I've used hair dye in the past with no side effects, however, the last time I tried one (1 month ago) my scalp started tingling so I rinsed it off immediately.
Does this reaction mean that I am now permanently sensitised to hair dyes, or is it worth giving it another go? Should I wait a few months? I had a baby a few months ago and am bfing - do the hormones have an impact?
Help! I'm going greyyyy!
