Redken sells this as a 25-in-1 leave-in: detangling, shine, anti-static, moisture, less breakage and split ends, and heat protection among them. It is applied after shampooing or between washes, and Redken states it can be mixed with one of its styling products.

The gap is the one that matters in this family. There is no protection temperature on the listing. The ghd spray on this site states 230 °C (446 °F); this one gives no figure at all, so there is nothing to match against the maximum setting on your straightener.

That does not make it a bad leave-in. It makes it a leave-in with a heat-protection claim you cannot check, and the honest thing is to say which of the two you are buying it for.

What people ask about this

Why does this page keep coming back to the temperature?

Because it is the only comparable number in the category. A straightener publishes its maximum in degrees; a heat protection product either publishes one too, or it does not. The ghd spray in this same family states 230 °C (446 °F). This one states nothing, and that is a real difference between two products otherwise sold for the same job.

Is 25-in-1 meaningful?

It is a count of claimed benefits, not a specification. Redken lists detangling, shine, anti-static, moisture, reduced breakage and heat protection among them. None carries a published measurement, and this page does not repeat the count as though it were one.
