Does keratin change your hair color? Can it darken it or lighten it?

Smoothing changes the dyed hair color

Keratin treatment can lighten your dye color one or two tones, if the color you have is between light brown to yellow. In black and red, the change is barely noticeable.

That is, the straightener treatment will darken the color of the dye, and if it lightens, it will depend on the tone of your hair.

Now, if you don’t want your color to change, it’s important that you respect the order in which the two procedures are applied to your hair.

If your hair color is natural, meaning you have never applied the dye to your hair, the color will not change. Dark brown will continue to be dark brown; blond hair will continue to be blond.  

If you use keratin properly, your hair color will not change and you will get the best effect of this treatment, which is a real miracle for your hair.

When I tell you this, I remember Elena’s case.

Elena is one of my clients, one of whom is always very proud of their hair.

And the truth is she has her reasons. Her hair is long with light waves that looks more like a waterfall than a mane.

 The problem is that Elena gets tired of using iron to straighten her hair. On average, she has to wash her hair, dry it with a hairdryer every day and plan to use iron for an hour.  

It was tiring, not only because flattening such long hair could be quite a feat, but also because she slept less than it needed. And this has caused her problems in everyday life.

She has difficulty concentrating on studying, forgetting about important things in work, she feels more tired.

That is why, a month ago, she came to do a curiosity treatment. After evaluating her hair, it seemed to me to be a good choice.

The first is that her hair is dry and damaged from the use of heat tools. And second, because she won’t have to get up two hours earlier to straighten her hair.

Her hair has become precious. You could say that keratin is done. Don’t forget that it’s a protein, capable of filling hair strands, giving hair nourishment and moisture.

Continuous use of flat irons and hair dryers will remove the natural proteins present in the hair. That’s why your hair is unstable and weak, and frizz occurs.

Can you imagine what your hair would look like under a microscope?

To give you an idea, your hair might look like a road with cracks and cracks or a piece of limestone with tiny holes.

So, Elena left my salon enthusiastically, happily, and happily that day.

But that happiness lasted about five days.

 Because when she returned to the salon after five days, her hair… I don’t know how to explain… a dull, dull brown, but worst of all, there were stains all over her body. 

When I asked what happened, she told me that she applied dye, the kind of dye she used every time she dyed her hair. She used the same brand and left it in place for the same time.

My eyes leapt out of the sockets. Yes, just like in the cartoon. I can not believe it!

How could she even think about applying hair dye four days after applying keratin!

I don’t want to be tough, but sometimes I think that when stylists do these types of treatments, there are some variations that go beyond the hair. It’s as if nerve cells have been replaced by little birds.

Would you like to know what happened to Elena’s hair and why the keratin changed the color of the dye?

Then don’t move, because I will tell you:

  • Why keratin can alter your dye color and how to prevent it
  • How keratin works with the natural color of hair

Now you will have no reason to spoil your hair color with keratin.

How to prevent keratin from lightening your dyed hair color

I still can’t get past Elena’s desperate and scared expression.

Oh my God! Why didn’t she send me a WhatsApp to ask me if she could dye her hair?

She will avoid the horror that her hair is over.

And most importantly, she will not throw away more than one hundred and fifty dollars that she spent on treatment and after dyeing.

This is very simple.

To prevent the keratin from hindering or lightening the dye, you should apply it for at least fifteen days after straightening your hair.

The explanation is very simple.

Keratin forms a light layer on the hair and the chemical products present in the dye do not penetrate this layer properly.

That’s why your hair may turn a different color and even look dyed.

 Therefore, it is important that you dye your hair fifteen days after the date of keratin

Now, if you have dyed your hair blond, for example and you have straightener therapy, chances are you will have some blond hair. But don’t worry, as this yellow will fade in the first wash.

Brunettes and redheads are best, as the keratin will not change the color of their dye.

There is also another possibility when it comes to keratin and coloring.

