Create the illusion of long, thick hair by using black bump comb hair accessories to lift and shape your hair and reduce damage to your hair too!. A 9cm black bump comb will remove the need for back combing and all the associated snagging and damage caused. These bump combs are invaluable accessories when used correctly. Simply slide the comb into the area you want to lift and pin hair over it to conceal. Finish with some flowers or crystal pins and no-one will know it isn't all your own hair.
