Here's Aussie babe Iggy Azalea basking in Miami's glam glow (she's there mixing biz with pleasure according to her instagram) looking slicker than your average in a, well, slicked-back hair-do. We must have! So we asked an expert: Helen Bradley, ASOS senior hair and make-up supervisor, who imparted the following know-how for your getting-ready pleasure. 

1. Blow-dry your wet hair straight (using a heat protector) and comb it back from your forehead using a paddle brush
2. Use a humidity-defying cream and comb through your hair from root to tip, and then run straighteners over the ends
3. Use a smoothing cream to give your hair that slick look
4. Use hairspray to keep it all in place
