Even athletes can't escape genetics.
When these guys finish their playing days, announce their retirement, or finally come back to reality, a friendly text from representatives at Rogaine may be the first thing they see.
These athletes have mastered their respective sports, all the while wearing headbands, shaving their face and continuing on to their scalp, or rocking it without shame.
No matter how they chose to deal with it, they can't escape this countdown! We proudly give you,
Pete Sampras and the Worst Receding Hairlines in Sports.

If you're ever wondering if an NBA player is balding, track the headband.
LeBron James and Baron Davis are certainly not the first players in NBA history to come up with the "Headband-Makes-Me-Feel-Comfortable" strategy.
Baron Davis unfortunately followed in Donovan McNabb's footsteps and tried to offset it with the full beard.
Now he just looks like a Los Angeles sandwich snatcher living behind Subway.
"Big Daddy Vlad" used to keep his hair trim with the Montreal Expos, but it wasn't long after he appeared in the Home Run Derby in an ugly orange jersey and dreads that we realized that orange jersey wasn't the ugliest thing attached to his body.
Dreads can't hide your hairline, Vladi! Just embrace the bald!
Rooney, an English footballer, is considered one of the most outspoken players in the league.
Everyone has heard of Little Man Syndrome, but what happens when someone is insecure about their hairline? Do they call it Crop Shrinking Syndrome?
Okay, so it wasn't great, but I had to take a stab at it.
The world champion surfer doesn't have time to be slowed down in the water by a head full of hair...
At least that's the excuse he goes with for shaving his remaining locks off in favor of the cueball look.
I know what you are thinking, and yes, we count the WWF/E as a sport, even if it's only for the sake of this countdown.
Do a quick Google search of Angle and you'll soon find pics of him with a full head of hair. Ok, a semi-full head of hair.
Anyways, check him out now. Looks like a dolphin struggling out of the grasp of a Killer Whale, right?
That's what I was thinking!
No, really, it is, you just can't see it because he wears that mask after breaking his face earlier.
He keeps it shorter now so you can't tell. Wise move, Rip.
While later in his career with the Oakland Raiders, Rice must have been going through a mid-life crisis and got caught on camera without his helmet on WAY too many times.
This shot makes him look like he was wearing a flesh-colored bandanna.
Maybe the pressure and stress of announcing your new team in an interview on national television would cause someone to pull out their hair.
Maybe the thought of underachieving while having plenty of star power around you would be so great, it would cause your hair to fall out.
Maybe making excuses for LeBron James' hair loss will result in having my jersey burned...After all, nothing is scarier than a jilted lover on a rampage.
Don't believe me? Just watch video of Heat vs. Cavs, 12/02/2010.
Like we mentioned with LeBron James, STRESS. I'm sure if Tiger is reading this, he doesn't care.
One of the most embarrassing parts of losing hair is knowing the ladies are moving to greener pastures. In Tiger's case, they love the desert.
Grew the Afro...NOPE, that didn't work. Grew the long sideburns...Who are you kidding? Grew the goatee...Just stop, really, now you're just embarrassing yourself.
You know what Donovan, just keep your helmet on. There's no need to draw further attention to the failure you're becoming in Washington after being booted for the former ringleader of a dog fighting league.
Too much, too soon? Nah...
The Los Angeles Galaxy forward has been showing the world that receding, curly hair can still be cool while rocking short white shorts and winning an Oscar for flopping after being sneezed on.
It was a sparsely reported story years ago, but when teammates decided to put acid in Hasselbeck's helmet as a joke, it drastically altered his future, forever.
In related news, it also gave him a white upper lip and I completely made this up.
Has Matt Holliday confessed to using steroids yet? Because his head is looking just like Barry Bonds', only in a lighter shade.
Is the hair-loss thing related? I need answers...
See what I mean?
Put it back on! Put it back on!
On a more serious note, I think a player of this size should be allowed to have a receding hairline. I'm totally not speaking out of fear, either.
The Dallas Mavericks PF has been in hair-loss denial for years, dating back to his early days with the Minnesota Timberwolves.
Not that anyone notices him, now that he's on the Mavericks bench, but at least have the decency to stop blinding fans who paid good money for seats close to the court.
How are they supposed to watch the game when that reflection like sun off a windshield is blinding them?
Kevin Youkilis also dons the Fu Manchu from time to time. Here he is with the full goatee.
However, his hairline amazingly doesn't grow as fast as his facial hair. Talk about a dichotomy of root placement.
See? I can talk smart too!
I spared you the photo of the back of his head: It looks like Ginobili is the newest victim of Johnny Knoxville's sneak buzzer attacks.
Ginobili probably has the most dominant bald spot on the countdown. He is currently letting his hair grow out, so try not to snicker when the Spurs are celebrating a championship and his hat gets knocked off.
You can chart Sampras' career based on how much hair is on his head, from his first Grand Slam at the U.S. Open in 1990, to doubles matches with Roger Federer.
There are many photos out there of Andre Agassi and his '80s hair disaster. These days he keeps his head hair trimmed more closely than his chest hair, as evident in this photo.
Agassi made his balding head famous, before leaving tennis professionally for non-Hair Club for Men related reasons.
