K18 Peptide Hair Treatment: Is There Anything Better than Olaplex?

July 1, 2021

Rachael Grant

I decided to use k18 Peptide, and it was the best decision I ever made. Here is why!

When Olaplex hit the shelves back in 2014, I was one of the first stylists to embrace this innovative product wholeheartedly. Within months I no longer had to worry about colour damage, frizziness, and sun hair damage.

But with all its benefits. I also noticed some issues about the product that all stylists should know.

Things You Should Know About Olaplex...

One, Olaplex treatment is slow, meaning your client will have to sit at the washing bowl for longer. That is not only problematic to workflow, but it can also make your client uncomfortable.

Two, Olaplex treatment is cumulative. Meaning, your client may have to come back for treatment multiple times.

 Three, although I never experienced this, I have noticed several users complain about a red rash or burning and itching sensation ten minutes after using Olaplex. Have you experienced that? Tell us in the comments.

These drawbacks prompted me to ask myself one question, is there anything better than Olaplex? And could the answer be K18Peptide?

My answer to the question; Why is K18Peptide the perfect alternative to Olaplex? is One. you get instant results after one use. Two. K18Peptide treatment does not take too long (4minutes max). But that is just the tip.


Here is everything you need to know about K18Peptide and Olaplex to help you decide which product best suits you!

How is K18 Different from Olaplex?

Ten years of scientific research resulted in a product that, unlike traditional bond builders that temporarily strengthen hair, repairs and restores hair naturally and for longer. They named that product K18Peptide. Simplified, the science behind the product is the application of keratin genomics makes hair repair possible. Or, in other words, K18 contains 18 amino acids that work together to repair and reconnect keratin. Keratin is a protein that makes up your nails, hair, and skin.

The result of K18 treatment (single use) is improved elasticity, hair integrity, and shine.

And the best part is, you see the results almost immediately and without using too much product.

Olaplex is a standard bond builder that works on a molecular level to restore broken bonds. Unlike K18, using Olaplex is a three-step process that will improve hair strength and protect your hair from within. That makes the product perfect for home use, but inconvenient for a busy work setting.

Does k18peptide work?

Users report K18Peptide works in just four minutes. That means within four minutes of using the product, you will notice thicker, silkier, and softer hair. However, like all products, usage dictates the results. So, we must ask.

How do you use k18peptide to get the best result?

How to apply k18peptide mask

The process takes about eight minutes -broken down into two sections.

Step 1: make your hair damp (do not saturate).

Step 2: spray K18 Peptide in sections.

Step 3: wait four minutes.

Step 1: Shampoo the hair.

Step 2: Apply mask.

Step 3: wait four minutes.

Does Olaplex work?

As mentioned, Olaplex works. The only downside is it takes a little longer to see the results.

Depending on the severity of the hair damage, we recommend professional Olaplex treatment at least two to three times a month. Also, Olaplex No. 1 and Olaplex No. 2 are for professional use only.

So, if you are trying out the product for the first time on your own, use No 3. And no, you do not have to use No.1 and No. 2 to use number 3. Convoluted, right? 

The best option though is to purchase an Olaplex kit, this will ensure you have everything you need!

How to apply Olaplex No 3

Olaplex usage depends on the condition of your hair. That means the more damaged your hair is, the more you should use it. We recommend:

  • Use once per week for normal hair.
  • Two to three times a week for damaged hair.

Step 1: make your hair damp.

Step 2: towel dry.

Step 3: section and saturate hair with Olaplex No 3.

Step 4: wait at least 12 minutes or more.

Step 5: Wash and condition hair.

K18Peptide Before and After

Soft hair without a conditioner or thick mask sounds outlandish, but with k18Peptide it is possible in just four minutes. This product breathes life into dyed or damaged hair, and the best part is you do not have to rinse it out.

The product works, as mentioned, by transporting amino acids into hair shafts to help repair and strengthen hair.

That said.

When to use k18peptide?

