Depp wears a dreadlock wig in a rock-and-roll approach to a pirate aesthetic. He wears a red bandanna and numerous objects in his hair, influenced by Keith Richards' habit of collecting souvenirs from his travels; Sparrow's decorations include his "piece of eight". Sparrow wears kohl around his eyes, which was inspired by Depp's study of nomads, whom he compared to pirates, and he wore contacts that acted as sunglasses. Sparrow has several gold teeth, two of which belong to Depp, although they were applied during filming. Depp initially forgot to have them removed after shooting "The Curse of the Black Pearl", and wore them throughout the shooting of the sequels. Like all aspects of Depp's performance, Disney initially expressed great concern over Depp's teeth. Sparrow wears his goatee in two braids. Initially wire was used in them, but the wires were abandoned because they made the braids stick up when Depp lay down. Sparrow has numerous tattoos, and has been branded a pirate on his right arm by Cutler Beckett, underneath a tattoo of a sparrow.
