Best products for a textured bob?

[stripytees]

I've just had my hair chopped to a bob (again). Love having it shorter but my hair is naturally very straight and this rainy weather is making it look so flat. I use my straighteners to add some waves but what's a good product to make the waves stay and/or generally add some volume and texture?

Spray wax

Hi. My summer chop sounds similar! I use schwarkopf glu2b( yellow can) hairspray,and the root lifting powder to lift it and add texture and volume. If I can be bothered, velcro rollers/ blowdry round small rounded brush and straighteners are used to!! But it's usually all gone to pot as I leave the house/ it gets some rain on it! But hey the efforts there! Less product is more on my fine hair too
