The basic difference between Avigal Henna and other hennas on the market is that Avigal Henna is 100% pure henna made from the finest quality henna available. Avigal Henna is the safest and most effective way to color and condition the hair. Simply add hot water to the henna powder, mix well and apply. Follow the time specified on the enclosed instruction sheet. If you use an external heat source, you can cut the processing time by 30%.

PERMED HAIR? You can apply Avigal Henna over permed hair without worry. In fact, Avigal Henna will lock in the perm, making the curl last longer. If you want to perm after a henna application, perm as usual and then reapply henna since the chemicals in the perm will strip the henna color from the hair.

GREY HAIR? Avigal Henna has developed 6 shades for single process use on grey hair: Natural, Hazel, Topaz, Champagne, Strawberry Blonde and Red. Each may be applied directly onto grey or graying hair for highlights ranging from extraordinary shine to rich red. Grey hair can also be darkened by the double process method.
