I have been coloring my hair for 12 years to cover the gray. Suddenly I have developed a severe allergy to the haircolor that I always use. I am talking blisters on my scalp , my forehead swelled , my eyes were swollen shut , and a bad rash on my neck. I only brands of color I used are Bigen or Waterworks in a black shade. I My hair is very long and I have always gotten excellent results with these brands. My questions are: Are your products similar to Bigen and waterworks? Could I use the Eco Colors over Bigen?
