What exactly are you allergic to?

Because you can get home-made soaps from the markets that don't have half as many of the nasties that commercially made soaps do.
I have no idea exactly what it is i'm allergic to but I am incredibly itchy for about an hour after having a shower. I have started taking an antihistamine before I shower which reduces the itch.

Actually, we have a soap shop in town so I might go in there and see what she's got. I didn't even think of that.
