Why would you feel silly? Coloring your hair has been popular by both sexes since has been in existance, and the ancient Egyptians mummy's still have the henna on their hair. I have been there to witness it myself!

As far as the allergy, 30% of the general population has an allergy to something, so count that as 1 in three. The fact that your allergy is to PPD, does not make it more, or less significant. So, don't beat yourself up over it! READ, and study, knowlege is power. You can do a lot to make sure you don't get that bad again. There are many people that do not know what they are allergic to as soon as you do, so, you are lucky in a way. I hope you are feeling better, and that you are on your way to healing. If you have any scabs, don't pick at them!! Good luck!!
