent you from having splotches of dye on your face and ears.
Use too little.
In the world of hair dye, it’s far better to use too little dye than too much. Too much dye means more random splotches of blue or brown to clean out of your bathtub, and if the color ends up being wrong for you, it means it’ll be more challenging to repair. Use a small amount of dye at first and, if the color works, use more as needed.
Don’t forget the strand test.
If you’re dying your hair for the first time, test the dye or bleach on a few strands of your hair before you do your entire head. This will give you a chance to make sure you don’t have an allergic reaction to the dye and that the color works for you.
Condition immediately.
One of the best ways to prevent drying out or damaging your hair while dying it at home is to condition your hair. For the best results, use both a wash-out and leave-in conditioner to keep your hair shiny, silky, and smooth after dying.
