Editor Quote: "The buildable formula is easy to use without worrying about overdoing it, so I usually apply a little every day in between washes. I'm still surprised by how soft my curls feel after applying it. Its star ingredient, Bis-Aminopropyl Diglycol Dimaleate, is part of Olaplex's patented Bond Building Technology™ that repairs damage by relinking broken bonds. I'm used to running my fingers through my dry split ends, but the bonding oil really helps to smooth and hydrate my usually coarse, dry hair." — Angela Elias, contributing shopping editor
