Make sure to apply a good conditioner

It’s important to use a good conditioner after using a hair color product. Don’t just grab any old bottle of “conditioner” off the drugstore shelf and call it a day. In order to achieve the desired effect and maintain your color, you must choose the right conditioner. For example, if you have dark brown hair that has been colored brown with an ash base formula (meaning it’s slightly lighter than your natural shade), then you should use a moisturizing conditioner that contains keratin or silk protein in addition to other moisturizing ingredients like olive oil or argan oil.

Be careful not to overdo it with too much conditioner! Applying too much of this product will weigh down your hair and cause it to look dull and lifeless instead of shiny and healthy looking like we want for those summer days spent by the water at Coney Island Beach Club where everyone wears pastel shirts from Forever 21 because they’re cheap but also because they fit well on most body types so why not?

Use a purple shampoo

If you have dark brown hair, and you’re looking to tone down the color a bit, consider using purple shampoo. Purple shampoos are specially formulated to help remove brassy tones from dark hair. You’ll want to buy one that has both blue and violet pigments in it (for example: Pravana Vivids Violet Shampoo).

When buying a purple shampoo make sure that the brand doesn’t just include red dyes – red is not going to help your hair! This type of toning will only work on brunette or black shades. If you have blonde or light brown strands then stick with a green product instead (like Shu Uemura Art of Hair Color Refresher Green).

If possible avoid using any kind of permanent color on your strands for at least 6 months after using these products so as not to worsen brassiness even further.

Wash less often

Wash your hair less often.

• Use a dry shampoo between washes if you need to freshen up.
• Don’t rub your hair when you wash it. This can cause breakage and make it look duller, plus the scalp oils will get removed from your roots and cause oily hair further down the line.
• Use a sulfate-free shampoo (like Bumble & Bumble or John Frieda) for all-over cleanliness without stripping away color or damaging your scalp’s natural oils.

Get highlights!

If you’d like to dial back the power of your dark brown hair color and make it look sun-kissed, get highlights! If you want to do them yourself, be sure to use a semi-permanent dye that won’t damage your hair. Your best bet is probably a box at the drugstore; this one by Clairol is an affordable option.

To get highlights that are lighter than your dark brown hair color, ask a stylist for help. They’ll be able to tell you exactly how many shades lighter they need to go in order for the effect they want to achieve. Most salons offer this service as part of their normal menu options—if yours doesn’t, tell them what kind of look you’re going for and see if they can accommodate!

These tips will help you get rid of the dark brown hair dye gone wrong.

There are a few things you can do to lighten your hair color without having to dye it again. First, use a purple shampoo. This will help get rid of the dark brown hair dye gone wrong, and it’s easy to find in the grocery store or drugstore. If you’re unsure of which purple shampoo works best for your hair type and color, ask a hairstylist at the salon where you go for advice on what products would be best for your situation.

Secondly, mix some purple shampoo with conditioner before washing your hair with it; this will help lighten up your locks as well! You may need more than one wash session before seeing results because darker shades tend to stick around longer than lighter ones do (this is why people who want blonde highlights often need several rounds). The key here is persistence: keep trying different methods until something works out for you!
