How to treat your hair after bleaching/coloring A bonding treatment is so essential after a chemical treatment because it protects the bonds in your hair from breaking and helps to rebuild bonds that broke due to chemical damage! You could either use Olaplex No.0 & No.3 or Curlsmith Bond Curl Rehab Salve. The difference is that Curlsmith Bonding treatment contains protein, it's a bigger size, and not as pricey as Olaplex No.3.@Curlsmith Official #fyp #colortreatedhair #curlyhair #curls
