1. Hot Water Strips Natural Oils (Dry Skin After Shower)
One of the biggest culprits behind post-bath itching is hot water. While a steamy shower feels relaxing, it strips away your skin’s natural oils (sebum), leading to xerosis cutis (extremely dry skin). Studies show that water temperatures above 104°F (40°C) significantly worsen skin dryness .
