  • Salon hair dye doesn’t last longer than box hair dye.
  • The difference between the two kinds of dyes has nothing to do with the duration. Rather, it has to do with the quality and the way they weaken your hair.
  • Apart from how long the dye lasts, a professional hair dye will leave your hair and scalp in perfect condition.
  • It will also cover any gray hair better, so you may feel it lasts longer.
  • On the other hand, a box dye, although it lasts the same time, will dry out your hair. And after applying it, you’ll need to use moisturizing products.

Are you about to dye your hair and think a professional dye might last longer than a box dye?


At first glance, it might seem that way.

But, as I was saying,  it’s not actually true that professional dyes last longer  than the ones you can buy at the store.


However, for several reasons, professional dyes are of better quality than the ones that come in a box, as we’ll see in this article.

If you still can’t make up your mind, stay and read the characteristics of the two types of dyes so you can choose the one that suits you best.

Hair salon dyes don’t last for longer, but they are the best option for your hair

preparing the hair dye

 While professional dyes don’t last longer than box dyes, their quality is superior. 

They are formulated with the latest technology. These dyes feature, in most cases, premium quality pigments. Although professional dyes don’t last longer than box dyes, their high quality makes the color look firmer and brighter.

Also, since they’re of higher quality,  they damage hair less,  as it doesn’t become dry and dehydrated.


Some dye brands recommend that after you apply the professional dye, you should only rinse your hair with water.

That is to say, with these professional hair dyes you don’t need to shampoo afterward. Because  their excellent quality means that, just by rinsing with water, the hair cuticles seal themselves again. 

But that’s not all: these dyes will also take much better care of your scalp. Do you know why?


It’s because after applying a professional hair dye, your scalp will be moisturized and this allows your hair to grow normally.

But wait, the most important part is still to come!


The best thing about professional hair dyes is that they have a  covering power that’s far superior to box dyes. 

These dyes have the power to cover gray hair much better. For this reason, they may seem to last longer, but in truth, they last the same amount of time as box dyes.


So, what if you’re picky about your hair? Even if they don’t last longer, professional dyes are what you need:

  • You’ll cover any gray hair much better.
  • You will get flawless color coverage.
  • Your hair will have a dazzling shine and silkiness.
  • Your hair will retain its moisture and look amazing.


As you’ve seen, there are many reasons why hair salon coloring with professional hair dyes is preferable. But let’s now see what happens with box dyes: do they last for less time?


Box dyes don’t last for less time, but they do dry out your hair

Box dyes have  a lower price than professional dyes.  And, as you know, their duration is the same as that of a professional dye.

So are box dyes and professional dyes the same?


Of course not.

 Box dyes are generally made with lower quality components. 

For this reason, there are no assurances that you’ll get 100% successful results with a box dye.

Nor can we assure you that the shine and color will be long-lasting. Because  box dyes are not as long-lasting. 


On the other hand,  the low quality of the dye could affect the health of your hair, drying out the hair fiber  and, in more serious cases, the scalp.

It could even cause flaking, dandruff, or seborrheic eczema.


In addition,  box dyes have less covering power  than professional dyes.

In fact, light-colored box dyes won’t fully cover gray hair.

Therefore, if you’re going to use a box dye, I recommend you choose the right shade so you won’t have any unpleasant surprises later on.


However, if you’re not too fussy about the color or if you have no choice but to buy a box dye, don’t worry!

Be sure to look at the composition on the package, so you can choose the best dye to use at home.

3 tips for maintaining your hair after applying a box or professional hair dye

Keratin treatment in the salon

After you dye your hair, it’s very important you nourish it.

This will help to close the cuticles, which will make the color last much longer.

It will also  improve the health of your hair. 


  • Use flax or argan oils once a week.
  • Apply hair masks every 10 to 15 days.
  • Get a keratin shock, hair botox, or hair lifting, especially if you’ve just dyed your hair to cover bleached hair.



Because when covering bleached hair, whether you used a professional or box dye,  the color will fade during the first few washes. 

In these cases, proper hair nutrition allows the color to last over time.


Conclusion: box dyes and hair salon dyes last for the same amount of time, but professional dyes are better

Dyes are dyes, the durability is the same. With all the information you have here, you’ll be able to evaluate which one to choose: box dyes or hairdresser’s dyes.


We’ve seen that  although they don’t last longer, professional dyes have more covering power and leave your hair healthier. 


On the other hand, box dyes dry out the hair, which means you need to work a little harder to keep it healthy by incorporating nourishing treatments.

Make an appointment at the salon and  leave it up to your hairdresser to apply the dye. 

You’re sure to leave the salon with flawless hair. Don’t hesitate, GO FOR IT!
