Lucha Libre match in history. A close transcendental for mask bets in history is the family feud between Ray Mendoza's sons against Shadito Cruz's sons, which lead in 1988 to a triple mask beat between Villano I, Villano IV and Villano V versus El Brazo, Brazo de Oro (wrestler) and Brazo de Plata, with the Villanos winning the masks of the Alvarado brothers. Máscara contra cabellera ("mask versus hair"): a masked wrestler and an unmasked one compete, sometimes after the unmasked one has lost his mask to the masked one in a prior bout. If the masked luchador wins, the unmasked one shaves his head as a sign of humiliation. If the unmasked luchador is the winner, he keeps his hair and the loser is unmasked. These kinds of matches are not so frequent since, since masked wrestlers usually are reluctant to beat their masks against hair. This is because masks are a more appreciated trophy than hair, and masked wrestlers had more on the line than unmasked ones (often unmasking results in a decrease in popularity for the wrestler, also, a masked wrestler usually lost his mask just once, while unmasked wrestlers can get shaved many times). Most often the result is the masked wrestler winning the hair of the unmasked one. But there are examples when the opposite result happens. The Perro Aguayo (father) was a wrestler that never adopted a masked gimmick and was very successful in bet matches, unmasking important wrestlers like Konnan, Máscara Año 2000 and Stuka (father). Aguayo's hair was a trophy so coveted by legends El Solitario, El Santo, and Villano III they bet their masks to win it. Another important hair was from Cavernario Galindo, a legendary unmasked wrestler from the golden age of Mexican Lucha Libre, a case similar to Aguayo's, he never wrestled masked. And although Galindo never win a mask, he was respected enough that the two most important wrestlers in Mexican history, El Santo and Blue Demon, risked their identities to win Galindo's hair. Cabellera contra cabellera ("hair versus hair"): the loser of the match has his head shaved bald. This can occur between both unmasked and masked wrestlers who have to remove their masks enough to be shaved after the match. These matches are very common and are far from the interest and expectation the masks bets have. But still, there are some wrestlers that went noticed
