So the last couple of times that I dyed my hair in a salon, I felt like I was having an allergic reaction. Head felt tight, and I felt panicky. I remember my mum having a reaction to hair dye years ago so am anxious about developing an allergy to it. So I haven't dyed my hair since mid December and I have that awful white line at the roots. My hair was naturally dark brown. I don't mind going grey but I'm hating this in between bit and feel really self conscious :(
