If you have hair extensions how long should you wait to wash your hair?

I have almost a full head of hair extensions. I just got it down alittle over a week ago and my hair is starting to get stiff.If you have hair extensions how long should you wait to wash your hair?
are they sewn in or glued? If sewn in you can wash them now...be careful if they are glued in and don't use shampoo with any oil in it, it will slip right out. Hope this helps.If you have hair extensions how long should you wait to wash your hair?
since shampoo is oily use a bar soap to wash your hair dont put to much conditioner and not to much product :)
