But there has been a lot of fuss going on about its lawsuit story and potential side effects.

So the question is – does Olaplex cause hair loss?

Well, let's look at the following aspects:

  • how Olapex works
  • its side effects
  • Olaplex and hair loss
  • Olaplex's lawsuit

Note. This article is based on my own research on Olaplex Shampoo.

 Olaplex's Side Effects & Lawsuit (In A Nutshell)

Olaplex has been one of the most popular professional shampoos for hair repair. 

However, after Olaplex's lawsuit gained the attention of the media, you surely have many questions.

One of them is – “Can Olaplex cause hair loss?”

Well, it sure has its own set of advantages and drawbacks.

In short, some of the benefits of Olaplex include:

  • improves the strength of your hair
  • is designed to repair your hair
  • protects your hair from everyday stress (frizz, damage, split ends)
  • works for all hair types

What's more, some of its previous users said that they had satisfactory results.

This means that Olaplex might be a useful shampoo for your hair.

However, there is another side of the story.

In fact, not all its previous users had a positive experience with Olaplex.

Some of them, on the contrary, said that they experienced various side effects:

  • hair loss
  • dandruff
  • damaged hair
  • increase hair greasiness
  • dry hair or/and scalp

In fact, there are a few women who even sued Olaplex because of such side effects.

Those women claim that Olaplex products made their hair fall out severely.

However, Olaplex denies these accusations and declares that the products are safe.

So, based on these contradictory opinions, one cannot know for certain how good is Olaplex.

That's why, if you want to give it a try – make sure you know both sides of the story. 



How Olaplex Works 

First of all, let's see what type of shampoo is Olaplex.

Well, Olaplex is a professional shampoo designed to solve more of your hair problems.

As it claims to be professional, its price is higher than the price of a normal shampoo.

However, what are its benefits?:

  • protects your hair from everyday stress
  • this includes damaged hair, split ends, and frizz
  • promotes the health of your hair
  • makes your hair shinier

How does it do all those things?

Well, first of all, Olaplex has pretty good ingredients.

Moreover, its producers say that it uses a special mechanism of action.

In fact, the one responsible for that is Bis-Aminopropyl Diglycol Dimaleate.

What is this? It is a molecule present in Olaplex shampoo.

Actually, here's how this molecule works:

  • improves hair strength
  • protects your hair from within
  • provide immediate results
  • works for all hair types

What's more, Olaplex seems to be free of silicones and oils.

That's why it is said to be safe for everyday use. 

Is this actually true or are those exaggerations? We'll see that later on.

Yet, what is important to note is that Olaplex seems to have essential ingredients.

Here are just some of them:

  • Panthenol – retains hair moisture [1]
  • Helianthus Annuus Seed Oil – prevents hair breakage
  • Camellia Sinensis Seed Oil Ferment Extract Filtrate – moisturizes hair
  • Argania Spinosa Kernel Oil Ferment Filtrate – nourishes and protects [2]
  • Prunus Armeniaca Kernel Oil – reduces dryness
  • Helianthus Annuus Seed Extract – prevents dandruff
  • Euterpe Oleracea Fruit Extract – adds shine [3]

And the list can continue.

Whether or not this formula triggers side effects like hair loss, we will discover later.

For now, keep in mind its technology and that those ingredients seem to be useful.



Olaplex & Side Effects

The side effects of a product are some of the most important aspects to discuss.

So before choosing to use Olapex, we should talk about the side effects it triggers.

Only in this way will you be able to take an informed decision.

Now, what do its previous users say about Olaplex and its side effects?

Well, here the opinions are divided into two categories.

Some people say that Olaplex is an amazing product that made their hair stronger.

Among the benefits they mention are these:

  • hair feels soft
  • is easier to brush and style the hair after using Olaplex
  • even hairdressers recommend it

Based on these reviews, Olaplex seems like a pretty good product, right?

Moreover, as a professional product, it is used even in salons.

However, people did not write only positive reviews.

Some of them complained that they experienced various side effects.

Here are the most common ones:

  • intense hair loss
  • scalp sores
  • damaged hair
  • itchy scalp
  • dandruff
  • increased hair greasiness
  • dry hair and/or scalp

Well, those side effects are quite problematic, don't you think?

Especially because Olaplex might cause intense hair loss, as its users declare.

In fact, some of its previous users said that it made their hair visible thinner.

Not to talk about the other scalp problems it might cause – like itchiness or dandruff.

However, as in the case of other products, not all people experienced those side effects.

