Not hair per se, but there's at least three people who I recognize on account of the fact they always go for a horse mask. Granted, I mostly recognize them as 'one of those guys wot keeps trying to make the horse mask their thing'. Sadly, I have yet to witness a battle royale to establish the true claimant to equine royalty.
