I realise this will only appeal to a niche audience but 300ml Schwarzkopf Got2b GIued Blasting Freeze Spray for only £2.69 at Savers. This is their regular price too which is astounding. This is the only hair spray I trust against the fight with British weather. These usually sell for over £4 each elsewhere. Boots have a deal at the moment for £2.86 if you haven't got a savers near you but bearing in mind that is a limited offer price.
