A member asked:

I used a little bit of hair dye and now half my head is swollen. it's been three days already.how long before it subsides?

A doctor has provided 1 answer

Allergy to dye: You have developed a contact allergy to the hair dye, you need to see a doctor to prescribe to you medications to calm the inflammation down. Don't neglect this, you may lose hair if untreated.
