Color strippers are one of the most effective ways to fade hair, according to Aronson. And there are at-home versions that won't destroy hair: Demelo says that the L'Oreal Paris Colorista Haircolor Remover, $6.48, will not cause damage to skin or hair, but it's effective enough to eliminate excess tone.

Other options include Punky Colour Colour Off Hair Color Remover, $15.99, the ammonia-free Ion Color Brilliance Hair Color Remover, $5.79, and ammonia- and bleach-free Color Oops Hair Color Remover, $11.99.

No color strippers? No problem. Tish and Snooky present a quick, gentler method for correcting an unsatisfactory hair color: Mix baking soda with equal parts shampoo. Leave the mixture on hair for five minutes before rinsing with warm water. They suggest following with a hot oil treatment, since it will also help remove color, plus, it will prevent damage.

Other DIYs include using dish soap to strip off too-intense color or applying lemon juice. The acidic properties in the latter will reduce the intensity of hair color, according to Tish and Snooky. After all treatments, use a good conditioner to keep tresses looking their best.

Something you probably wouldn't think of is going out in sunlight without a hat to fade color. Just be aware that the sun can damage hair, like skin, so limit exposure. You don't want to burn your scalp or dry out hair.

As much as some people might not want to go to the salon, know that it's always an option. If you got your hair dyed professionally, you might want to return to the scene of the crime — because if you're not happy with the original service performed, the salon will likely offer to correct it, free of charge.

Be aware that the salon treatments are likely going to be stronger. Or, they could try one of the previous hacks. Tish and Snooky reveal that the pros might give hair a bleach bath, which is a mixture of shampoo and bleach. (They do not recommend anyone attempting it at home because it may be damaging to hair.)
