Although you may have once adored your blue or green hair (or even a combination of both), you might now be looking for a change. Sure, you could visit a salon to alter your hair color, but if you’d prefer to remove the dye yourself, there are several methods you can try using easily accessible products, some of which you might already have. Regardless of the method you choose, keep in mind that it will take time to remove the dye from your hair.
Steps
Wash the dye out with shampoo

Determine if deep cleansing shampoo will be effective. Deep cleansing shampoo is a great product for removing temporary hair dye. However, if you’ve used a long-lasting dye, deep cleansing shampoo might not be powerful enough to fully remove the color. This method may remove some of the long-lasting dye, but it will require more time to see results.

Purchase a clarifying shampoo. You’ll need to buy a clarifying shampoo that isn’t specifically for dyed hair. This type of shampoo helps remove dye from your hair. Additionally, you’ll need to get a conditioner (it doesn’t need to be expensive).
- Suave Daily Clarifying Shampoo is a product you should try.
- If your hair is dry and frizzy, consider buying a deep moisturizing conditioner to provide essential nourishment to your hair.
- You can also opt for an anti-dandruff shampoo.

Consider adding baking soda to the shampoo. Baking soda is a natural bleaching agent, so when mixed with shampoo, it can help accelerate the removal of hair dye.

Wet your hair with warm water. Ensure the water temperature is comfortable for you. Warm water opens up the hair follicles and cuticle, making the removal of hair dye easier. Be sure to thoroughly wet your hair with water before shampooing.

Apply the clarifying shampoo. Pour a sufficient amount of shampoo into your palm and apply it to your hair. Gently massage the shampoo into your scalp with your fingertips. Squeeze out any excess foam (which may contain some of the dye). Ensure the shampoo is evenly spread across your hair. At this point, avoid rinsing the shampoo out just yet.

Pin your hair up. If your hair is short, you might not need to pin it up. Wrap a towel around your neck (preferably one you don’t mind getting dirty, as shampoo and dye may drip onto it and stain the towel).

Place a plastic shower cap on your head and heat your hair. Make sure the cap covers your entire hair and stays securely in place. Use a blow dryer to apply heat, but be cautious not to direct hot air to one spot for too long to avoid melting the plastic. The heat will help the shampoo strip the dye from your hair.

Leave the cap on for about 15-20 minutes. Afterward, rinse your hair with warm water. Apply shampoo to your hair twice more, rinsing thoroughly each time. Once you're done washing, only a small amount of hair dye will remain in the form of soap suds.

Apply conditioner to your hair. Ensure it is spread evenly throughout your entire head of hair. If your hair is long enough, you can pin it up. If not, simply let your hair hang naturally.

Use a blow dryer to heat your hair. When the hair is nearly dry, leave it for 25-30 minutes, then rinse out the conditioner with cool water.

Rinse your hair with cold water. This helps close the hair cuticles and locks in the nutrients from the conditioner. You'll notice that the hair dye will fade by about two-thirds. Wait for your hair to recover for about a day before repeating the process.
Use vitamin C to wash out hair dye

Mix 1000 mg of vitamin C with shampoo. You can purchase vitamin C in small packets, bottles, or powder form. Pour the vitamin C into a mixing bowl. If it's not in powder form, you can use the back of a spoon or a pestle (if available) to crush it into powder.

Add shampoo to the vitamin C powder. It's best to use a good-quality shampoo to keep your hair soft and healthy. Pour a slightly larger amount of shampoo than usual into the vitamin C powder and mix well. Ensure there are no lumps and that both ingredients are fully blended together.
- You can also add a little dish soap to the mixture of shampoo and vitamin C to enhance its dye-removal effect.
Wet your hair with warm water, then apply the mixture. Warm water helps open the hair follicles, making it easier to remove the dye. Apply the shampoo mixture to your hair, ensuring you spread it evenly so that it soaks into every strand, from root to tip.

Pin your hair up and cover it with a shower cap. This hair dye removal method can be a bit messy, so it's important to wear a shower cap while waiting for the mixture to take effect. You should also wrap an old towel around your shoulders since the dye might drip down. The shower cap will catch most of the dye, but it's safer to wrap the towel around your shoulders just in case.
- If you don't have a shower cap, you can use a plastic bag and secure it at the front, or use plastic wrap to cover your hair.

Allow your hair to soak in shampoo for about 45 minutes. During this time, the combination of shampoo and vitamin C will help remove the hair dye. After 45 minutes, wash your hair thoroughly.

Apply conditioner to your hair. This step is crucial to prevent your hair from becoming dry or tangled. This method works effectively for both temporary and long-lasting hair dyes, though it may vary depending on your hair type. You can repeat the process if the hair dye is still visible.
Use household products

Fill the bathtub with water and add bath salt. Bath salts, which are available at beauty stores or large supermarkets, are known to help lighten temporary hair dye colors (such as blue or green). Fill the bathtub with warm water and add a packet of bath salts. The longer your hair stays submerged, the more the dye will fade. After soaking, wash your hair and moisturize. You may need to repeat the process in 1 or 2 days if necessary.
- If you prefer, you can use a basin instead of a bathtub by adding water and bath salts to soak your hair.

Use dish soap. Keep in mind that dish soap can dry out your hair, so you will need to use conditioner afterward. Add 4-5 drops of dish soap to a small amount of shampoo (about the size of a coin). Wet your hair with warm water, then apply the shampoo-dish soap mixture. Leave it for 10 minutes, then wash your hair thoroughly.
- Be sure to use conditioner after washing with dish soap to keep your hair moisturized.

Washing your hair with laundry detergent water. Ensure that the detergent does not contain bleach or whitening agents to avoid damaging your hair. Wet your hair with warm water, then apply a spoonful of laundry detergent onto your hair. Use another spoonful if your hair is relatively long. Rinse thoroughly and apply conditioner to keep your hair healthy and strong.
Fading hair color with sunlight

Spend more time outdoors. Exposing yourself to natural sunlight for a few days can help lighten your hair color. A daily walk in the midday sun, when the sunlight is most intense, can do the trick. Just make sure to apply sunscreen to your skin and avoid staying outside too long to prevent scalp burns.

Use a hair styling spray. Apply a hairspray that promises to "hold your style" to your hair, then stay out in the sun for as long as possible. Afterwards, comb out the hair spray and wash your hair with an anti-dandruff shampoo. Finish by applying conditioner to restore softness to your hair.
Advice
- If you're unable to adjust your hair color on your own, it's best to seek the help of a professional hair stylist to achieve a flawless color correction.
- Always wear old clothes and drape a towel over your shoulders when dyeing your hair.
Warning
- Be cautious when using household products such as dishwashing liquid or laundry detergent. Avoid getting these products in your eyes, ears, mouth, or nose.
- Avoid applying brown or black dye purchased from the store on top of blue or green hair dye. Typically, this will result in a darker color with a hint of blue.
