You may suffer all of the following but it is most common to just notice one or two of the symptoms. Like other forms of contact dermatitis repeated exposure may cause the allergy to develop therefore alternatives to permanent hair dye should be researched as soon as an allergy is confirmed.

Itching scalp/skin

Redness

Swelling

Mild dandruff like symptoms

Scaly skin

Pain

Sneezing or other hay fever/cold like symptoms when ever hair dye applied

Nausea when dye applied

Sever swelling around eyes

Scaly skin on ears, face and neck

There have been two deaths attributed to anaphylaxis due to hair dye. This sever allergic reaction is incredibly rare but stands to show how serious and allergic reaction can be. Even if you have been using a product for years a patch test should always be applied and the developer (oxidizing agent) should always be mixed with the dye or tint for this type of test.

Hope I helped and not just scared you.

its probly got nothing to do with the hair dye,
cus my sisters got a recaction to hair dye,
and all she gets is a icty and flakey scalp,
its most probly something else.

Some times dye will give you a rash almost like sunburn the skin will flake and scab it will be extreamly sore for a few days.

my mom is sensitive to hair dyes but she only gets itchy and flaky scalp whenever she colors her hair

Not the symptoms you describe!

i dont think what you mensioned are symptoms of an allergic reaction to hair dye you may have somthing else you should see doctor.
