Product Description

Transform unruly, wavy or frizz-prone hair into sleek, blemish-free locks with Osmo Straighten Up 250 ml – a vegan keratin-infused smoothing fluid designed to lock in straightness for up to three days or until your next shampoo. This lightweight formula seals in moisture while protecting against thermal damage, preserving natural oils and leaving hair soft, shiny, and easier to manage.

Perfect for all hair types, it works hand-in-hand with heat styling tools—from blow dryers to flat irons—to extend straight styles without added weight or buildup.
