$0-10. I don't know how long it takes me to go through my Pantene shampoo and conditioner but that's all I buy for my hair, IDK how much they are, but they're not expensive.
I bought my Sedu and blow dryer 2 years ago and since then I haven't bought any other appliance. Next year I may get the new Sedu and one of those clipless curling irons, but I haven't decided yet.
