Hi Doctor, I have recently got my hair colored post which I have observed lots of acne / boils appearing majorly on my neck, below ears, in and around nose area. I generally have a healthy skin and never had such a problem before. I believe this may be due to some reaction / allergy I might have from the colour or chemicals present in the color. Though its been 4 weeks but still the problem remains. Wanted to know how long suh reactions persists and do I need to take any medicine. I do not intend to use color in future as the problem may reoccur.
