Tame your wavy, coarse or frizzy hair with the Joico Smooth Cure Leave-In Rescue Treatment, a concentrated, heat activated anti-frizz treatment. Created to mimic the results of an in-salon straightening treatment, this supercharged formula intensely smoothes & softens hair whilst reducing damage from thermal styling. Combing & brushing become a pleasure once more, & your hair looks sleeker than ever. The secret of the Smooth Cure Leave-In Rescue Treatment is hydrolised keratin, which penetrates the hair's cortex & replenishes lost protein. Joico's exclusive formaldehyde-free Kera Shield Complex of keratin, brazil nut oil, & tucuma butter strengthens & provides frizz-free care for up to three days. After shampooing & conditioning hair, apply a few drops of the treatment to your hands & work through damp locks. Blow dry as usual, & enjoy a super smooth blowout.
