Best Hair Serums and Oils from Top Stores

Updated October 11, 2026

Compare the best hair serums and oils from top stores in one place, for shine and nourishment.

Hair serums and oils on this page are priced from $29.9 up to $280. Most products are labeled as serum, oil, mist or treatment, indicating lightweight or nourishing formulas from Moroccanoil, Olaplex, Oribe and R+Co.

Serums often contain silicone or dimethicone for shine and frizz control, while oils like argan or prickly pear add deep moisture. Look for ingredients such as vitamin E, botanical extracts or lightweight carrier oils that won’t weigh hair down.

When selecting, match the serum or oil to your hair’s needs: a smoothing serum for frizz, a strengthening oil for breakage-prone strands, or a brightening mist for color-treated hair. Apply a small amount to damp hair for best absorption.
