Why is my hair turning green when I dye it black?

Black hair dyes contain a significant amount of blue pigments, which can mix with the yellow and gold tones that are naturally present in blonde hair. When these colors combine, they can create a greenish cast, which is often the reason why people end up with greenish hair after dyeing it black. It’s important to note that the greenish cast is not always guaranteed and may vary depending on the individual’s hair and the specific dye used.

Preparing the hair

Before you dye your hair black, it’s essential to prepare it properly. This will ensure that the color will take evenly and prevent any unwanted green tones. Here are the steps to follow:

  • Strip your hair of any existing color: If you have any hair dye in your hair, it’s essential to remove it before you dye your hair black. You can either wash it out or use a hair color remover.
  • Bleach your hair: To achieve a light blonde color, you need to bleach your hair. Use a bleach kit, and follow the instructions carefully. Avoid over-bleaching your hair, as this can cause damage. More: How Long Does It Take To Bleach Black Hair?
  • Separate your hair into two sections: Once your hair is light blonde, separate it into two sections. Use pins to keep the sections separate. This will make it easier to dye each half of your hair separately.

You will have prepared your hair for the next step of the dyeing process. In the next section, we will discuss how to dye each half of your hair.

Dyeing the hair

Once your hair is properly prepared, it’s time to dye it black. Here are the steps to follow:

  • Dyeing the white half of the hair with toner: The first step is to dye the white half of your hair with toner. This will cancel out any yellow tones in your hair, leaving it a cool white shade. Apply the toner evenly to the hair and follow the instructions carefully.
  • Dyeing the black half of the hair with black dye: Next, apply the black dye to the black half of your hair. Make sure to apply the dye evenly, so you don’t end up with patchy areas. Follow the instructions on the dye kit carefully.
  • Leave the dye in for the recommended time: Depending on the dye you’re using, you’ll need to leave it in for a certain amount of time. Make sure to follow the instructions carefully.
  • Rinse out the dye: Once the time is up, rinse out the dye with cold water. Use a handheld showerhead to make sure you’re rinsing the dye out evenly. Be careful not to let the dye from one side of your hair mix with the other.

You should end up with beautiful black hair without any green discoloration. However, the process doesn’t stop here. In the next section, we’ll discuss how to properly care for your hair after dyeing it black.

Rinsing and aftercare

After dyeing your hair black, it’s important to take proper care of it to maintain the color and keep your hair healthy. Here’s what you should do:

  • Rinse your hair thoroughly: Rinse your hair with cold water until the water runs clear. This will help remove any excess dye and prevent it from staining your clothes or towels.
  • Don’t shampoo your hair: Avoid washing your hair with shampoo for at least 48 hours after dyeing it. This will allow the color to set and prevent it from fading too quickly.
  • Use a color-safe conditioner: To keep your hair healthy and maintain its color, use a color-safe conditioner every time you wash your hair.
  • Avoid heat styling: Heat styling tools like straighteners and curling irons can damage your hair and cause the color to fade more quickly. Try to avoid using them as much as possible, or use a heat protectant spray if you do use them.
  • Protect your hair from the sun: UV rays from the sun can cause your hair color to fade more quickly. To protect your hair, wear a hat or use a hair product that contains SPF.

You can maintain your black hair color and keep your hair healthy and shiny. With proper care, your hair will look beautiful for weeks to come.
