I used to dye my hair fun colours decades ago when I was young and it was all fields and then I gave up on all that and let my hair grow back to its actual colour and haven't dyed it for years.
Recently I bought a box of brown dye to deal with my many greys and the instructions were basically.
Do a patch test.
No. Seriously, you must do one.
If your skin starts to blister don't' dye hair.
If your head explodes dial 999 immediately.
So I'm googling as I never did a patch test in my life so surely I'm fine and then I find out that dye allergy has a cumulative effect and can strike at any time. We've got a nasty history of skin allergies in my family and google has scared the shit out of me. Why do I google? I know not to google. But anyway henna can also cause bad reactions now? and meanwhile I'm sitting here grey and considering coffee as I know I'm not allergic to that... but the YouTube videos look shit and that's stupid right?
Thoughts?
