The tail comb is helping to ensure an even spread of dye through the hair after application. The metal pin tail comb is perfect for separating section of hair prior to dyeing or bleaching hair extensions. Its fine teeth help to release knots for a better overall look and feel. Always use a sectioning comb to place your parting. This will ensure it is straight from your hairline to your crown. You can try sectioning hair properly before styling, and blow drying, to create a more professional, longer lasting style. Comb length 22.5cm, comb width 2.8cm, comb thickness 0.4cm.
