Bond Repair Treatments: We Know What the Brands Say, What Does the Science Say? by Charlie Westphal

If you have ever bleached, colored, relaxed, flat-ironed, or even just brushed your hair too aggressively, you have probably seen the phrase “bond repair” somewhere in your feed. In the past five years, bond repair has moved from a niche salon treatment to a category now with shelves of products promising to “rebuild,” “restore,” or “relink” the bonds inside your strands. Some of the most familiar treatments are from brands such as K18, Olaplex, Epres, Living Proof, Curlsmith, Innersense, and As I Am.
