My friend's client had a bad allergic reaction to hair dye yesterday

Always do a patch test before coloring to prevent scary situations.

Was the reaction immediate or did it take time to develop? Delayed responses like Brooke mentioned can trick you into thinking you're safe. That's why a full 48-hour patch test is non-negotiable for me.

Reactions can be delayed a full day sometimes.
