Does anyone know if Pantene Pro-V hair shampoo has changed its formula? The last several times I've washed my hair with the new bottle, it's left my hair feeling yucky. It takes forever to wash out the shampoo now, and my hair feels all slick and oily while washing; I can't get my hair squeaky clean the way I used to be able to. I checked the bottle, and it's the same shampoo--not for dry hair and not with conditioner. It's really annoying. I'm considering switching to a different brand.
