keratin serum

Many keratin serums are formulated for all hair types, and several specifically note suitability for frizzy or coarse hair. In practice, they commonly suit both general use and frizz-prone textures.

Keratin treatments appear in several formats, including serums, sprays, liquids, cream-style smoothing stylers, and wand applicators designed for targeted edge or flyaway control.

Common ingredients include keratin or plant-based proteins; nourishing oils such as argan, jojoba, and avocado; reconstructive actives like creatine; and botanicals or actives such as kombucha, red algae, and phytic acid. Some formulas also list minerals or other specialized extracts.
