I am such a tea addict. My current favourite is Taylor's of Harrogate Yorkshire Gold, although I wouldn't say no to Assam, Bewley's Original, or practically any black tea from Whittard.

If you want something with a caramel flavour (such as Pepsi/other kinds of cola), then I would suggest a Rooibos and Vanilla. I think Tetley makes one, although the one I have sitting in front of me is from Marks and Spencer.
Products I like:
Shampoo: Giovanni 50/50 and Dr Organic Manuka Honey (mixed together)
Conditioner: A mixture of Superdrug Raspberry and Macadamia Nut and Tresemmé Naturals Nourishing Moisture

Leave-in: Giovanni Direct
Gel: LA Looks mega mega hold #9 [yellow] hair gel

Nota Bene: If I don't have access to my beloved LA looks, then I use a mixture of VO5 Mega Hold Styling Gel, Boots essentials extra firm hold [purple] hair gel, and Garnier Fructis Camouflage Gel.
