High density boar bristles makes this THE top brush for gloss and body. The natural boar bristles are "bushier" than those of the G-Series brush grabbing on to hair for longer/tighter and creating incredible shine and volume as it brushes through the hair. Allow 3cm clearance between the dryer nozzle and the brush to allow hot air to blast through the brush & circulate around the hair for effective drying without heat damage.  Extra tension created on this brush makes it ideal for medium to thick hair.
