How to Use Olaplex Hair Products: The Beginner's Guide (2024)

Whether you’re guilty of over bleaching your hair or using too much heat styling, we’ve all put our precious strands through the ringer. However, one brand that pops up again and again as the ultimate hair savior is, of course, Olaplex. In fact, it took the number one spot as the hottest hair care brand in our 2021 Hair Report.

We’ve all heard the rave Olaplex reviews and seen the impressive before and afters, but what with a slightly confusing numbering system it can be difficult to know where to start. That’s where the hair aficionados at Cosmetify come in. We’ve done the hard work and have created a foolproof how-to guide for all our favorite Olaplex products.

What is Olaplex?

Firstly, we’ve got to explain what makes Olaplex so special and why we need their bond maintenance treatments in our lives.

Olaplex has previously been a salon only treatment, which professional stylists use to help repair and rebuild damaged hair. Luckily for us, you can now get your hands on their scienced-backed hair treatments in the comfort of your own home.

Their products help repair all types of chemical damage, like relaxing and keratin treatments, as well as perms and coloring. If you’ve managed to avoid the bleach but still have damage from heat styling, brushing or even environmental stressors, the Olaplex products are still suitable for you.

No matter if you have curly, fine, thick or coarse hair, Olaplex works for ALL hair types.

What does Olaplex do?

But what does Olaplex actually do? Here’s the snazzy science bit.

Olaplex isn’t like other hair treatments. While other hair care brands simply smooth over the problem, the Olaplex formula actually repairs the damage using their patented single ingredientBis-Aminopropyl Diglycol Dimaleate.This workson a molecular level to restore your hair. In fact, it is the only patented bond builder in the biz.

Basically, over styling and hair stressors can break the strong disulfide bonds in the hair. These bonds are necessary for a healthy-looking ‘do. This breakdown then creates a single sulfur hydrogen bond which can pair with three oxygen molecules. If this happens it produces cysteic acid which can eat away at the protein in your hair. This is bad news for our beautiful tresses!

So, what Olaplex does is pairs quickly with the single sulfur hydrogen bond to link the bonds back together to recreate the healthy disulfide bonds.

Still not sure what that means? Don’t worry, just know that salons across the globe use Olaplex treatments to achieve soft, shiny, strong and healthy-looking results.
