Some people can call Olaplex exciting, but it has retained its place as the best hair-strengthening treatment for nearly half the decade. It has become a hair stylist’s favorite, and most stylists use Olaplex products.

Ingredients | K18 Hair VS Olaplex 

K18 Hair 

K18 Peptide technology is a unique peptide technology. The primary way to fix this hair issue is by considering your hair as polypeptide chains, connecting and running vertically. These bonds can be broken, and we need to use builders. These builders cannot be patched or glued together. We use some bond builders that can change the hair’s outer structure, making it look glossy, but we need to work on the molecular or cuticle level.

K18 peptides are responsible for replicating the entire design and healing them as if they weren’t damaged. Dicaprylyl ether is an emollient in the hair mask. It is light and silky in texture. It makes your hair very soft and smooth without leaving a greasy feel on your hair. 

Hydrolyzed wheat protein can strengthen the hair shaft. It provides an enormous amount of moisture to your hair. The protein avoids breakage in hair, and it can add shine too. Overall it can improve the appearance of your hair. Citric acid is essential in the serum to reduce your hair’s frizz.

It can improve the manageability of your hair and enhance the appearance of your hair. Geraniol can promote hair growth in your skin. It nourishes your scalp and balances the production of oil in your scalp. It can reduce the secretion of sebum too. Maleic acid is present in it too. It is an organic acid that plays a role in strengthening hair and preventing further damage to your hair. 


Olaplex has many products for strengthening your hair bonds. However, we are only looking at repairing and healing hair. They have a pack of products named “The Complete Hair Repair System,” which contains three products for the same. One is an Intensive Bond Building Treatment, Hair Perfector, Hair Maintenance Shampoo/Conditioner, Bond Smoother Bond Multiplier, Styling Oil, and Bond Intense Moisture Mask. Olaplex has a patented active ingredient to heal damaged hair. The active ingredient is Bis-Aminopropyl Diglycol Dimaleate.

You cannot get this treatment done at home, and you’ll need to visit the salon at least two times for noticeable results. This is a step-by-step process. First, we use the Bond Multiplier to rebuild, disulfide broken bonds, and begin preventing hair damage. It is compatible with all color lines, clay, and powder. Bonding Perfector is applied then to continue to rebuild and restore healthy hair. 

The next would be the 4-in-1 Moisture Mask. This contains ceramides and amino acids for providing intense moisture to your hair. It suits all hair textures and types. It is perfect for dryness and other damaged hair especially. This can be considered a deep conditioning treatment. The bond-building treatment kit rebuilds hair bonds and protects hair integrity too. Hair perfector can be used at home, and it reduces breakage in your hair and improves the feel and texture of your hair. The bond maintenance bond and conditioner are for you to use at home. They make your hair easy to manage and frizz-free.

It can give you shine and remove all the hard water and chemicals from your hair. There is increased softness and shine after using these products. Next comes the bond smoother, a styling cream that hydrates, protects, and eliminates frizz. This is great for chemically treated hair and reduces the styling time for your hair too. The bonding oil is one of its kind as it can increase shine and softness in your hair. Similarly, the moisture mask is responsible for adding shine and moisture to your hair for repair.

The formula has been extremely beneficial as my salon treatments are always Olaplex. The products are well made and have amazing benefits. It has reduced the dryness in my hair and returned the bounce to it. There is a unique softness in my hair. I have been doing these sessions every two weeks, and there has always been a good improvement.

However, there were some complications some time back. First, it started becoming very expensive, and secondly, I have been having hair fall after using it recently. My scalp started to itch, and I had a tremendous amount of hair fall after using it recently. I am questioning if I should use these products any longer. There are newer and better-performing products from brands like K18 Hair, which can show faster and more effective results. Being loyal to Olaplex, I might try it a couple more times for a better experience.”