Have you ever seen that keratin can color and condition your hair after dyeing ?

To do this, you only need to dye your hair ten days before the straightener. In this way, keratin seals in the dye pigments while restoring your hair’s natural moisture.

Now, what happens to the keratin in undyed hair?

In natural hair, keratin does not lighten or darken hair. Because there are no chemical colorants that can interfere.

Conclusion on color and keratin

As you can see, keratin and hair dye are the two pathways that in most cases go through.

In Elena’s case, we waited for about fifteen days and reapplied. Since she didn’t want to take any risks, she did it at the salon.

And then, she had the same smile as when she straightened her hair.

That’s why if you dye your hair and apply keratin, always remember:

  • If your hair is dyed between the gamma of light brown and blond, the color can lighten one or two tones.
  • If your hair is dyed black or red, the dye will not fade.
  • If you haven’t dyed your hair yet, you have two options: apply it ten days before straightening or dye fifteen days after keratin.

In the end, keratin never lightens or darkens your natural hair color.

Leave-in conditioner for keratin treated hair or straightened hair

using conditioner

Today, I want to tell you why it is important for you to use a hair conditioner if you have been on keratin treatment.

But first, let me tell you how I discovered this incredible product because I’m sure you’ll identify with me.

My life completely changed when a few months ago, I went for keratosis treatment.

It is unbelievable what a hair treatment can do.

In my case, I spent two hours every morning in the bathroom, straightening my hair for the perfect haircut. I’m the executive secretary and my looks are key.

 Also, thanks to keratin, I have been able to remove frizzy hair so it looks healthy and shiny.  

But about fifteen days ago, I started noticing a few changes in my hair.

At first I thought it was just in my head, but after the alarm rang in my head.

Curls slowly began to emerge from the darkest depths and although the straightness was still not over yet, I still had to use the flat iron to make it fully straight.

What happened?

I have followed all of my stylist’s advice.

I didn’t wash my hair in the first 48 hours, I didn’t pull my hair in a ponytail or behind my ears, and I hadn’t even jumped into the pool.

 The only thing I can’t do is wash my hair less often. I continue to wash my hair on average every day, or at most every two days.  

I have very greasy hair, and if I don’t wash it frequently, it looks dirty. And I couldn’t give that impression at work.

I desperately called my cousin, Fernanda, who is an expert in keratin treatments. She almost shrieked to high heavens when I told her how often I washed my hair.

When I explained that I washed it that frequently to avoid greasiness, she said three words, well five actually: you should use leave-in conditioner.

Althought I was a bit skeptical, I followed her advice.

And it was my salvation and the salvation of my straightening treatment.

 Are you in the same situation? Do you notice that your keratin is fading quicker than it should?  

There are two paths you can follow.

The first, continue with your normal routine and risk becoming a slave to your flat iron.

Second, combine the residual conditioner in the hair to protect the keratin process.

what do you say?

Very well, if you chose the second option, you are on the right track.

That’s why, today I’m going to tell you:

  • These three balms are best for straightening or keratin-treated hair
  • How to apply conditioner to hair

Have you done the keratosis treatment? Use one of these three conditioners

There are many types of conditioner on the market. That is why I do not want to waste any important time and time to prevent the horns from going away.

That’s why, I let my cousin, the chemist with chemical straighteners , give me her opinion on which is best to use.

She has straightened her hair for three years, so I think she has something close to a PhD. on the topic.

In addition to straightening your hair, do you dye your hair?

Then I recommend this conditioner as it is the one my cousin uses, as her hair is horny and has also been dyed.

Elvive Total Repair 5, L’Oréal Paris

damaged hair due to treatment

My cousin has fairly long, waist-length hair, so she often has to protect her hair from breaking and split ends .

Keratin helped her re-connect broken hair, but she found it lacking moisture and softness.

So, once a week, she uses this conditioner to keep her hair moisturizing, making her hair look shiny and softer to the touch.

