smooths frizz [SEP] it has a relatively inoffensive odor but i prefer unscented products but the special ingredient that glues split ends back together a poly electrolyte complex made from polyquaternium and pvm ma copolymer does not seem to be available in any unscented products read the beauty brains blog forum for more info about this ingredient this is billed as a split end mender but the same mechanism seems to glue down the scales that produce frizzy hair my hair looks smoother darker and shinier when i use this it does not hold hair so i use it first then use a styling product
