How to touch up your roots without ruining the highlights: 3 infallible techniques

hair with light highlights

There are 3 techniques to touch up roots without ruining highlights:

  • T-zone technique
  • Technique for applying color to roots from the lower to the upper end
  • Root retouching technique with applicator


Now, which of the three techniques is best for your hair?

In a few moments, I’ll help you find out.

Firstly, let me clarify one very important detail.

To be able to touch up your roots without ruining your highlights, it is very important that the growth is at least 1cm. It is even better if it is 2cm long.

  Remember that the more growth your hair has, the easier it will be to touch up your roots. Also, the more likely you are to achieve good results.

Highlights can give your look a radical makeover. They give hair a special shine, and it’s also a very personal style. It’s almost impossible to find two identically colored heads.


All of this means that, in order to apply the dye more easily and causing less damage, it’s best to touch up the roots when they are approximately one to two centimeters long.

This length of growth will usually occur in about 4 weeks.


Now tell me the truth, do you have experience in dyeing roots, or would this be your first time?


If you don’t have much experience, then my recommendation is that you do it in a beauty salon. It’s a job that requires precision so as not to stain the rest of your hair with highlights.

If you have some experience applying hair color, and are willing to touch up your roots with your own hands, stay with me, because I will tell you:

What technique to choose for retouching your highlights?

If you don’t have much experience in the field of root touch ups, I advise you to choose the first option. Of course, this is only an advice; after all, it will depend on your experience or preference.


1- T-zone technique for touching up roots

without staining highlights

Do you know why this technique is called the “T-technique”?


Because you will have to do a middle parting on your hair to form a letter T, where the hair separates in two.


It is ideal if you have very little growth, because you only have to apply the dye on that line that you can easily visualize. This way your highlights will not come in contact with the dye you apply.


2- Technique for applying the color to roots from bottom to top

to better touch up the roots

This technique is for people who have more experience in coloring, as it requires more precision in the application of the dye so as not to stain the rest of the highlights.

You will have to pay more attention to the correct sequence of the steps to retouch the roots. In this case, the order of the factors will alter the product, that is, in your case, the results.


  • The first thing you have to do is divide the hair into four sections.

The first section will be defined from ear to ear. The next section will begin at the frontal growth line and end at the nape of the neck.


  • You will start the root touch up by the two back sections of the head, then splitting horizontally and applying the dye with a brush on the root.
 It’s very important that you touch up only the places where the hair has grown and has never been in contact with dye.  


  • Then you will continue to make other fine divisions horizontally and continue to apply the dye.

Remember to always apply the hair dye from the bottom up, with your head straight, without tilting it.


When you finish the application, you will notice that your hair is neatly flattened. If you notice any roots missing, it’s time to touch them up, and then leave the dye on for the exposure time indicated by the manufacturer.


3- Root touch up technique with applicator

You probably know the applicators that contain all the coloring kits. These applicators are easily available in pharmacies or hairdressing shops and are very economical.

So, to use this technique, the first thing you will need to have at hand is an applicator. Do you have it?

Then, let’s touch up the roots.


  • What you have to do is place the color cream and the peroxide inside the applicator and shake vigorously so that both products mix well.

Once you notice that the consistency of the cream is homogeneous and uniform, cut off the tip of the applicator. The tool is now ready.


  • Now it’s time to divide the hair into sections, to start touching up the roots.

Divide your hair into four sections from ear to ear and from the front growth line to the nape of the neck.

Then, make the fine partitions horizontally and start the application from the bottom up.


  • Always apply minimum pressure to the container, so that the right amount of dye comes out and allows you to make a precise and neat application.

If necessary, run your finger over the place where you applied the dye to spread the product correctly, but be very careful not to stain the highlights.

Once you have finished with the application, leave the product on for the time indicated.


Which color of dye to choose for touching up your highlights

The number one rule when touching up your color, especially if you have highlights, is to apply the dye only where it is needed, i.e. at the roots. If you apply hair color where there is already color, your hair will look dull, less natural and you will ruin the highlights.

Before choosing a tone, always make sure you pick the right color.  When it comes to touching up roots, you should always aim to choose a tone or two within your existing color range, meaning your base tone.  


The new, virgin hair tends to become darker, because it absorbs pigments faster.

Above all, think about your hair’s history, does it tend to get colored easily?


If so, choose a lighter color than your base color.

Don’t forget that after all, bleached hair is a sponge that automatically absorbs the pigment of the color. Therefore, I suggest you be very careful when applying the dye to your roots so that you don’t stain the highlights and leave no color flags.



You should touch up your roots thirty days after you have had the highlights, and only apply the dye to the growth, which will be approximately one to two centimeters long.

Any of the techniques I explained here for root touch up will allow you to do it in a precise and neat way, keeping your hair looking like the first day.

Now tell me, what technique will you choose to touch up the roots of your highlights without ruining them?
