Bren,
I have been wearing wigs for years. The styles have come a long way from the stiff overdone styles of the past. Synthetics are the least expensive and European hair customs are the most expensive. Whatever you get - mess it up a bit so it will look more natural. I turn mine upside down and give it a good shake. Use a travel size spray bottle with water and give it a shpritz and use a pick, comb or your fingers for a quick styling. Tell the person who styles it that you want one that is easy to change around. Don't fall for sales pitch for special products. Any good shampoo and conditioner will work. It is very important to rinse all shampoo out and use a conditioner.
Have fun with your new "toy" whatever color you choose.
Enjoy that trip to Cyprus
