Depending on what shade of blonde your hair is, there can be some coloration mistakes like hair turning green if you just apply the product on the hair. Today, we learn about the common color mistakes and the ways to avoid them while going from blonde to brown. We also discuss different ways to make it simple and convenient.

Why Blonde Hair Turns Green When Browned

When the hair is bleached, the melanin in the hair gets removed to lighten the tone of the hair. As this process damages the hair to a great extent, it loses its natural color and absorbability. So, when you dye your hair in brown, it does not absorb it properly. Due to this, blonde hair can get a bright green tint if colored brown.

Applying cold color shades on bleached hair gives the result of greenish tone because brown has equal parts of the three primary colors – red, blue, yellow. Blonde hair has no red pigments. So if you apply a color with a blue or green base, you get a green or blue hair. When you have blonde hair, use of ash dye can turn out to be a big mistake. You should be careful about dying when you want to go from blonde to brown.

How To Dye Blonde Hair Brown

If you intend to turn your blonde hair into a shade of brown, you should be extremely careful about the dye you use otherwise you can end up getting an unwanted shade. To avoid any hair-color mistake, there are two simple ways you can follow –

  • Use a warmer shade of brown
  • Prepare the blonde hair in advance

The first thing you can do to avoid your hair turning green is to use a warmer shade of brown. The problem with this method is that the result will not be so precise for the shade of dye you use. Alternatively, you can prepare the blonde hair by filling it. This means you fill the base tone that is not present by coloring it with red or gold to get it ready for brown. This step introduces the red pigments your hair should have to get the brown result and prevent turning green.

Filling Blonde Hair

To avoid turning your blonde hair green when coloring it brown, you can fill the hair with red or gold tones before dying. The tone you choose for filling depends on how light your blonde is and the present shade your hair has. You can do this easily by applying a warm tone before using the brown dye. You can either use a demi-permanent dye or colored protein filler to complete this step.

Demi-Permanent Dyes

These dyes can be used as fillers and you can do it well by choosing a shade that is at least a tone lighter than the brown you desire. A warm or neutral brown color can be easily done after filling the hair with a shade of red or copper. But for ash-brown, you will need to use a shade that is two tones lighter. This is because you should have some red tone to prevent your ash brown dye from turning green. However, you don’t want it to be so red that it looks too dark after applying your shade of brown.

Colored Protein Fillers

These products work great for porous hair as the protein they contain help maintain the porosity and prevent the dye from coloring your hair unevenly. Bleaching the hair to get a blonde shade makes it porous so protein filler is a nice way to repair it. For naturally blonde hair, it does not matter how you prepare the hair for brown. Colored protein fillers work easily and quickly but can sometimes give new color due to warmth.

Using a Warmer Shade

The other alternative to filling with red before dyeing it brown is to color it with a warmer shade of brown than desired. When this is done, a natural brown color results in ash brown while a golden brown would look like a natural brown. To use cooler brown shades, you get the desired shade by using one tone warmer than the actual shade. However, you should know that this trick slows down as you approach and stops working when you reach the shade of caramel brown. You need to use the exact tone if you want a caramel brown color.

Using Mixes to Dye Blonde Hair Brown

Using Mixes To Dye Blonde Hair Brown

If you want to dye your hair brown but have a lot of grey hair, you can try mixing different shades. Though the method is somewhat complex, it lets you color your hair dark despite your greys and requires no filling. To do this, you use a natural shade with the color you want to achieve. A natural shade is made up of all the three primary colors in the perfect proportion. It is also known as a neutral color. Being balanced, such a shade can dye grey hair brown and deliver precise results. It gives desired shade of brown when dying blonde hair as it reintroduces the missing base tones.

To use this method, you need to mix about 75 percent of neutral shade with 25 percent of the brown you desire. If you are using 4 ounces of dye, you can use 3 ounce of natural shade and 1 ounce of the original shade and add the developer according to the total amount. You should see that you mix dyes from the same brand. Then, you can apply the dye as you would do. The result is very close to the shade you desire and the difference becomes invisible when you reapply the original shade after this one fades.

We hope these tips help you achieve the brown shade you desire instead of making a coloring mistake that requires a correction.
