Although it is a process that requires much time and patience, it is possible to dye black hair blonde with the proper technique. A salon professional can achieve better results than a home dye job.
According to Laura Kiorkis, the owner and operator of Gemini of Chicago Hair Salon in Peoria, Ariz., stylists can dye dark hair to a shade of blonde by using one of two techniques. The first technique involves stripping the color from the hair using a soap cap. The second technique requires lifting the hair to a lighter color by applying an ammonia-based color onto uncolored hair. The technique used depends on the state of the client's hair. Dying dark hair to any shade of blonde can be very damaging if bleach is used. Usually this type of dye job requires two appointments if the client wants to have a light blonde result. The intermediate step is typically a yellow-orange hair color.
