can anyone explain this to me?
Does anyone know anything about the body chemistry of hair? I gave one of my co-workers shampoo for Xmas, because her wet freshly washed hair kept giving me a migraine. So I gave her the shampoo that I myself use. Well, a few days ago - while looking over my shoulder at my computer, she took her hair down from a bun it had been in since it was wet - and the scent gave me an instant migraine. Yet she had shampooed her hair with the EXACT same shampoo that I use on my own hair. Am I going crazy? How does this make any sense?
