answer:Yes and no. Many shampoos are similar, yet some good ones are distinctive enough to treat your hair better. My hair is peculiar enough that it does not look healthy unless I use one of a few shampoos. Same with pot pies. Marie Calendar pot pies are too doughy, the cheap ones often don’t have crust on the bottom. The M. Calendar ones at least have good size chunks of meat. By far the best (IMHO) are Swanson’s, but not he Hungry Man, the regular ones for good crust to filling ratio. I am particular about what chemicals I’ll expose myself and the family to, so I am picky about detergents and soap, and often pay a little more for a healthier brand. And I found buying quality clothes is important, because the clothes last a lot longer. So no, not everything is the same.
