Bleach Hair and Keratin Treatment at The Same Time

You can do a keratin treatment and have your hair bleached at the same time. However, it is critical that you get your hair bleached first, then get the keratin, never the other way around.

Keratin treatments, also known as Brazillian blowouts, can increase the look and beauty of bleach blonde hair.

In this article, we will discuss the do’s and don’ts of the two options and explain what happens when you combine the two.

Should You Bleach Your Hair and Do a Keratin Treatment Simultaneously?

Professionals will tell you that bleaching your hair and doing a keratin treatment at the same time is a good idea since the bleaching process can put your hair in a good position to take well to the keratin process. 

Keratin treatments are used, for the most part, to treat frizzy hair that is prone to tangling and breaking.

The reason hair can become unruly is due to overly porous hair. 

Keratin fills in those pores to weigh down your hair and put some protein back, where it was lost to chemical treatments and age. 

Bleaching your hair does the exact opposite of a keratin treatment.

When you use bleaching or coloring products, you are making your hair more porous, which creates the issue the keratin treatment works to correct. 

Should you do Keratin Treatments Before or After Bleaching Your Hair?

Should you do Keratin Treatments Before or After Bleaching Your Hair

Most people who are looking to obtain these two hair treatments on the same day are probably trying to get it done with the least amount of damage to their hair as possible. 

For you to do that, you are absolutely going to want to bleach your hair before you go through with the keratin process. 

You should never, ever, get your hair bleached right after a Kertine treatment. 

It is suggested that you wait at least three months after the keratin is applied to your hair to go for the bleach. Why? 

The chemicals in bleach are really hard on your hair and can cause a lot of damage.

Damaged, dry hair is why you are getting the keratin in the first place. 

Bleaching your hair right after you go for a keratin treatment will decrease the effects of the process and won’t allow the keratin to set and become permanent. 

Can You Get Highlights After a Keratin Treatment?

Technically, yes, you can get highlights after a keratin treatment. However, it is definitely not recommended. 

The keratin treatment already puts your hair in a sensitive position while it is working its magic. 

If you were to add strong chemicals to the mix, you could damage your hair a lot worse than if you were to do these treatments separately.

If you want to get highlights and keratin treatment, you should space them apart for about 14 days. You can also get the highlights ahead of time and then not have to worry about the damage they cause after your protein treatment

The same goes for other hair manipulation such as heat styling. If you want to curl your hair after a keratin treatment or use straighteners, it’s definitely best to wait the full two weeks.

This is because keratin-treated hair is still malleable after the treatment and if you apply any heat, the keratin solution may not be as effective.

What About New Growth?

While it isn’t advised to bleach out hair freshly treated with keratin, you can bleach the roots if you are trying to keep up your color. 

While you don’t want to combine the chemicals with the proteins attaching to your hair follicles, it won’t bother your treatment or progress if you do the healthy, natural roots above. 

With that said, you should wait at least a few weeks before dying your roots to accommodate for the possibility of your color changing. 

Can Keratin Treatments Change the Color of Bleached Hair?

Can Keratin Treatments Change the Color of Bleached Hair

If you have bleached blonde hair, you might notice the color moving towards a darker blonde or even orangish. 

It is common for keratin treatments to change the color of bleached hair and the change won’t be instant. 

It may take a week or two for you to begin noticing your blonde hair is now an ashy, brassy, or orangy color.

This has to do with the way the hair cuticles are opened up and filled with nutrients, amino acids, and vitamins to strengthen and straighten damaged, frizzy, and unruly hair. 

Interestingly enough, keratin will not change the color of your natural hair. 

So if you go in without any dyes or chemically treated hair, you will leave with the same shade you went in with and will continue to rock that color until your next treatment.

However, even regular hair dye, semi-permanent, and temporary hair dye will lighten during a keratin treatment. 

How to Fix Bleached Hair Color Damaged by Keratin Treatments

Purple products are ideal for fixing the tone of bleached blonde hair, whether it is fading over time or your hair has gone through multiple processes, including keratin. 

You can choose a purple shampoo, mask, or other products that use a purple tone to counteract the yellowish, brassy color. 

If you are unsure what, purple shampoos are right for you, talk with your hairstylist or choose from one of the quality products listed below (available from Amazon).

Is Keratin Good for Bleached Hair?

Many professionals agree that keratin is a great treatment for people who frequently dye or bleach their hair. 

This is something you can do to correct some of the damage caused by the harsh chemicals that are well-known for drying out your locks and causing split ends and frizz.

If you bleach your hair and notice that it is starting to look dull, damaged, and frizzy, getting a professional, quality keratin treatment will help bring it back to life and give it back its shine.

While it may seem like a good idea to combine the two products and use them at the same time, it isn’t possible. 

Both of these treatments use some pretty strong chemicals that act in two completely different ways. 

If you tried to combine the products, it would be a huge mess and would cause more harm than good.

Frequently Asked Questions (FAQ)

How Often Can You Get a Keratin Treatment?

Technically you can have the treatment done roughly every 4-6 weeks. However, if you take good care of your hair and maintain it with the proper shampoos and products, you won’t need another round of keratin for up to six months.

Are Their Side Effects of Keratin and bleach Treatments?

Since both of these treatments require the use of strong chemicals, there is always the chance of an allergic reaction, skin irritation, burning of the scalp, etc. If you have allergies or sensitive skin, you should consult your doctor or, at the very least, the hairstylist with your concerns before undergoing any treatments. 

Can You Use Home Keratin Treatments on Bleached Hair?

There are quite a few home keratin hair masks, treatments, and shampoos that will work great at smoothing your hair out and reducing a little frizz. However, home treatments do not have the same ingredients as the products you find at a salon, which means they won’t last as long or work nearly as well.

Can You Use a Flat Iron on  Bleached Hair After a Keratin Treatment?

After your keratin treatment, it is advised you do not wash, add products to, or apply heat on your hair for at least three days. After this time, it is safe for you to go back to your regular styling routine, including flat irons, blow-dryers, and shampoos.
