Joico's 7-second Defy Damage In a Flash is a unique liquid-cream treatment that instantly helps strengthen hair structure and create bonds. The product undergoes an exothermic reaction on contact with water, giving it the consistency of a liquid cream that helps boost hair strength 20-fold. Defy Damage In a Flash 7-second bonding agent is formulated to protect hair strands from the daily effects of heat styling, UV exposure and environmental pollution, which result in dry, dull, lackluster strands. This treatment is lightweight, so it never weighs hair down, and it's ideal for all hair types and textures that need to be intensely strengthened and nourished.

After Defy Damage shampoo, apply Defy Damage In A Flash treatment directly to wet hair (from mid-shaft to ends). Massage into hair until the product forms a cream. Leave in for 7 seconds and rinse.
