There are lots of products. One I like, and use most summers if I'm having a real 'beach' type holiday, is made by the excellent French company Phyto and is Phytoplage Sun Veil. The Phyto products are available in shops like Space NK, and also on their website, and the HQ Hair website. I notice that Frederic Fekkai (available in same sort of places as Phyto) are also doing something similar. For cheaper products, I would go to a large branch of Boots and have a browse. I'm sure I've seen some.
