My daughter has eczema and my sone is allegic to....Something....He's been to 2 different allergists and still can't figure out what's breaking him out. I digress, when they are itchy, the tub is still part of the remedy process. Neff has special soap and uses luke warm water when she has an episode because hot water makes it worse, and buddy takes an oatmeal bath before we administer any further medications.
All that said, I.....Mostly....Agree.....If your eyes or arms or something itch, it could be an irritant that you've encountered.....If it's your ass crack, anywhere on your crotch, under your arms, neck or behind your ears I'll recommend scrubbing that shit. It might not cure your itching but I feel better about being around your scratching ass.
