Olaplex vs Keratin: Which One Should You Go For?

Sharing is caring!

There are many exceptional haircare brands launched over the years.

Gone are the days when you had to settle for your natural hair. Now, you can take advantage of various haircare products to achieve your desired hair quality.

If you are passionate about haircare, you should be familiar with Olaplex and Keratin.

These top haircare brands are among the best and most accessible in the market. If you’re unsure which to choose, this article will guide you.


Olaplex is an excellent haircare treatment option that utilizes high-quality ingredients to promote longer and glossier hair.

This treatment works by repairing damaged hair at the molecular level. Although the process is relatively slow, it is highly effective and ultimately rewarding.

Consequently, Olaplex is predominantly used by individuals with severely damaged hair.

So, if your hair has been damaged by curling irons or chemicals, consider using Olaplex to restore it.

Keratin is another haircare treatment that helps with damaged hair. However, it is best suited for mildly damaged hair, as it works externally.

This characteristic makes it much quicker than Olaplex.

Olaplex vs Keratin: Which Is Better?

Understanding the price of each treatment will inform your decision. Olaplex is a costly haircare treatment due to its molecular-level effectiveness.

Additionally, Olaplex is relatively difficult to find.

Unless you are determined, obtaining this treatment may be challenging.

Keratin, conversely, is a more affordable option. Although not as effective as Olaplex, it can still achieve satisfactory results.

Moreover, it is widely available and popular, making it the preferred choice for many.


To determine the appropriate hair treatment product, you need to understand their application process.

In simple terms, Olaplex has a more complex method of application.

When applying, you must use distilled water exclusively. Other water types will weaken the treatment’s effects.

Furthermore, if you want to add dye, mix it with Olaplex before application. Failing to do so may result in a poor outcome.

On the other hand, Keratin has a straightforward application process. You can easily apply it during your standard bath.

Suitability for Hair Types

When choosing between Olaplex and Keratin, consider your hair type.

Olaplex is suitable for all hair types, including colored and chemically-treated hair.

It is particularly beneficial for those with severely damaged hair due to its restorative properties.

Keratin treatments work best for individuals with frizzy, curly, or wavy hair.

These treatments help smooth hair, control frizz, and make hair more manageable.

Keep in mind that Keratin treatments may not be ideal for extremely damaged hair or hair that has undergone multiple chemical treatments.

Maintenance and Longevity

Another factor to consider is the maintenance and longevity of each treatment.

Olaplex is a bond-building treatment, meaning it repairs broken hair bonds and strengthens hair over time.

The results of Olaplex treatments can last for several weeks or even months, depending on hair type and follow-up care.

Keratin treatments, on the other hand, typically last 2-4 months, depending on the specific treatment, hair type, and maintenance.

It is essential to use sulfate-free shampoos and conditioners to prolong the effects of the treatment.

Ingredients and Mechanism of Action

Olaplex contains a patented ingredient called bis-aminopropyl diglycol dimaleate.

This active ingredient works by rebuilding broken disulfide bonds in the hair, which can be damaged due to heat, chemical treatments, or mechanical stress.

By repairing these bonds, Olaplex restores the hair’s strength, structure, and integrity.

Keratin treatments, on the other hand, work by infusing the hair with keratin proteins.

Keratin is a naturally occurring protein found in hair, nails, and skin.

During a Keratin treatment, the hair is coated with a keratin solution that fills in gaps and porous areas, creating a smoother and more uniform hair structure.

In-Salon vs. At-Home Treatments

Olaplex offers a range of products for both in-salon and at-home use.

The most potent Olaplex treatment, No.1 Bond Multiplier, and No. 2 Bond Perfector are typically applied by a professional hairstylist during a salon visit.

However, Olaplex also provides at-home treatments like No.3 Hair Perfector, No.4 Bond Maintenance Shampoo, and No.5 Bond Maintenance Conditioner.

All of which help maintain and prolong the results of in-salon treatments.

Keratin treatments are traditionally performed in salons by professional hairstylists.

However, some brands now offer at-home keratin treatments, which may not be as potent or long-lasting as salon treatments but can provide temporary smoothing effects.

Frequency of Treatments

Olaplex treatments can be used more frequently than Keratin treatments, as they focus on repairing hair bonds and can be incorporated into regular hair care routines.

Olaplex in-salon treatments can be performed during every salon visit, while at-home treatments can be used weekly or as needed.

Keratin treatments, due to their more intensive nature, are typically performed less frequently.

Depending on the specific treatment and individual hair type, Keratin treatments may be repeated every 2-4 months or when the results begin to fade.

Effects on Hair Texture

Olaplex treatments primarily focus on hair repair and do not alter hair’s natural texture.

After an Olaplex treatment, your hair will feel stronger, healthier, and more resilient, but its natural curl or wave pattern will remain intact.

Keratin treatments are designed to smooth hair and reduce frizz, which can lead to a noticeable change in hair texture.

For those with curly or wavy hair, a Keratin treatment may result in looser curls or waves and a more manageable texture.

Before making a decision, consider factors such as price, performance, hair type, and desired results.

Ultimately, it is about selecting the hair product that best suits your needs.
