Does dying your hair damage it forever? Everything You Need To Know

So you’ve been dying your hair for some years now and suddenly you noticed your hair is not as healthy as it once was before you started playing with colors. And you’re wondering, what’s going on?

Or maybe you’re a newbie looking to pull off a look you saw in a celebrity magazine and you’re doing some online consultation to know the demerits of switching your hair color.

Does Dying Your Hair Damage It Forever?

No, dying your hair won’t damage it forever if you take the necessary precautions. For those who dye their hair for every event, and are now noticing some dull look on their hair, they can salvage the situation by going to a hair clinic and getting on some hair treatment plan.

The damage from coloring your hair usually comes from how often you dye it. So if you dye your hair a lot, you are more likely to get affected by harsh chemicals in the hair dye.

To help you understand this, I’m going to go into detail of what happens when you dye your hair.

What Happens When You Dye Your Hair

To strip away your natural color and allow the dye molecules to set in, your hair is exposed to several harsh chemicals that could cause serious damage over time.


To allow strip away your hair color for the new color pigments to set in, the hair dye has to first get through the cuticle

The cuticle is the hair’s natural protection and the first line of defense. Ammonia successfully breaks through the cuticle by making it swell. When that happens, the pigments of the new color can set in and a hair reaction can occur.


Bleach is a major ingredient in many hair dyes. When used in laundry, bleach wipes off stains from your clothes, when used in hair dyes it strips away your natural hair color to make room for the new pigment.

Before applying peroxide to your hair, hairstylists first determine the percentage that will be just right for your hair.

If you’re styling yourself, you may not know this which is why a lot of do-it-yourselfers end up with itchy scalp after coloring due to excessive use of hair dye chemicals.

Usually, the more peroxide, the more of your natural hair color it will strip away and the better the new color will look.

With your hair cuticle raised and your natural hair color out of the way, the pigments of the new color can now set in.

If you colored your hair with a permanent hair dye, the molecules of the dye will sit in the deepest layer of your hair. This is why permanent hair dyes barely wash out and only fade when your hair grows out.

For demi-permanent dyes, only just a few dye molecules penetrate the hair structure. Most of the dye molecules usually stay on the outside of the surface.

Semi-permanent dyes fade faster because the molecules don’t go inside at all. They only stay on the surface. That’s all on how you go from blonde to brunette with just one visit to the hair salon.

How Does Hair Dye Damage Your Hair

There are a lot of online sources stating that you could damage your hair by dying it, and several online sources claim that it could lead to hair loss.

None of that is false, your hair could become weak and brittle, but only if you’re a regular visitor to the hair salon. If you dye your hair more often than not, your hair is nothing short of a disaster waiting to happen.

All that ammonia, peroxide, and several other harsh chemicals that give you that stunning look that turns heads when you’re at an event or out to buy groceries could be your undoing.

Here are some things (hair damage related) that happen to your hair when you dye it

Texture Change

Immediately you lighten your hair, its texture will change forever but to some degree. The degree will depend on how well your hairstylist knows how to care for colored hair. If you’re coloring your hair at home, this might be the right time to stop doing so.

Reduced Elasticity

Along with a change in texture, your hair loses its elasticity every time you dye it. For people who color their hair very often, the results could be very drastic and easily noticeable.

Endeavor to do routine checks on your hair for changes inelastic. If you notice your hair is not as elastic as it once was, then you should stop coloring as you’re already on the path to irreparable hair damage.


Your cuticle is not just your hair’s natural protection, it also helps to keep moisture in so that your hair remains fresh and lubricated.

When you dye your hair, your cuticle is lifted and it will remain so for about 72 hours. This is why your hairstylist recommends that you wash your hair only after 72 hours to allow the hair cuticle to close so that you don’t wash off the new color.

But this also means that your hair will lose its moisture which leads to weak, dry, and brittle hair.

Prone to More Damaged

If you’ve already noticed a change in texture, elasticity, and continuous dryness, you may already have damaged hair. But it doesn’t end there. Your already damaged hair could be prone to more damage to more factors.

Think of it like the body’s immune system. When it is weakened by disease, it is unable to protect the body against future infections.

When your hair is damaged, more damage is likely to occur due to environmental factors like the UV rays of the sun and humidity
