I have also had a severe allergic reaction to PPD. It happened Dec '06. I ended up in Urgent Care getting a shot, meds and an EPI pen to carry! ;( Since that time, I went to an allergist who confirmed I am allergic to to PPD and I was doing "full weaves" on my hair with the foils. I was doing it that way to avoid contact to my scalp. Well, here it is a year later and guess what, I'm still allergic and having problems. Long story short, the doc says even just inhaling the fumes may cause me to react. What hair salon doesn't have fumes???
Anyway, I'm researching what others are doing. I see that there is a lot more info on the net just this past year with people becoming allergic to PPD. (All of it is bad news.) I think I am going to try and set up a forum/support group for people like us. (On network54 forums)
In the meantime, I'm seriously considering giving up at the salon and just using Clairol Loving Care and see how it goes. I DO NOT want to be gray either (just yet anyway, I'm not that old).
Take care,
gogo