Do you have oily hair?

You are like me! That is why this conditioner is best for you.

Fluidissime Spray, Kérastase Discipline

Ideal for keratin straightening hair

I don’t have dyed hair, but it’s very greasy. And I washed it too often so it looks clean. And that made me fall into a vicious circle: more grease – wash – grease.

With this conditioner, I was able to control oily and make hair look cleaner even though I didn’t wash it.

If you have greasy hair , I highly recommend this glue as it is a spray and does not have a creamy consistency, it is a less oily product. And we want to avoid the greasy feeling other products can give us.

Remember I told you I noticed a little freaking out?

I forgot that when I started using this product.

Since my cousin always has tricks, she also introduced a non-conditioner conditioner for all hair types.

Smooth Blow Dry Anti-Frizz Cream, Garnier Fructis Style

Brazilian or Japanese straightening

This conditioner is ideal for people living in wet or rainy climates, as your hair will be protected from excess moisture.

Because we know that that is the cause of the frizz.

Do you use a hair dryer every day ?

Then don’t turn your back on this product, as it also acts as an excellent heat protector.

Now that you know which conditioner is best, I’ll show you how to use them properly.

How to use conditioner properly

You should always use it after your normal washing routine on wet hair.

Apply a small amount, focusing mainly on the ends of your hair and areas where your hair feels more dry or curly.

Since I use the spray, when I get out of the bathroom, I dry my hair with a towel without twisting it. The idea is simply to squeeze out the water.

 I applied 4 to 6 sprays, waited about 10 seconds, then I just removed and brushed my hair.  

Conditioner contains moisturizers often helps moisturize and soften the hair , making hair strong and smoother.

I am very thankful to my cousin for helping me cure keratin from extinction. Because Since I have been using this balm, I have been able to prevent the appearance of curly hair and the waves from starting to appear.

Which of these three conditioner do you think is best for you?

Remember when you got your fixed?

  • Perm and neutralizing solution
  • Shampoo and conditioner
  • Comb or brush

Step one:

  • Wet your hair and then separate it into different parts to distribute the curling solution evenly.
  • Apply the solution to each part of straight combed hair.
  • Allow the solution to soak in the hair according to the manufacturer’s instructions and wash off consciously. You should completely remove the solution before using the neutralizer.
  • Apply neutralizer and let stand according to the product’s instructions.

One thing is clear, never repeat with permutations! At least for me.

In the end, what do you decide?

Will you remove natural perms or use chemicals?

Do people still do perms? Types of Modern Perms

everyday hair treatments

I am still laughing at the face my client had today when I suggested that she do a hair curler.

She looked very scared as if I was asking her to shave her hair completely.

When she got past the first bounce, I explained that the edits made today have nothing to do with the eighties, looking like little screws in your hair.

Perms have evolved a lot over time, and yes, in the end, people still do perms.

Because the hair industry has come up with different curling systems, so that each woman can have different curls, and even give the hairline volume or just the ends.

 That’s why the perms are constantly updating. You just have to decide what effect you want on your hair to choose a curling style that suits you.  

In case you didn’t know, curling is a process where hair is chemically treated to change their structure and obtain curls.

This curling effect on hair can be achieved with different systems, like cold or hot curling is also known as digital.

Would you like to know who was the first to experiment with curling in their hair?

I will give you some tips.

  • It’s a town where a queen worries too much about their beauty treatments
  • They built large tombs called pyramids.
  • They sailed on the feluccas


The Egyptians were the first to develop a long history. They curl their hair around the stick, covered with clay, and finally sun-dried.

Years will pass, exactly in 1905, when Karl Nessler invented a dryer using sodium hydroxide, the brass bars he heated to 212 ° C.

In this case, this process takes six hours, as opposed to the one and a half hours that today can take to perform a permutation.

For now, the permutation process implies using two main components.

The first part is when wrapping the hair around the stick and applying curling solution to change the structure of the hair.

