Frizz is a humidity problem and Lockdown is the engineering solution. This intense leave-in treatment is evo's answer for unruly, frizzy, or resistant hair that refuses to behave - a lightweight formula that smooths and softens on contact, locks out humidity, reduces static and fly-aways, and improves manageability without weighing the hair down. It works on its own or as a prep step before heat styling, and it's particularly strong for colour-treated hair that needs extra conditioning support alongside the smoothing. Who's It For Frizzy, unruly, colour-treated, or humidity-sensitive hair Anyone who blow-dries frequently and wants a leave-in that does actual smoothing work rather than just adding moisture Works on all hair types Key Benefits Smooths and softens hair with an anti-static formula Locks out humidity to prevent frizz from returning throughout the day Reduces fly-aways and static Locks in moisture to enhance condition and improve detangling Works on air-dried or heat-styled finishes Suitable for colour-treated hair Lightweight - won't weigh hair down or affect volume Scent Profile Fruity, melon, floral, green, and sweet. A light, fresh fragrance that dissipates during styling. Key Ingredients Polyquaternium-37, -72, and -11 - A trio of conditioning polymers that coat the hair shaft, reduce friction, smooth the cuticle layer, and create the anti-static effect that keeps fly-aways under control. Amodimethicone - A targeted silicone that selectively deposits on damaged or porous areas of the hair, smoothing rough cuticle zones and adding a light conditioning layer where the hair needs it most. Phenyl Trimethicone - Adds a light, non-greasy shine and helps repel humidity by creating a barrier on the hair surface. Cetrimonium Chloride - A conditioning agent that helps detangle and soften, making the hair significantly easier to manage post-wash. How To Use Apply evenly to damp hair after washing. Do not rinse. Air-dry for a smooth, natural finish, or blow-dry with heat tools for an even smoother, more polished result. Can be used daily. Why MASC Recommends This Lockdown is the leave-in we recommend to anyone dealing with humidity-driven frizz or hair that goes everywhere the moment it gets near moisture. The anti-static triple-polyquaternium formula is doing real work, not just conditioning - it actively prevents the frizz from reforming throughout the day. For anyone who blow-dries regularly, it also works as an excellent prep step that accelerates drying time and improves the finish.
