The Garnier Sleek & Shine line includes serums, sprays/mists, oils, liquids, and creams for smoothing and styling hair.
They target dry, frizzy, and dull hair and are described as suitable for straight, wavy, and curly textures; some listings also call out coarse, normal, or 'all hair types.'
Apply a small amount (or one pump) of the anti-frizz serum to wet, damp, or dry hair and leave it in—do not rinse. The oil can be used in-shower or applied as a leave-in after blow-drying to tame frizz.
The products describe up to 72 hours (3 days) of frizz control—even in 97% humidity—when used with the system, and several listings note humidity-resistant formulas.
Net weights shown across listings include 3 fl oz, 3.75 fl oz, 5.1 fl oz, 6 fl oz, 12.5 fl oz, 24.5 fl oz, and 33.8 fl oz.
The straightening mist is described as protecting hair from flat-iron heat (heat protection up to 450F) and producing up to a 48-hour straight finish when used before flat ironing.
Used together as the shampoo + conditioner + anti‑frizz serum system, they state up to 72 hours (3 days) of frizz control—even in 97% humidity. The flat‑iron straightening mist describes up to a 48‑hour straight finish.
Reviewers commonly report strong smoothing and frizz control, increased shine, and softer hair. Many note the formulas are non‑sticky/non‑greasy, easy to apply on wet or dry hair, and often considered good value.
