Can I use a hair dye tube that I opened one month ago?

[tilda0]

Hi all,
I opened my hair dye around one month ago to do the allergy test behind the ear. I ended up not using the box. The colour tube is open though. Is it safe to use it? Am I taking a risk? Thanks for tips

Oh my god I was just going to post if it was ok to use a hair dye I mixed with the developer creme on Friday from a box dye!

We should be more organised and use things at the time!

I haven't mixed it though! SnipSnipMrBurgess ;)
Let see what MN beauty gurus advise! Hopefully someone can help.

Unmixed one I would use, mixed one I would not use

tilda can probably use hers I frequently mix half a tube to do my roots and then leave the rest for next time.

snip once mixed I think it has to be used or discarded, but no clue the effects of leaving for 2 days, sounds like a science experiment......

Unmixed definitely. Mixed no.
