I don't know if it will do that, Hatty.
I have short(ish) white hair, with a bit of a wave. I normally blow dry it with a bit of mousse.
If I don't do this it just sits very flat & lank looking.
With the redken stuff it looks exactly as if I had blow dried it & stays in place & looked good after a 20 minute, going right under, sea swim. And it doesn't feel as if I have any product in my hair.
I am liking it because I like to travel light & it means I won't have to take a hairdryer.
There are 3 strengths & I use the middle one (just right).
I've just googled it & it is now discounted in lots of places, down to £10 - £11 which is a lot cheaper than the £17 I paid for it!
I don't wear much make up & am not one for lots of products but for my hair this stuff is amazing.
