Does dyeing your hair make it thinner or thicker?

colors that hide thin hair

Have you noticed that your hair looks thinner and you think it’s your hair dye’s fault? Has your hair seemed thicker and harder to manage because of volume since you’ve dyed it?


Well, your hair being thicker or thinner doesn’t have anything to do with dye. Do you want to know why?

  • Because dye doesn’t modify your hair fiber at all. Even if you religiously dye your hair once a month, it will always be the same thickness.
  • But what can make your hair look thinner or thicker is the color you dye it.
  • That’s why if you have thin hair, it’s a good idea to use darker colors and if you have thick hair, you should go for lighter ones. In a few seconds, I’ll tell you more about it.
  • What dye can affect is your hair’s health, since large quantities of bleach can dry out your hair.


 As you can see, dye making your hair thinner or thicker is just one of many myths that go around about hair dye. 


Dyeing your hair doesn’t change how thin or thick it is, the only thing it can do if you use it often with lots of developer is weakening your hair.

That means, you might end up with weaker hair, but it would be the same thickness as always. If you’re worried about that, don’t get too caught up in your worries, because I’ll tell you how you can strengthen it so you can be confident when you dye your hair.


What isn’t a myth is that some colors or color techniques can make your hair look thinner or thicker.

Is your hair so thin it seems like you don’t have that much of it? Do you want to hide some of your hair’s volume?


If so, stick around because I’m going to tell you:

  • What color dye you should use on thin hair
  • What color dye you should choose for making your hair look thinner
  • How to take care of your hair depending on how thick or thin it is


Let’s start busting those myths then.

Do you have thin hair? Dye your hair one of these colors and it will look thicker

If you have thin hair, you should use dark colors, and the darker the color is, the better.

Don’t freak out! I don’t mean that you have to dye your hair black. Dark brown and brown are also dark colors.

And, to choose which is best for you, you need to keep in mind what the base color you already have in your hair is.


If you’re starting with a very light base color:

  • 10 platinum blonde, you could use a 6 light brown.
  • 9 light blonde, you can go for a 5 medium brown.
  • 8 blonde, you can use a 4 brown.


If you have light or medium-colored hair:

  • 7 dark blonde, you can use a 4 brown.
  • 6 light brown, you can use a 3 dark brown.
  • 5 medium brown, you can use a 1 black.


 By using these colors, you can look like you have double the amount of hair and much thicker hair. And, best of all, all you need to do is buy a dye kit and follow the instructions it provides to a T.


Do you have thick hair and you want to make it seem thinner? Choose one of these colors

Light colors are ideal for women that have thick hair and a lot of it.

A lot of women come to my salon asking how they can thin their hair or if they can even just cut some of it out.

Unfortunately, you can’t, unless you want to cut your hair in layers to take away some of its volume or shorten your hair to get rid of some of its length.


 But if you don’t want to cut your hair, then my recommendation is that you dye your hair a lighter color. 

The lighter the color, the lighter and thinner your hair will look.


Just like in the previous case, the color dye you should choose depends on the base color you’re starting with.

And something very important that I want you to remember is that you don’t have to bleach your hair, you should just lighten your hair over time, lightening it 2-3 shades per dye job.


If your hair is mediumly dark:

  • 4 brown, you can use a light brown 6.
  • 5 medium brown, you can use a light brown 7.


If your hair is light:

  • 6 light brown, you can use an 8 blonde.
  • 7 dark blonde, you can use a light blonde 9.


 If you use any of these colors, keeping in mind your base color, your hair will look less voluminous, thinner and like you have less of it. 

That will give you a more fresh and youthful style.

Now, thin hair and thick hair require special care. Do you want to know what steps you should take? If so, keep reading.


How to take care of your hair depending on how thick it is


Taking care of thin hair

  • It’s easy to take care of thin hair if you have the right products. For example, you need to choose the right conditioner and use it correctly.

Thin hair usually gets greasy at the roots. To combat that,  you’ll need to minimize the amount of conditioner your use and focus it on your ends instead of at your roots. 


  • After you shower, keep in mind that wet hair is much more susceptible to breaking, especially thin hair.

To avoid breakage, get as much water out of your hair as you can, vigorously wringing it out, and avoid brushing your hair when it’s wet.



How to take care of thick hair

  • Thick hair also requires some special care, because it’s usually more prone to frizz.

And, if that weren’t enough, thick hair tends to dry out easier,  so it’s important to use products that keep your hair hydrated and help keep control over the frizz.  

Do you know what causes frizz?


The outside layer of your hair cuticle lifting causes frizz. Its lifting allows humidity in and that makes your hair frizz up.

When your hair cuticle is flat and not lifted, your hair stays soft and not frizzy.

Several things can cause frizz, but the most common for women with thick hair is having dry hair.


  • If that’s your case, your greatest allies will be hair oils, since they are key to keeping your hair nurtured and hydrated.
 You can use coconut, argan or almond oil. You should apply a few drops to your scalp and let it absorb.  


  • You can also opt for a keratin mask. Keratin is the most important protein in your hair, so if you use a keratin mask once a week, you’ll be able to keep your hair hydrated, especially the middle and ends of your hair.


  • And in terms of diet and nutrition, try to incorporate omega 3, which you can find in veggies and nuts, to add shine, minimize breakage and strengthen your hair follicles. And don’t forget to eat meats and fish that are rich in biotin and vitamins B6 and B12.


  • Last piece of advice! There are special products out there known as hair thickeners that you can find in shampoo, conditioner, cream and oil forms.

I very specifically do not recommend them since the results can vary widely between women. If you’re dead set on trying them, read the reviews online or ask a friend that you know has used one.



Now you know that this idea that dye thickens your hair is a myth.

But, best of all, you also learned which color dye you should choose if you have thick or thin hair, and how to take care of it to keep it healthy.

What do you want for your hair? Do you want it to be thicker or thinner?
