Hi everyone,

5-6 weeks ago I purchased a red hair dye from the L'Oreal Preference line. It came with a bottle that is to be used 2-3 weeks after colouring for a touch-up. I didn't do a skin test with this product because I've used this line in the past and I assumed that there would be no reaction. I didn't have a reaction to the actual hair dye itself (which I used immediately after purchasing), but I used the touch-up and had a reaction within a few hours - itchy scalp and hairline at first, which then developed into hives everywhere the next day.

My question is: how long will this reaction last? I used the touch-up 8-9 days ago and I still have hives. I think I've been seeing some slight improvements over the last few days but I've never had an allergy that's lasted longer than a day or two so I'm not too sure what to look for.

I've already gone to the doctor (around the 3rd or 4th day into the reaction) and I was told to just keep taking Benadryl and power through it but she didn't give me an estimate as to how long it'll last.

Hope this isn't a silly question. I work in a warehouse and although the allergy is not horrendously painful, it is a bit of a nuisance when I'm constantly scratching or rubbing against cardboard and wood. I'm just really hoping it will calm down soon.

Thank you!

EDIT: I thought I was seeing improvements, but shortly after posting this, I noticed something. My hives, which previously had just been red, itchy patches, are now swelling. Actually, even if I scratch my skin (a non-hive area), it will still swell. I washed my face and my one eyelid got a little bit puffy. Not sure what's happening here, I'm assuming this is a step backward though.

If anyone has any answers that might help me, please comment. I'm becoming more and more frustrated everyday.

Did you go to your PCP or an allergist? I would go to an allergist even if you've already seen one. It seems a bit long for this reaction to be going on, and especially if it's getting worse.

The doctor may put you on prednisone or prescribe something topical to relieve the itching. Make sure you take along your list of any medicines or foods or chemical allergies and a list of whatever was in the dye.

Find out ALL the ingredients in the dye. Check them against any dye you've used before without having a reaction. Call the dye company if you have to. If you don't have the box, look it up online.

Stop dying your hair. What would you do if the next time all your hair fell out? I let my hair go gray and I like it now. People open doors for me and let me merge into traffic.

I agree with Alcie, stop dying your hair, you have had a terrible reaction!!

I have Multiple Chemical Sensitivity which is no fun, and through my research on this condition, hair dying (especially with the strong chemicals that they use) is just one of the ways you can end up with worse problems in the future, (like MCS).

Taking Methotrexate 10mg weekly and on 10g of Prednisone at the moment, hoping it will work for me.
