We all know home haircolor can be bad for your hair, but deadly too! This teen experienced a terrible allergic reation to the product. Box color contains 23% ammonia and windex has 12%, most professional color has from 1% to 3%, BIG DIFFERENCE! No wonder people that continually color at home have very dry, dull, lifeless hair, not to mention not always a desired color! Even if times are tough leave the haircolor to your professionals! PLEASE! Many Salons my self included have some quick and less expensive ways to brighten up any haircolor just ask your stylist!
