The strength of a football player's grip can make the difference between landing the winning points and losing the game, so there's a lot riding on the ability of players to keep their hands in top shape. But training can only go so far. In reality, the skin on players' hands get worn down the more they handle the pigskin, barrel through the defense, or hold back the offense, especially in extreme weather conditions. So, for the players on at least 10 NFL teams, part of keeping their hands ready to catch that winning pass includes the nourishing effects of Jack Black Industrial Strength Hand Healer, which is now available in specially co-branded versions in the locker rooms of the San Francisco 49ers, the Dallas Cowboys, the Chicago Bears, and the Seattle Seahawks, among others.

"Football players' hands take a heavy beating during workouts and on the field. Cuticles and nails get damaged from all the grabbing and pushing. Players develop callouses, irritations, and chapping," says Jack Black co-founder Jeff Dandurand. The Hand Healer uses the reparative power of macadamia nut oil and glycerin, both of which are magic bullet ingredients that fix up these issues, and tackle a few others as well. "Hands have the fewest and smallest oil glands in the body so they tend to get much drier than the rest of our skin," Dandurand adds. Meaning they heal a lot slower. Besides the oil and glycerin, vitamins A and E are added to the Hand Healer to bolster and develop skin cells' internal strength over time, and natural antiseptic eucalyptus oil keeps bacteria at bay.

Formulations and functions aside, we like these ingredients because they do the work of a juggernaut quarterback, but go on light, absorb quickly, and don't at all feel greasy. Plus, there's little more than a slight menthol scent, which keeps it nice and stealth.

"Our first partnership was with the Dallas Cowboys over three years ago," Dandurand says. "Word of mouth spread and the following year we had partnerships with the Green Bay Packers, Washington Redskins, San Francisco 49ers, Seattle Seahawks, and the Chicago Bears." This year Jack Black has added the Denver Broncos, Atlanta Falcons, and New York Jets to the list of teams using its powerful hand cream. Jack Black's eyes are set firmly on another team sport that relies heavily on the condition of player's palms – basketball. Starting this year, the company has already teamed up with the Miami Heat and Dallas Mavericks. While the co-branded versions of the product aren't available to the public due to licensing reasons, the standard Jack Black Industrial Strength Hand Healer is the same exact stuff and will take care of your hands every bit as nicely.