Thus, analyze carefully both perspectives before you try Olaplex.



Olaplex’s Hair Loss History

One of Olaplex's side effects people talk about is hair loss.

As I already mentioned, some of its users sustain that Olaplex made their hair fall out.

On the other hand, others say that Olaplex really helped their hair.

In fact, as Olaplex is such a popular product, it's pretty normal to have both positive and negative criticism.

Also, from what some of its previous users confessed, it might cause hair loss.

However, the number of people who said they experienced this side effect is not big:

  • around 30 women testified that Olaplex made their hair fall out
  • however, the company says that this is not true

Being on the market since 2014, Olaplex faces some negative reactions nowadays.

Based on the testimonies of its users, we can add hair loss to our list of side effects.

Thus it seems that even if Olaplex may cause hair loss, not many people will experience this.

Yet, hair loss is quite a serious problem, especially if we talk about a professional shampoo.

That's because it can have consequences like:

  • might cause a short self-esteem 
  • can lead to depression
  • affects your confidence

Since when have people started complaining that Olaplex causes hair loss?

Well, it seems that this has been an issue for a couple of years now…

Or at least this is what people say.

However, the problem gained the attention of the media pretty recently.

Why? Because there's a lawsuit going on regarding Olaplex's side effects.

We will talk about this in the next section so stay tuned. 



Olaplex’s Lawsuit

I'm sure that this is the subject you are most interested in, am I right?

So, let's dive into this discussion.

Olaplex's lawsuit is all over the internet and things are not clear yet.

However, how did such a popular product become involved in a lawsuit?

Well, let's see what happened:

  • 28 women sued Olapex for causing their hair to fall out
  • they say that Olaplex uses chemicals that damage your hair
  • Olaplex products should repair the hair, this is what it was designed for
  • yet, those women sustain that it left their hair and scalp in a worse condition

In fact, there is more to say about this.

The chemicals that those women refer to are lilial and panthenol.

Lilial had been used as a perfume for various types of cosmetics.

However, it was banned in March 2022 due to its impact on fertility.

According to some people's statements, Olaplex is still selling products that contain lilial.

How did Olaplex react to these accusations?:

  • they denied them
  • they said that Olaplex was proven to be safe for daily use
  • they sustained that probably those women experienced hair loss because of other causes
  • they said they removed lilial from their products

So things are more complicated than they seemed at first.

What's more, the women say that the Olaplex products alone are to blame for their hair loss.

That's because after they stopped using them, their hair conditions improved.

Thus, the question that remains is who is right?

Well, you will discover the answer to that question in the next section of the article.

Until then, keep in mind that Olaplex is quite a controversial product.



What’s The Truth Behind?

I'm sure you've been waiting for this moment for long.

So, what's the truth? Can Olaplex cause hair loss?

Well, my answer will disappoint you, I know that.

That's because there isn't a yes or no answer to this question.

As you've seen the opinions and reviews are divided into:

  • positive feedback
  • negative reviews

So we cannot know for sure whether or not it causes hair loss.

However, it is possible as there are people who said that they experienced such a side effect.

That's also the reason why I included it in the list of side effects.

Moreover, as it is a lawsuit going on, the answer will come with its result.

Should you use Olaplex?:

  • that's entirely up to you
  • yet, before that, make sure that you know all the information you need
  • I'm referring here to both the negative and positive comments

As you can see, Olaplex has both benefits and drawbacks.

That's why it is important to see both sides of the story before you take a decision.

So, what do you think? Is Olaplex worth trying?



Final Conclusion

To put it simply, Olaplex may be an effective shampoo for hair repair.

However, this coin has two sides – one is positive and the other is negative.

Moreover, there is one question that concerns people: does Olaplex cause hair loss?

Well, after analyzing the whole story, I can tell you that there is no clear answer to this question.

However, here are the advantages Olaplex seems to have:

  • protects your hair from everyday stress
  • improves hair strength 
  • promotes your hair health
  • prevents split ends and breakage 

On the other hand, Olaplex has its drawbacks.

Like any other product, it seems to cause various side effects.

So, based on its users' testimonies, these are some of the side effects it might trigger:

  • hair loss 
  • dandruff
  • itchy scalp
  • scalp sores

As you can see, its previous users sustain that Olaplex can cause hair loss.

However, its producers sustain the contrary, a dispute which led to a lawsuit.

Until this lawsuit has a verdict, one can't say with certainty whether or not Olplex causes hair loss.

So, if you want to give it a go, make sure you know its drawbacks.
