What’s the difference between Olaplex and K18?

K18 vs Olaplex. Olaplex vs K18. Both of these little legends have taken the hair world by storm. One cannot simply dye their hair without hearing of them! But what is the real difference between two of the most popular treatments on the market? Well, you’re about to find out!
 
Let’s get a bit technical here. The hair is made up of polypeptide chains. These chains are held together with disulfide bonds. Heat (from blow drying, curling or straightening) and chemicals (from bleaching and colouring) break down the disulfide bonds and polypeptide chains, resulting in damaged, brittle hair.
 
So how does Olaplex work? This OG hair repair treatment has been a game-changer for years. It rebuilds broken disulfide bonds in the hair to restore hair strength. Basically, it’s like super glue for your hair!

Now, onto K18. How does K18 repair my hair? This little guy reconnects polypeptide chains and also reconnects disulfide bonds using a patented bioactive peptide that penetrates deep into the hair shaft to repair broken bonds. It’s like a tiny construction crew working to rebuild the foundation of your hair nawww.

So, is K18 better than Olaplex? Well, it really depends on what how damaged your hair is, your budget and your application preference. K18 is great if you’re dealing with severely damaged hair and need some serious repair work done. Olaplex, on the other hand, is a great all-around treatment that can be used for maintenance as well as repair.
 

How do I use Olaplex? No.3 is a pre-shampoo hair treatment. So before shampooing, dampen the hair and apply No.3 from roots to ends. Wait at least 10 minutes, rinse well, then shampoo and condition. Use once a week or up to 3x per week for very damaged hair. STYLIST TIP: Olaplex No.3 can work its magic all on its own, but when you dampen with No.0 (instead of water), you’re taking things to a whole new level. We’re talking 68% more repair…
 

How do I use K18? When it comes to K18, simply wash your hair, skip conditioner, towel dry and apply K18 as your leave-in conditioner. 4 minutes later and you’re done! Use for the first 4-6 consecutive washes and then every 3 or so washes after that.
 

K18 and Olaplex are both amazing hair treatments that can help repair and prevent damage. Which one you choose really depends on your hair needs and personal preferences. Whatever you pick, your hair will thank you for it. Happy hair days ahead!
