fructis sleek and shine serum

The serums are labeled for dry, frizzy, dull, and coarse/frizzy hair, while one formula is listed as suitable for all hair types. Reviewers also report using them on curly, fine, color-treated, and grey hair.

The formulas emphasize sustainably sourced Argan Oil (Moroccan oil). The anti‑frizz serum lists a Kera‑System in its formula, and the heat‑activated Sleek & Stay formula highlights an alpha‑silane ingredient.

Dispense about one pump into your hands and apply evenly to damp or dry hair—do not rinse. For the anti‑frizz serum you can style with a brush and blow dryer; for the heat‑activated Sleek & Stay, blow‑dry first then flat‑iron to thermo‑lock the sleek finish.

Product descriptions list the serums as sulfate‑free and paraben‑free. One formula is described as blended without parabens, phthalates, and DMDM Hydantoin; other claims noted include aluminum‑free and dye‑free.

Reviewers commonly describe the serums as non‑sticky and non‑greasy, easy to apply to wet or dry hair, and note that a little product goes a long way.

Shoppers report reduced frizz, improved smoothness and shine, and softer hair that generally doesn’t feel weighed down; some users also note longer‑lasting styled looks through the day.
