The Joico Defy Damage Protective Masque has been specially designed to deeply nourish the hair while protecting against the effects of daily heat styling, UV exposure & environmental pollution that can lead to dull, lacklustre locks. The deeply replenishing hair mask is a powerful at-home hair treatment that works to rebuild broken hair bonds & reduce breakage. Penetrating deep within strands without weighing hair down, the hair masque infuses hair with a brilliant, bond-strengthening defence system to encourage heightened resilience & colour longevity. Hair is better protected against heat tools & feels instantly & touchably soft with glossy shine.
