Maintaining colored hair can be expensive. If you've recently had your hair dyed, but the color is too dark, there are steps you can take to save yourself another hair salon session. It is possible to lighten the hair up to a point, but don't expect to accomplish a miracle. If your efforts turn out to be useless (and you really can't stand the color of your hair), you may have to resign yourself to going back to a professional.
Steps
Method 1 of 5: Act as soon as you have had your hair dyed

Step 1. Rinse your hair with hot water
The heat will open the cuticles of your hair, allowing more of the dye to escape. Soak your hair completely in the shower or in a sink.

Step 2. Use shampoo
Wash your hair with a lightening shampoo that is not suitable for dyed hair. Use it immediately after you've had a color made that isn't right for you. It should remove some of the fresh dye from your hair. Take a small dab of shampoo (or the amount recommended on the package) and apply it to your wet dyed hair. You don't have to manhandle them, but the shampoo should work in more vigorously than when you just wash your hair.
There are thousands of suitable brands that you can buy from any store that sells shampoo. Just make sure you choose a lightening shampoo that isn't made to protect the color

Step 3. Apply conditioner
After scrubbing your hair with the lightening shampoo, you need to moisturize it in order to reduce the aggressive cleansing effect of the shampoo. Apply a generous amount of conditioner. Take a large knob of the product, work it into your hair from root to tip and rinse.
If possible, it is advisable to wait a few days before attempting to remove the dye by rubbing your hair, as it needs to recover from the chemical processes used to color it. However, if you need to remove the stain as soon as possible, try to repair the damage as much as you can by applying conditioner
Method 2 of 5: Combine baking soda and shampoo

Step 1. Mix baking soda and shampoo
Mix two glasses of baking soda with a quarter glass of lightening shampoo in a non-metallic bowl. The alkaline baking soda will open up your hair and allow the lightening shampoo to remove color more effectively. Mix the two products with a whisk.
If you have hair that hangs below shoulder level, you may need to use three glasses of baking soda

Step 2. Wet your hair with hot water
The combination of heat and baking soda will open up your hair cuticles nicely.

Step 3. Apply the mixture
Work it into damp hair with your hands or with a spatula. Cover your dyed hair well so you don't end up with an uneven color.
Be careful not to get shampoo in your eyes. You can wrap a towel or tea towel around your head to prevent the mixture from getting onto your face

Step 4. Rinse your hair
Remove the mixture after five to fifteen minutes. The time will depend on how much stain you want to remove. The more pronounced you want the effects, the longer you need to leave the mixture in place. Do not leave it for more than fifteen minutes. If this time is insufficient, repeat several times.

Step 5. Blow-dry part of your hair to check the color
Since it may need to be rewashed and the heat can damage the hair even more, dry only a small portion. If the color is right for you, great! If not, prepare a new mixture of shampoo and baking soda and repeat the operation.

Step 6. If necessary, prepare the mixture again
If your hair is still not light enough, you can start over for better results. You can make a more potent mixture by adding a tablespoon of powdered hair bleach to the basic recipe. When using bleach, remember to wear gloves.
When you're done, avoid styling with a heat device for a day or two. The coloring and bleaching processes both damage the hair
Method 3 of 5: Use shampoo

Step 1. Take the following things
A little shampoo, a little bleach and a little conditioner. Mix the same amount of these ingredients in a bowl and mix them well.
You can get them in cosmetics stores, in certain supermarkets, hairdressing salons or on the internet

Step 2. Apply this preparation to your hair
Wet your beautiful hair and dry it lightly with a bath towel then apply this mixture after putting on gloves to protect your hands. Start at the roots and work your way to the tips.

Step 3. Protect your hair
Put a shower cap on your hair and keep it on for 10 minutes. Do not leave it on anymore, as this can damage your hair.
If you don't have a shower cap handy, you can use cellophane paper

Step 4. Rinse off
Rinse your beautiful hair thoroughly and then use a conditioner to protect it. You can also apply a deep-acting conditioner for a longer lasting effect.
Method 4 of 5: Make a vitamin C paste

Step 1. Crush fifteen to twenty vitamin C tablets in a bowl
You can use a pestle and mortar or something that won't damage the bowl.

Step 2. Add anti-dandruff shampoo to the crushed pills
A small amount is sufficient. Just add enough to form a paste with the powder. Mix the two ingredients with a whisk.

Step 3. Wet your hair with hot water
The heat will open the cuticles of your hair and allow the mixture to drive off more dye.

Step 4. Distribute the mixture through your hair
You can apply it with your hands. Fully cover dyed hair. If you don't apply the paste on a regular basis, you could end up with an "interesting" pattern in your hair.

Step 5. Leave the paste in place for an hour
If necessary, cover your hair with a bathing cap. After an hour, rinse your hair with cold water to remove the mixture.
If you have dry hair after removing the paste, moisturize it with conditioner
Method 5 of 5: Apply hydrogen peroxide

Step 1. Pour hydrogen peroxide into a spray bottle
For best results, you should apply the product to your hair using a spray bottle. If you pour it directly on your head, you won't know if you've covered all of your hair.
Without a doubt, hydrogen peroxide is the most unpredictable and possibly the least effective option. This method does not work against the dye and chemicals already in your hair, but adds another product on top of it. Use it with care

Step 2. Spray the product evenly on your hair
Select the setting that produces the finest steam. Hold the spray bottle about three inches from the hair you want to lighten and cover your eyes with a hand or a tea towel when spraying.
- Hydrogen peroxide is not harmful to the skin, but can burn the eyes. If you get it in your eyes, rinse them with cold water.
- If you go out in the sun, it can lighten your hair, but can also dry it out. If you go out with peroxide in your hair, you should be aware of the potential effects of the sun on it.
- Hold your hair in the necessary position with bobby pins or barrettes so that you can spray only the hair you want.

Step 3. Rinse your hair
Rinse them off with cold water after thirty minutes. If you leave the hydrogen peroxide on longer, your hair may dry out or bleed too much. If you apply too much peroxide, your hair can easily take on an unpleasant orange tone.
