My eyebrows were itching really badly. I began using different types of astringents on them such as alcohol, peroxide, vaseline, and  face creams. They don't itch nearly as badly as they did  but after a day or so I can see what looks like a crusty scab forming. I can't stand it and will pull the crust off with tweezers.  I'm wondering if age could have something to do with it as I just turned 69.
