How long does hair botox last? Aftercare to make it last longer

washing ruins the treatment

One of the questions I get asked the most is how long does botox last?


Botox can end up being quite expensive.

When people spend their money on a treatment, they want to be sure that their investment is going to last.

No one wants to spend a fortune on a treatment that only lasts 3 days.


The problem is, it’s impossible to say exactly how long the effects of botox will last.

Why is it impossible?

Because everyone’s hair is different.

Everyone’s hair is exposed to totally different life conditions and climates.


Hair of a person that lives in humid climates is not the same as hair of a person that lives in dry climates.

Hair that is washed everyday is not the same as hair that is washed every 3 days.

And I could keep going.

I think you get the idea.


For this, we have to sum up the characteristics of each person’s hair and the conditions that hair is in at the moment of applying the treatment. There is really greasy hair and really dry hair. Thin hair and thick hair.

On the other hand, the reach of the results will not be the same the hair of a person whose hair at the moment of applying the botox is in perfect conditions as one whose hair is mistreated and has split ends.


Suppose we have two people’s hair.

  • The first is a hair in perfect health. It is very well cared for with good quality hair products and not abused by heat instruments
  • The second is pretty stripped. It’s dry from constantly using flat irons and has split ends. From various kilometers away, you can see how damaged it is

These two types of hair belong to two friends of mine that decided to do botox on the same day at the same time.

In which person’s hair do you think the botox lasts longer?


In the FIRST.

Who should repeat the treatment?



Here, there are various questions that should be highlighted.

First, that the state of the hair at the moment of application is a determining factor.

The more damaged your hair, less time the effects will last.


Second, according to my experience, the hair that is already ruined probably will continue to be mistreated after the botox is applied. That’s why the effects last shorter time in this type of hair.

Now do you understand what I’m saying when I say that it’s impossible to determine the exact time the effects of botox will last?

No two people’s hair are the same.

That’s why it’s impossible to say how long the effects of botox will last.


And we haven’t even started to talk about the products that are used to do botox or the quality of application. It’s clear that you can’t get the same results from a generic product that you can from a name-brand one.

How long does botox last?

Having said everything from before and supposing that you use a good-quality botox, the application is done by a trained professional, and the hair is more or less healthy, botox can last about 6 months.


 The good news is that there are various things we can do to assure that the treatment lasts more time. 

A lot of times, simply changing shampoos or changing habits can make a huge difference for our hair.

So, now, we are going to see the very easy tricks to be sure the effects of botox last longer.




1- Use a Sulfate-free shampoo

Check shampoo on Amazon


One of the things that most affects the reach of the treatment are the products that we use for washing our hair.

All the products that we use to wash our hair are made with chemical ingredients.

One of the primary ingredients in most shampoos are sulfates (sodium sulfate).

The Joker.


What is hair botox worst enemy?



Sulfates destroys the treatment. It wears it away.

Sulfates is totally incompatible with hair botox.

What is the solution?


If you want your hair treatment to last longer, I recommend that you use a sulfate-free shampoo.


2- Wash your hair less often

Do you wash your hair every day?

If you wash your hair every day, the botox won’t last as long.


It’s very simple.


The more you wash your hair, the more the treatment wears off.

If you want your botox to last longer, you have to reduce the amount of times you wash it.


How often is ideal to wash your hair?

Every 2 or 3 days.


3- Avoid using hair dryers or flat irons

heat tools ruin the botox

One of the things that most affects the treatment is using flat irons and hair dryers.

Many people tell me, “But Carina, how am I going to stop using the flat iron? It’s impossible.”

or “Carina, if I don’t flat iron my hair, it will look awful.”

I understand all of this.


But you should know that the more you use the flat iron or the hair dryer, the less time your botox will last.

So that your botox last longer, I recommend that you use these tools as little as possible.
