curl serum

Most curl serums and oils are used as leave-ins: apply to damp or dry hair and distribute evenly. Common directions include dispensing a pump or a dime-sized amount and working it through mid-lengths to ends. Note: while most are leave-in treatments, at least one oil product in the results includes a rinse step in its directions.

Available sizes in the search results include 3.2–3.3 fl oz, 5.1 fl oz, 6 fl oz, 8 fl oz, 12 oz (12 ounces), 16 fl oz, and 20 oz.

These products target a range of hair: coarse, frizzy, thick, curly, and textured hair, with some formulas labeled specifically for curly hair and others marketed as suitable for all hair types.

They commonly advertise frizz control and smoothing, shine enhancement, moisturizing or conditioning, curl definition/curl enhancing, and damage repair or strengthening.
