amika Flash Instant Shine Mask is a 60-second rinse-out mask that takes dull hair to glossy, sealing the cuticle while softening and hydrating for a silky, smooth finish. Used together with amika Mirrorball shampoo, it was clinically shown to give 62% more shine.

Hydrolyzed flaxseed moisturizes and softens hair for healthy-looking shine, a blend of amino acids smooths the cuticle and boosts elasticity, and antioxidants hydrate and condition to fight frizz. UV filters help keep colour vibrant between salon visits.

How you use it depends on your hair. Fine or oily hair can use Flash after shampoo in place of conditioner; thick or dry hair gets it after shampoo and conditioner. The 200 ml (6.7 fl oz) bottle has a twist nozzle for applying it section by section.