The second part implies using the neutralizer to define curls.

The type of curler you will receive depends on the size and shape of the bars used, the technique used to wrap it, and the type of curling solution applied.

 What are the types of perms used most today? 

After that, keep reading, as the curls are in curls, and you have to choose which permanent curl you want to make you laugh from ear to ear.

Also, I’ll let you know what kind of permanent I did in the end for my client.

Modern Right Types: Choose what’s best for your style

today they incorporate modern technology

Like I told you before, the type of curling will depend on the type of rod or curler you use.

But there’s another factor, too, and that’s the type of fixed solution you use.

The solution can be acidic or alkaline.

  • Curls performed with an acid solution are softer in the hair and create smoother, softer curls.
  • Alkaline curls are better for thicker hair with lower elasticity and more durable curls.

Having made that difference, we can now dive into the fascinating and present world of perms.

Spiral Perm

lasted six months

Spiral helices are tightly curled curls that look like corkscrews, and they will always depend on the size of the bar, the type of curling solution used, as well as the stylist’s experience.

 The end result is a waterfall of curls with curl and bounce. If you want top volume, this is the best option for you.  

Another thing to keep in mind is that this curls last about six months, after which, the curls will begin to fall out.

Perm ripples

Ideal for beautiful hair

Do you have very thin hair? Then this is the option for you.

Because without such a tight curl, you get more volume and body in your hairstyle. The end result is large curls achieved with the help of large curling rods.

Plugs in on time

Have you noticed that in some parts of your hair you have bald spots? Or maybe you have natural curls, but are they uneven?

This curler will allow you to cover those bald spots, as you only apply the curling solution at those points, allowing you to cover those gaps.

The same goes for when you notice that on one side of your head, your curls are more defined. A stylist can combine both parts of your hair.

Clinging to the roots

If you get tired of using original products to increase volume then this is the ideal solution for you.

Root curlers will prevent you from having to deal with all the hair for volume. Now, the tricky thing is when your roots grow.

So you will most likely have to go through the process every two months .

I recommend looking for a good stylist to curl your hair, because it’s important to have a specialist who doesn’t let the curling solution stay on your hair.

Swap multi-textured

Personally, I recommend this perm for those with long hair.

And when I say long, I mean about 10cm long hair over my shoulders.

Do you want to know why?

Because the length of the hair allows you to play with different sizes of curls that fall to the other end, giving a super natural look with less defined curls.

Part Perm

While you may not believe it, for now, you can only apply curling to certain parts of your hair.

Essentially, it’s a curl for women who want to give bodies and movements to their hair.

Unlike root curling, partial perm is applied to the entire head, not the entire hair.

Perm at the end

The name of this says it all. With this curl, you add only curls to the ends of the hair. Best for those who want more fluffy hair.


These are perks that are trending, and as you can see, each includes different needs and preferences.

 It is important, as always, that before you decide what type of bending machine you want, you should consult a specialist.  

After all, curling is a process that uses quite powerful chemicals that can change the structure of your hair.

Additionally, a stylist can recommend which curling style best suits your face shape, like the type of effect you desire.

That’s what happened in the case of my client.

She is looking for a cut that will bring her more episodes. But her hair is long and beautiful, so what’s wrong with cutting it off.

So I proposed a partial permutation.

When I finished and asked her to look in the mirror, her face said it all: she was fascinated. Because she can maintain the length of her hair, but her hair now has volume and it even has a distinct look to it, I’d say almost barbaric.

Now you know that the perms are still fashionable, but they have changed a lot from the ones made in the 80s and 90s.

What about you, what are you going to choose?

Should you wash your hair before a perm? What shampoo should you use?

for not washing your hair first

Before bending, it is very important that you wash your hair with a neutral shampoo. If you don’t wash your hair, you run the risk of the perms ending up badly.

How do I know?

Because my cousin did an experiment two months ago and the result was catastrophic.

