One pump of Paul Mitchell’s Super Skinny Serum is all you need smooth, condition and seal strands. Lightweight silicones do the heavy lifting and thermal protecting ingredients safeguard from damaging heat stylers, so hair is left soft, shiny and healthy. Best of all, the unique formula displaces water in wet hair, reducing drying time by a whopping 30 percent—which explains its “bestselling” status.
