Repairing splitting, damaged hair can be a headache on its own. Scanning the aisles for the proper magic solution or concocting at-home mixtures to address the compromised follicles - it can be so overwhelming, time-consuming, and costly. So, let’s narrow down the options to two salon grade treatments: Olaplex and K18 hair repair. In this blog, we’ll explore the differences in the two and demystify the purpose of each treatment.
Damaged hair isn’t something to be ashamed of! It is the very result of various factors, including everyday stress, color application, chemical treatments, and styling – all these components can contribute to structural damage of your hair’s integrity. Even so, these two science-backed hair solutions have provided an effective remedy to counter the damage done to the follicles.
Olaplex is a patented Bond Building Technology - its key activator is Bis-Aminopropyl Diglycol Dimaleate. It addresses the damaged hair by repairing broken disulfide bonds to rebuild internal hair structure after chemical or weather damage. The wonderful thing about Olaplex is that it works as a system: it can be used in a salon setting or at home - for example: No.1 & 2— are used professionally and No.3, 4, 5 may be used at home, providing salon-grade hair repair.
What exactly are the benefits? The Olaplex Bond Builder directly strengthens the hair, improves manageability, reduces breakage, and extends color longevity. The repair treatment is effective for all hair types – it is especially suited for those who frequently bleach,dye, or utilize hot styling tools. Another benefit: results are visible quite quickly but may require regular maintenance as effects can be diluted over time (as with most products and applications).
K18 Molecular Reset is a relatively newer bioactive peptide hair treatment that utilizes a patented peptide to reconnect broken keratin chains at a greater depth. It works as a leave-in molecular repair mask that works in just 4 minutes.
This K18 treatment penetrates the hair’s innermost layer, repairing and reconnecting polypeptide chains and disulfide bonds. This then provides a “full reset,” guaranteeing permanent repair by restoring the hair’s original elasticity and strength – not just short-term fixes.
This treatment is best suited for those with several damaged hair caused by bleach, chemical treatments and heat styling. The application is simple as well: you apply it as a leave-in-mask; rinsing is not required. It’s a perfect option for someone looking for instant softening, strengthening, and restoring bounce and smoothness.
Olaplex is the right choice for you if you have mild-to-moderate damage. If you frequently apply color, want stronger hair, and don’t mind the multi-step routine, this hair treatment might be the right choice for you.
However, for severely damaged hair, or very dry, brittle hair requiring fast or profound repair, the keratin chain repair may be right for you. This is because the K18 will provide you visible transformation in minutes. It also offers a simpler routine for those looking to avoid a multi-step process.
Some clients see a benefit in using both; Olaplex on a regular basis and K18 after major color or chemical events.
