Leg irritation

For the past few years I’ve gotten severe irritation on my legs after showers. I can’t remember exactly when it started and what triggers it exactly. I had an allergy test before this began and I discovered I have a mild allergy to grass. I’ve read up on it and it sounds like it’s from my soaps or lotions. Initially I started using hypoallergenic soaps and fragrance free lotions. Now I also use fragrance free soaps and 1% hydrocortisone to help with flare ups. Sometimes it happens, sometimes it doesn’t. When it does it feels like I want to rip my skin off because my legs get so irritated and itchy. It’s weird because it’s isolated to my legs only. I hate having to remove fragrances because it feels like I’m not even bathing anymore. I’m a non practicing esthetician so I should be more knowledgeable about these things but I’m not. Has this happen to anyone? What do you do to resolve it?