The sun, water, products, and other factors contribute to ongoing hair damage. What that means is the longer you stay without treatment, the more damaged and lifeless your hair will look.

K18 is a product scientifically formulated to reverse and prevent hair damage. Thus, it works on all hair types. Consequently, we recommend you use it once or twice a week depending on the condition of your hair?

Some questions to ask yourself before using k18 peptide are?

  • Does your hair feel like straw brittles because you colour it too often?
  • Do you have split ends and dull-looking hair?
  • Do sections of your hair snap off easily under tension?
  • Does your hair feel smooth all the way down?

If your hair does not feel smooth all the way down or if you notice uneven surface, tension, and so on. It means that your hair is damaged. Therefore, use k18peptide to bring your hair back to life.

K18 FAQs

Can I use k18 on Healthy Hair?

K18 is a product formulated to bring your hair back to its virgin state, what that means is you may use it on both normal and damaged hair.

Should I Stop Using Conditioner?

Although k18 makes your hair look and feel “new”, that does not mean that it is a conditioner replacement. The purpose of the product is to strengthen and repair your hair and improve elasticity.

Conditioners are products formulated to make your hair softer and easier to manage. So, no, do not stop using conditioner. Instead, the idea is to use the product as described above, wait at least four minutes. Then apply a conditioner if you decide to.

Should I Clean my Hair Before Applying k18?

It is advisable to clean and towel dry your hair before applying k18peptide because of product build-up. What happens when you apply the product without cleaning your hair is. Film formers, oils or silicones left by other products act as barriers. This makes it harder for k18Peptide to reach and repair your hair.

One way to remove product build-up is to rinse your hair with a combination of shampoo and baking soda.

k18 Peptide vs. Olaplex: Pros and Cons Comparison

what is important to remember is both items are quality products that get the job done. However, it takes longer and multiple uses to see results when using Olaplex.

K18Peptide works in four minutes on all types of hair.

What are the benefits of using k18peptide?

  • Works on all types of hair in just four minutes.
  • k18 restores, strengthens, softens, and adds bounce to hair.
  • The product reduces breakage, split ends, and colour fade.
  • Cruelty-free, vegan, and colour-safe.
  • Reduce frizz
  • Reverse damage.

The Cons of Using k18Peptide

If you are prone to allergies, speak with your stylist before use. Alternatively, you may spray a small amount on your elbow to test allergic reactions. The idea is, apply the product on a clear patch of skin, then wait 24 hours. If you notice any negative reaction, it means that you are allergic.

The good news is very few people have reported experiencing allergic reactions to k18.

What are the Benefits of Using Olaplex?

  • Reverse and hair damage.
  • Reduce frizz.
  • Add shine and smoothness to hair.
  • Restore and strengthen hair.

The Cons of Using Olaplex

As mentioned, Olaplex takes longer to work. That is. You see results after three or four uses.

Furthermore, there are too many Olaplex products in the market (1 through 8), making it difficult for home users to figure out what item is for professionals only and what is more suited for home use.

Additionally, multiple users have reported burning and itching or a raised red rash after using Olaplex.

Summary: is k18 better than Olaplex?

The short answer is if you want to see results faster and are prone to product allergies, go for k18peptide. Because -it is a colour-safe-vegan product that will restore your hair faster, and naturally. On the other hand, Olaplex requires cumulative treatment. That makes it okay for home use. But unreliable in a salon setting. Also, the number of Olaplex products on the market 1,2,3,4,5,6,7,8 can make it difficult to know which product is suitable for which setting.

The long answer is, both products restore, strengthen, and soften hair when used as demonstrated above. So, for your first application, we recommend that you get the treatment done at the salon.

Overall, if you are looking for a substitute product that works just as great as Olaplex, k18 Peptide is the way to go.

However, the debate is still on, and some stylists are on the Olaplex team while others, I included, have fully embraced K18. What we want to know is what is your experience using either product? Tell us in the comment section.
