Osmo Straighten Up is a keratin smoothing complex that works with styling irons to transform your curly, unruly locks, while retaining the hair's natural moisture.

It locks in straightness for up to 3 days without weighing 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. Comes in a 250-ml bottle.
