Does anyone else find hair dye gives them a flare? I usually dye my own hair using home dyes, the past (at least) three times I'm sure its put me in a flare for a month or so until the dye has nearly gone. The first time I used a normal box dye (which I'd previously been using for years), 2nd time I tried a 'natural' one from a health food shop, and the last time I used henna! I can't understand how henna would cause a flare as it's all natural Any insight ladies?!
