10 Ways to Remove Blue Dye From Hair

Method 1: Vitamin C

Method 1

The vitamin C method works by using its acidity, which oxidizes the blue dye so it loosens and can be washed away. It’s probably one of the best ingredients to wash your hair with.

If your blue dye is especially dark, try using this method first since it’s the fastest and safest way that won’t affect your natural color. It is effective on permanent and semi permanent blue hair dye.

You gradually lighten the color by about 1-2 tones as you go along, so expect repeat washing for complete dye removal of the blue hair dye.

Use a vitamin C gel instead of vitamin c tablets or vitamin C powder to ensure that it dissolves better in the mixture. It can be more difficult to find, but it’ll be worth the trouble.

  1. Mix the vitamin C gel and your usual shampoo.
  2. Work the vitamin C mixture into wet hair that’s been soaked in warm water or hot water.
  3. Make sure to cover each hair strand with the vitamin C mixture.
  4. Cover your hair with a shower cap, then let it sit for an hour. You can check it every 5-10 mins to see whether the blue dye is coming off.
  5. Rinse with warm to hot water. Your hair may feel dry at the end, so use a conditioner afterward.

Method 2: Dishwashing Soap

Method 2

Do you know how dishwashing liquid removes oils and food residue on dishes? Well, the cleansing agent found in dishwashing liquid can also strip off the blue hair dye from your hair.

This method best works on semi-permanent dyes, and it will take repeated dish-detergent-washing to completely get rid of that stubborn blue dye from your hair.

  1. Mix an equal amount of shampoo and dishwashing liquid.
  2. Soak your hair with warm or hot water before applying the dish soap or dishwashing liquid mixture evenly on your hair.
  3. Leave for 10 minutes, then rinse off the dishwashing liquid.
  4. Dishwashing liquid can dry your hair, so make sure to condition afterward.

Method 3: Sun Exposure

Method 3

Most colored hair enthusiasts know to avoid the sun if they want to prolong their color. In this case, since we want to get rid of stubborn blue hair dye, maximize the sunlight and use it to make the blue dye fade.

However, be prepared to be extremely patient since this will take the longest out of all the methods listed here. Its success rate also varies; those with originally dark or brown hair that’s unbleached have better chances of benefiting from sun exposure.

  • Simply expose your head to the sun over a period of weeks. A good way is to take long walks when the sun is the brightest.
  • While you should avoid wearing anything over your head, stay safe in the sun by keeping hydrated and wearing sunscreen.

Method 4: Bleaching

Method 4

We use hair bleach to lighten hair, so it’s one of the quickest ways you can use to remove blue hair. BUT TAKE CAUTION. Bleaching will affect your natural color as well. We recommend trying it out on one strand to see how strong the bleach is before proceeding.

Bleaching is so effective that it’s better to have a professional hair stylist or at least a friend help you with this process, if possible. Leaving the hair bleach on for too long can be dangerous to your hair because as the bleach strips the blue tint off, it can also damage your strands.

The worst case is, you’ll be in over your head as your light, over-bleached hair starts breaking off to the touch.

To avoid such a drastic scenario, prepare a timer, gloves, and other protective equipment so the bleach won’t accidentally get on anything else.

  1. Mix equal parts bleach powder and water to make your bleach bath, no need for peroxide.
  2. Apply to your hair in sections, keeping at least one inch away from the scalp using an applicator brush, and leave on for 10-15 minutes.
  3. Check your hair every 5 to 30 minutes before rinsing.
  4. Follow up with shampoo and conditioner to get the bleach off.

Method 5: Clarifying or Anti-Dandruff Shampoo

Method 5

Clarifying shampoo and anti-dandruff shampoo on their own are like extra-strength shampoo meant to remove dandruff and other buildup on the scalp. This deep cleaning property makes it a good choice for removing blue hair dye, though it won’t be a one-time hair dye removal.

The process of using shampoo could take around 10 to 15 washes to completely wash your hair out from the blue tint.

Use clarifying shampoo or anti-dandruff shampoo when you’re removing semi-permanent dye by following these guidelines:

  1. Use the clarifying shampoo the same way you would with regular shampoo. Since you’re trying to remove blue hair dye, ensure that the shampoo covers all areas.
  2. Leave the clarifying shampoo mixture for a few minutes before rinsing it out. Condition the hair to prevent your hair from drying out.
  3. Towel dry your hair. Since your hair is dryer than normal because of the clarifying shampoo, it’s a lot more vulnerable to heat styling.
  4. Stagger the clarifying shampoo washes over a few weeks to decrease the burden on your hair so it won’t dry out.

Method 6: Baking Soda

Method 6

Some people use baking soda as another easy remedy for removing blue hair dye because it has sodium bicarbonate.

It is similar to how bleach strips off the hair dye since it contains a cleansing agent. However, it is not as strong as bleach in this case and works best with semi-permanent hair dyes.

  1. Mix equal parts of the baking powder soda and liquid dish soap or clarifying shampoo.
  2. Wet your hair with warm to hot water before you work in the mixture. Work it into a good lather.
  3. Let it set in your hair for up to 10 minutes. Then, rinse it off.

Method 7: Bath Salts

Method 7

Bath salts are made out of Epsom salts and baking soda, so you can guess that it has similar properties to the baking soda method. It is also more effective on semi-permanent hair dye.

Here are some guidelines you should follow when using Epsom salt:

  1. The easiest way to use bath salts is to just use how it was meant to be used. Run a bath, or fill a basin if you’ll just be using it on your hair.
  2. Sprinkle the bath salts and get in there! Make sure to soak your hair completely.
  3. You’ll know that the salts are effective when you see blue hair color in the water.

Method 8: Opposing Color

Method 8

If you’re aiming to just change the color of your hair, consider coloring over your hair until you reach the desired shade.

To do this, you need to color your currently blue hair with the opposing color.

  • Check on what side of the color spectrum or color wheel your current shade falls under.
  • Look at which colors are on the other side. The opposite of blue hair color is on the red or copper shades.
  • Choose how you will get colored: You can get this done at the hair salon or try your hand at a home coloring kit.

Method 9: Color Remover

Method 9

You can use color removers for your blue hair. They come in two types: color reducers and color strippers. Color reducers are the gentler kind, which is perfect for hair that’s already been dyed.

The difference of a color remover with color reducers is that instead of stripping off the blue color, they shrink the blue color molecules of the blue dye. These are then washed away by the water.

Color reducers come with their own set of instructions, so you only need to follow what’s written on them.

Take note; you might notice a distinct, lingering smell from the product. They’re definitely not recommended if you want to keep your hair blue.

Something similar to color removers are blue and purple shampoos. Blue shampoos tone down naturally warm orange tones, while purple shampoo removes yellow tones which is perfect for maintaining white or platinum hair.

Method 10: Lemon Juice

Method 10

Similar to vitamin C, the juice from lemons also use acidity to remove the blue pigments. You can use it alongside baking soda for a more noticeable effect.

Some steps you should follow:

  1. Mix an equal amount of baking soda and juice.
  2. Leave the mixture on for only a few minutes before rinsing it off.
