Here’s how to cover up blonde highlights with brown hair dye:

Step 1: Read The Manual

The first step in dying your hair is to read the instruction manual. It’s important to always read the instructions or manual that came with the hair dye, especially regarding safety and allergy precautions.

If you have any allergies or injuries on your scalp, you need to read the instructions to check if it is safe for you to use.

The manual will contain important information like how to mix the dye, apply the dye, and how long to leave the dye on.

Step 2: Separate Hair

Comb and separate your dry hair into four even sections. This will help you apply the dye evenly throughout the entire head. If you have thicker or curly hair, it may help you to separate your hair into even smaller sections.

Use a wide tooth comb to brush out any tangles, making applying the dye evenly a lot easier.

Step 3: Mix The Dye

Mix the dye with the developer by following the provided instructions. Typically, this just involves pouring the dye into the developer and mixing it. All the bottles will be labeled, so you will know exactly what to do.

Step 4: Apply The Dye

Now comes the most important part of dying your blonde highlights brown: applying the dye. Working on one section at a time, apply the brown dye evenly from root to tip. Double-check that the dye is applied evenly and there are no dry patches.

You will know that you have saturated all hair strands when there is no hair dye left in the bottle. Be sure to wipe your head off any dye that may have gotten there accidentally.

Step 5: Let Color Develop

Leave the dye on your head for 40 to 45 minutes, or whatever the instructions say. Do not leave the dye on for any longer than instructed, as this will not result in the brown looking darker.

Step 6: Rinse

When the time is up, you must rinse out the excess dye with lukewarm water until the water runs clear. How long this takes will depend on your hair thickness and length.

Step 7: Apply Conditioner

The final step in dying your hair is treating it. Hair dye can be quite damaging thanks to the chemicals, so using a conditioner afterward is highly recommended.

Some hair dyes will come with a conditioning treatment that you can use after dying. Or you can use a deep conditioner.

The brown dye over blonde highlights process is pretty similar for both permanent and semi-permanent hair dye. It is best to wash your hair and dry it before applying semi-permanent hair dye.

Can Brown Hair Dye Turn My Blonde Highlights Green?

Blonde Highlights Turned Green after Dying it Brown

Yes! Brown hair dye can turn blonde highlights green, especially if you bleach your hair to add blonde. When your hair turns green, this usually means that the underlying pigments in your hair have shown up during the dying process.

It’s all about primary colors. Depending on the shade you choose, the bleached blonde will have added yellow undertones, and the brown dye will have blue pigments. When mixed, yellow and blue create green, hence the reason your blonde highlights are now green.

Another reason why brown hair dye can turn blonde highlights green is if your hair is very porous. Bleaching your hair is one way of making it extremely porous. Porous hair is weak and will absorb the undertones of the brown dye.

To ensure a successful outcome and avoid the dreaded green hair, you must invest in quality products designed for colored hair and regular trims from a professional stylist.

Another good trick is to avoid swimming in chlorinated pools, as the chemicals can turn your hair green.
