Osmo Straighten Up 250ml

Description

Osmo Straighten Up is a unique keratin‑based straightening complex that works in tandem with styling irons to lock in long‑lasting straightness while safeguarding hair from thermal damage. By retaining the hair’s natural oils and moisture, it delivers smooth, sleek results that last up to 3 days or until the next shampoo. Apply by spraying evenly over damp hair section by section, comb through, blow dry with a large barrel brush, then use a straightening iron to set the finish. Suitable for all hair types and completely cruelty‑free.
