Osmo Straighten Up is a straightening complex that works with styling irons to transform your curly, unruly locks.
It does this whilst retaining the hair’s natural moisture, too.
It locks in straightness, without weighing the hair down, and protects against heat damage. It also controls frizz and promotes shine.
Simply spray evenly over damp or wet hair, section by section, avoiding the root area and then comb through.
Then blow dry hair with a large barrel brush before using straightening irons in sections.
Available in 250ml.
