What are the top-rated hair serums on Sephora? 

Hair serum can whip your hair into shape with a dose of highly potent ingredients. Whether you want to control frizz, boost shine, reduce tangles, enhance texture or protect against damage, you’re sure to find a hair serum to meet your goals. Hair serums are usually silicone-based and used as a styling product on damp hair. They coat the surface of your hair, which means nearly every formula is effective at fighting frizz. But some hair serums feature specialized formulations that specifically target different hair types. These differences help you find an option for straight, curly, coarse, fine, color-treated or damaged hair. Many serums also work as heat protectants, so you can apply them before using a flat iron, curling iron or blow dryer

If you’re on the hunt for a high-quality hair serum, here are the most popular options at Sephora to give you luscious locks every day.
