BLONDOR by ellis hair group

The Wella Blondor lightening system is an effective hair bleaching and coloring kit. It can be used to touch up dark roots, lighten an entire head of hair, create streaks or just lighten hair tips for contrast. The Wella Blondor system comes with a reactive bleaching powder and a blonde color, but the grade of lightness is dependent on the developer you use. Developer is actually peroxide and comes in grades ranging from 10 to 40. The higher the developer number, the lighter the hair will become.
