EvoEvo Lockdown Smoothing Treatment

BUY at Birchbox

If frizzy, unruly strands are the bane of your existence, gliding this leave-in treatment through just-washed hair for a smooth, shiny look will relieve any hardship. The formula does damage control in the form of ingredients like polyquaternium to reduce frizz, detangle, condition, and prep locks for styling. Once they dry, you'll be able to manage them better and straighten, curl, and style to your heart's content.
