By now we are all well-committed to protecting the skin from UV rays, but the commitment falls when it comes to hair. Those same damaging UV molecules sap both salon colour and moisture from strands, leaving you with a dry, brittle, dull ‘do. JOICO Defy Damage Protective Shield offers instant protection from damaging heat, UV, and environmental exposure. Simply apply prior to styling, to help build a defence against daily aggressors and leave hair feeling soft, shiny and fortified.
