Any hair stylist or at-home keratin expert will tell you that you need to wait at least two weeks before coloring your hair. If you dye your hair immediately after a hair therapy, then you won’t get the full results. When you dye it less than two weeks after your keratin treatment, your hair color could look patchy because your hair strands would not take at all.

This is because the keratin applied on your hair has coated your strands, making it more difficult for colorants to penetrate into it and work their magic. But, I can assure you that you will not be happy with the results of your coloring should you decide to do so immediately after a keratin therapy.

It’s always recommended to color your hair before having a keratin product applied to it, rather than after.

What is Keratin?

Keratin is a natural protein found in the body. It makes up everything from your nails to hair and is designed to help keep them strong and healthy. For hair, keratin encourages the strands to grow longer and thicker. This gives your scalp a fuller look. It also helps to brighten up your hair to give it a stunning and luxurious appearance. 

Is Keratin Treatment Safe for Hair?

Keratin treatment is generally safe to use on hair. However, you need to be careful to check the ingredients in them. Sometimes keratin products contain harmful chemicals in them, including formaldehyde. A few might also burn your strands giving them a damaged appearance. 

Because of this, it’s important to carefully research the type of keratin treatment you plan to use. 

Types of Keratin Hair Treatments

There are plenty of keratin hair treatments available. However, the right one to use will depend on a few things. These include how natural you want the treatment to be and the type of hair you have. 


This keratin treatment tends to be the most natural option. It uses less toxic chemicals, like formaldehyde, and is ideal for those who want a quick touch-up. Keep in mind that this treatment needs to be kept longer in your hair than others. 

Keratin Complex

If you have medium to thick hair, this treatment is best. It will leave your hair extremely soft and is also low in toxic ingredients. The one downside is that it doesn’t tend to last very long. 

Goldwell Kerasilk

This is a powerful keratin option that incorporates silk into its formula for top results. By doing so, it improves your hair’s health and prevents skin irritation. This keratin treatment can last for up to six weeks. 

Trissola Plus

Trissola Plus is the strongest type of keratin treatment available. It’s best for those who have damaged hair or whose hair tends to frizz. Because of power, a Trissola Plus treatment lasts longer than the other options. 

If you visit a hair stylist, they might create a unique formula specifically for your needs. This might involve mixing a few different keratin treatments together for extra benefits. 

Why Should I Color My Hair Before Keratin Treatment?

It’s often recommended that you color your hair before you get a keratin treatment done. This will allow the color time to soak into your follicles. It will also prevent the keratin from altering the color treatment. You’ll find that by doing so, it will help your hair’s color last longer because the keratin acts as a sealant. 

How Long Do I Need to Wait to Color My Hair After Keratin Treatment?

As mentioned above, you’ll need to wait about two weeks to color your hair after your keratin treatment. This ensures that the keratin treatment has fully absorbed into your follicles. 

If you don’t wait for this amount of time, you’ll find that it will be harder for the color to coat your hair. This will end up giving your mane a dull and patchy look.

Highlights After Keratin Treatment

As with coloring your hair, highlights should be avoided immediately after a keratin treatment. Depending on the color of your highlights, they’ll either not take at all or come out looking more like spots.

Decide on a plan for your highlights before having your hair therapy done. You can even do them right before your treatment.


But again, if you want to add color to your hair after treatment, even if it’s just in the form of highlights, you should wait at least two weeks before doing so.

Keratin or Highlights First, Which Is Best?

The answer to this question will always be applying highlights first. As I’ve already mentioned, adding highlights right after a keratin treatment will not give you the results you want. In fact, having your highlights applied first has its own list of benefits.

If you highlight your hair right before your treatment, you’ll actually be extending the life of your streaks. This is because the keratin procedure will help seal the color in, making it more of a permanent change rather than a temporary one. Also, you can expect your highlights to look more vibrant when done before a procedure.

But if you forgot to schedule a highlight appointment before your keratin treatment, you can still get the results you want as long as you wait at least two weeks.

Most keratin therapies last at least three months so it doesn’t hurt to wait a little longer. The longer you wait, the better your highlights will look.

But if you want highlights that look like they belong on the red carpet, having them added before your procedure is ideal.

Bleaching Hair After Keratin Treatment

Can you color hair after a keratin treatment?

We know the answer is after a few weeks. But something you should never do is bleach your hair after a treatment. Going lighter almost guarantees that you’ll be stuck with patches, which is not a good look for bleaching.

There’s really no way around this. If you really want to bleach your hair after a keratin therapy, you’re just going to have to practice patience. While you should wait two weeks before coloring or highlighting your hair, for bleaching, you’re going to have to wait until the effects of your hair treatment are no longer noticeable.

If you’re stubborn, don’t attempt to bleach your hair yourself. Go to a salon so they can prevent serious discoloration and potential damage.

Hair Toner After Keratin Treatment

Here’s where you get a pass. It’s normal for your hair to turn a bit brassy after a keratin treatment, especially if your hair is on the lighter side. To combat this, use purple shampoo. This will get rid of the yellow undertones in your hair.

While you need to wait at least two weeks for other treatments after administering keratin, you can use a toning shampoo right away. Just remember that you can’t get your hair wet for a full 48 hours after your hair therapy. But after this window, you should be good to go. Use the shampoo once a week until you see the results you’re after.

So can you color hair after a keratin treatment? If you’re still not sure, speak to a stylist. They’ll be able to help you get the results you want without ruining your treatment or hair.

Just remember that in most cases, you’ll need to have plenty of patience. If you want to learn more about how to properly apply an at-home keratin treatment, click here.
