Now, I don't normally recommend hair styling products because my hair usually looks shite with them all. But I tried the L'Oreal 3 day straight heat protecting spray and it is fantastic. Just blew my hair dry and then went over it briefly with my straighteners and I got smooth and sleek hair which didn't frizz! Usually even if my hair looks okay when I do it, by the time I get to work, it goes horribly frizzy.
And it is on offer in Boots at the moment for only £3.99!
