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.

Key Benefits

  • Long‑Lasting Straightness: Keeps hair straight and sleek for up to 3 days or until your next wash.

  • Keratin + Soy Protein Formula: Smooths and reduces frizz while strengthening strands.

  • Thermal Protection: Shields hair from heat damage during styling.

  • Retains Natural Moisture: Maintains the hair’s natural oils for softness and shine.

  • Vegan & Cruelty-Free: Ethically formulated and ideal for conscious consumers.

  2. Blow-dry using a large-barrel brush to smooth hair.

  3. Section dry hair and seal with flat irons to lock in straightness.

  4. Enjoy smooth, straight hair that lasts until your next shampoo—typically up to 3 days.
