Some Parts of My Hair Didn’t Dye, How Can I Fix it?

If some parts of your hair didn’t dye, it could be due to some of these three reasons:

  • Reason 1: The hair dye you applied was expired. In this case, you should recolor your hair and check the expiration date before.
  • Reason 2: You didn’t respect the exposure times, and you rinsed the dye out before it had time to work. The solution is also to re-dye your hair and leave it on for 45 minutes.
  • Reason 3: You didn’t cover all of your hair with the dye evenly. The solution is to reapply a dye and cover all of your hair. I’ll tell you a foolproof way to do this later.

Coloring your hair at home may seem like a very, very easy thing to do.

But surprises happen.

Suddenly, once you rinse the hair dye out, and your hair dries, you discover mesmerized that things didn’t go so well.


  There are spots in some parts of your hair as if you had applied a few brushstrokes of color.  

Alternatively, when you gather your hair in a ponytail, and you look in the mirror, you may notice that your back parts didn’t dye.


I don’t want to exaggerate, but I do ten color corrections a week to people who applied the hair dye at home, but the color didn’t stay even.

When I ask them what happened, the answers are almost always the same.

  • “I removed the dye early because I was in a hurry.”
  • “Does the dye have an expiration date? I never knew.
  • “I couldn’t cover the hair on my nape with the brush.”

Surely, you’ll feel identified with any of these situations. But we can’t change the past.

We can only focus on the present to achieve a better result in the future.


Therefore,   if some parts of your hair didn’t dye, the only solution is to dye your hair again. 

Let’s analyze each of the reasons you might have failed to apply the dye to prevent it from happening again.

Reason 1: Some parts of your hair didn’t dye because the product was expired

Where do people get the idea that hair dye has no expiration date?


In my opinion, all the products we use every day have an expiration date.

Hair products, including hair dye, are no exception, and I’ll tell you something else.


  Hair dye has an expiration date, and it must be properly stored.  

Try to think back.


Did you buy the dye you used recently, or did you have it stored in the bathroom cabinet a long time ago? Maybe you’ve had it for so long that you don’t even remember where and when you bought it.


Generally, dyes have a shelf life of about 2 years as long as they are properly stored.

To be properly stored, they should be kept away from heat, sun, humidity, and water.


Hair dyes contain photosensitive chemicals. It means that if the hair dye is exposed to direct sunlight, it can degrade.

If it degrades, it won’t have the appropriate effect on your hair when you apply it.


So,   before applying hair dye, always check that it’s not out of date. If you have stored it for a long time, check where it was.  

If the dye and developer cream are liquid when you open them, they’re not good and should be discarded.


If you suspect that your color didn’t stay even because the dye was expired, all you have to do is color your hair again with the same dye color.

That’s right. This time, just in case, check the expiration date.


Reason 2: You dyed your hair, and some parts didn’t look good because you didn’t respect the exposure time

let the dye work

We live in a crazy world that makes us think that we can’t waste a second of our day.

But that’s not true.


We need to stop and breathe.

You need to take the time to enjoy things, whether it’s reading a chapter of your favorite novel or applying your hair color.

Yes, why shouldn’t you make time to color your hair properly if you want to have great color in your hair after all?


  Permanent hair dye has an exposure time that you must respect.  

When I say “exposure time,” I mean that you must let the dye act for a certain amount of time for it to take effect.


  • The dye contains chemicals that need time to work.
  • For example, the developer or hydrogen peroxide is responsible for opening the cuticles of your hair so that the dye can penetrate and change the color.
  • Ammonia also needs time to fix the pigment inside your hair.

The whole process takes about 45 minutes.


You can’t rinse the dye out sooner because you’ll be interrupting the process.

  If you interrupt the process, some parts of your hair may not dye.  

What’s the solution?


You should reapply the dye with the same color and let it act according to the time recommended by the manufacturer, which is usually 45 minutes.

The exposure time of the hair dye is essential for your color to be even.


Reason 3: You didn’t apply the hair dye evenly

This is the consequence of a lack of coloring experience, and I understand you.

It’s hard and uncomfortable to color the back of your hair.


That’s why   my first tip if you don’t go to a salon to color your hair is to ask a friend or cousin or even your mom to help you with the dye application.  

After all, you can make it a social moment to share the latest news or enjoy a Netflix series together.


But if you don’t have someone who can help you dye your hair, I’ll tell you how you can do it yourself to make sure you properly cover all your hair with the dye.

Because if you didn’t apply the dye evenly, and there are undyed strands, you’ll have to dye your hair again.


Here is a step by step guide to correct the color by coloring again:

  • Separate hair into 4 sections, forehead to nape and ear to ear, holding each section with hair clips.
  • Start applying the dye to one of the back sections from root to tip.
  • Then, comb through that section with a medium-tooth comb or brush.
  • Repeat the procedure for each section.
  • When you finish covering all four sections with the dye, let your hair down and spread the rest of the product all over your hair.
  • Cover your hair with a shower cap to allow the chemical reaction to progress evenly.


Once the exposure time is over, rinse the dye out.

When your hair dries, you’ll notice that your color is even. That’s the easiest way to cover all of your hair when you color your hair at home.



You should check the expiration date of the product before coloring your hair. It’ll prevent your hair from being unevenly colored.

It’s also necessary to respect the exposure times and cover all the hair with hair dye to avoid leaving sections of your hair uncolored.
