I had a severe allergic reaction to over the counter hair color that I have used for 3 years, about 2 weeks ago. I had to see a doctor. My face swelled up, my eyes were almost swelled shut, I had blisters pop up on my scalp. The P. A. gave me three shots, and two prescriptions. She told me I needed to embrace my grays, she recommended, not coloring my hair again. I'am 48 years old, so I'm not quite ready to do that. Do you have any suggestions?