At the salon where she went, they didn’t wash her hair first. And that’s a big mistake.

 Some people think that you should never wash your hair before curling your hair because that way you protect your scalp and hair from the harmful effects of chemical products. 

When you don’t wash your hair, your scalp produces natural oils that function to protect the hair.

But what you don’t know is that those oils also prevent chemical products used in the curling from entering the hair shaft and changing the molecular structure of the hair.

After all, it is permutation.

During the curling process, chemicals are used to temporarily break down the bonds in your hair strands and allow the reconstruction of those bonds.

That’s what gives your hair a new curly look. Once you break those bonds, the hair will be remodeled and curled using a hot strip and roller.

 You can’t imagine the scared face my cousin had when she was finished and she had less curls than anything in her hair.  

Apparently, she protested loudly, almost screaming and threatening with legal action until they returned the money to her.

But they rejected her desire to experience a similar experience again. And finally, she gave up on founding part of the curly-haired women community.

If you don’t want the same thing to happen to you, keep reading because today I’m going to tell you:

  • How to wash hair before curling hair
  • Take other preliminary care before performing curling

So there are two paths: be fully informed before doing treatment, because after all, you never know what type of stylist you’ll be looking for.

Or get notified and end up like my cousin, utterly disappointed.

What do you choose?

How to wash hair before curling hair

Whether you decide to leave your curls permanently at the salon or at home, the previous steps are the same.

Now, if my opinion interests you, I recommend doing it at the salon. After all, you must use chemical products that should be handled by specialists.

So let’s start washing.

This is the basic first step before getting started with permutation.

 Have you stopped to think about all the debris that builds up on your head throughout the day?  

Many things, things that most people cannot see at first sight.

Like dust and dirt. Everything you find in the environment and stay in your mind.

But also, when we wash our hair and condition our hair, residue is still left over from the products we often use.

Residue accumulates on the outer layers of the hair.

And that doesn’t go away with regular shampoo.

 They are removed with neutral shampoos, also known as pH balanced shampoos

I don’t want to make you dizzy. After all, what you want is simply to have some nice curls in your hair.

This shampoo is mildly acidic, ensuring pH balance.

This allows it to remove residue from the hair without losing the natural oils.

That way, chemicals that interfere with the curling can get into the hair cuticle to change internal structure.

It is also not necessary to take a course.

Use this neutral shampoo as you would a regular shampoo, but remember to rinse your hair thoroughly.

After you’ve washed and rinsed your hair, move on to step two.

Let me ask you a question.

Should you dry your hair with a hairdryer before applying curling liquid?

Certainly not!

You should just remove excess moisture with a towel, do nothing more.

And then, you’ll be ready to split your hair into sections, applying the roll of your choice and the curling solution.

For now, it’s important to keep in mind other considerations before you do the permutation.

Other preliminary considerations before performing permutation

As I mentioned before, the permutation process involves chemical products. That’s why it is important for your hair to be healthy before applying it.

  • Avoid dyeing your hair for at least two months before applying permanent curls.

The dye also contains chemicals like hydrogen peroxide that weaken hair and even break it off.

  • Two days before perm, I recommend deep conditioning.

It is not necessary to spend a fortune at a beauty salon.

You can choose between two absolutely great products and I’m sure one of them you have at home.

It involves olive oil. Apply enough to your hair and let it sit for at least 30 minutes, even overnight .

The other product is coconut oil, which you should use in the same way as olive oil.

  • And what will happen to your split ends? Is it best to cut them before or after doing the bending?

Of course, you should get rid of them.

What I recommend is you cut them after curling, because as you can imagine, the curls will change the length of your hair.

The best thing is to cut them when you can see the final length of hair after the curls have formed permanently.

Finally, after the curling finishes, don’t wash it for 48 hours , that way you will be assured that the curling solution does its job well.

Now you know how to properly wash your hair before curling your hair.
