Why Soap Might Be the Problem: Eli Halliwell on Rethinking Clean
Imagine if "squeaky clean" was actually a sign your skin is in distress, not a sign of health. In this episode of Imagine If, host Janet Kraus sits down with Eli Halliwell, co-founder of Hairstory and founder of Sans Savon, to question one of the most basic assumptions in personal care: that soap is good for us.
Eli explains how the same detergents used to clean dishes and laundry ended up in shampoo and body wash, stripping away the skin's natural oils and microbiome and triggering a cycle of dryness, irritation, and overuse of moisturizers and styling products to compensate. He breaks down the simple chemistry of amphiphilic molecules (the "oil-loving, water-loving" compounds behind every cleanser) and explains why foam is usually a red flag for over-stripping, not effective cleaning.
It's a fascinating look at how questioning a 100-year-old assumption about hygiene can lead to a more sustainable, less wasteful approach to everyday self-care.
