I have a friend (shout out to photographer Yael Silberberg) who, upon moving, packed a whole suitcase full of Sabon. That's the level of cult following we're talking with this beauty brand that has been around for a quarter of a century. They're best known for their scrubs and their ready-to-gift packaging — meaning that these are products that look and feel a lot pricier than they are.
Ahava makes Dead Sea-mineral skin and body products. The Dead Sea is so purifying that people from all over the world come to soak (or float) in it. Many take mud from the area back home with them. It's a messy endeavor and there's really no need given Ahava's extensive range of effective products.
Moroccanoil is best known for their signature hair oil, which has inspired countless (less effective...) knockoffs. But they also have a range of other products in their signature musky-vanilla scent (it's aaaamazing).
Dr. Fischer has over 1000 SKUs! They're known worldwide for making products targeting a wide variety of concerns as well as ones suitable for sensitive skin, including babies.
