Every sport has its iconic hairstyle. Hockey has its mullets, basketball has its flattops, or in the case of long-time NBA power forward, Dennis Rodman, every hair color and style imaginable.
 
And of course, lacrosse has its flow.
 
Flow, as defined by UrbanDictionary.com, is "hair that would flow out the back of someone's helmet and curl up around back of the helmet." Flow, and longer hair in general, are so popular in the sport that Inside Lacrosse has produced All-Flow Teams in the past, highlighting some of the best hair in college lacrosse.
 
One member of the Towson University men's lacrosse team has taken his flow to extreme lengths, but not just for trendy looks under the helmet.
 
Freshman defensive midfielder Jackson Mumford has been growing his hair out for over two years and has a thick crop of lettuce pouring out of his helmet. Mumford has been growing out his flow to benefit Wigs For Kids.
 
Wigs For Kids is an organization that creates wigs from donated hair for kids under the age of 18. While there are several groups around the country, Wigs For Kids benefits all kids who have undergone hair loss, whether from chemotherapy, burn victims, and others.
 
"I thought it would be honorable to donate my hair to kids," said Mumford. "I hope having a wig will help them gain some confidence."
 
According to WigsForKids.org, the change in a child's appearance "can drastically undermine their self-image and sabotage their self esteem." Wigs For Kids, founded by certified cosmetic therapist Jeffery Paul, has been serving children suffering from hair loss since 1981.
 
Of course, the hair must meet minimum standards to be donated. Hair must be at least 12 inches in length while in a ponytail, cannot be chemically or color treated, nor will dreadlocks be accepted.
 
The length minimum won't be a problem for Mumford, whose hair currently hangs down near the middle of his back from under his helmet. Mumford will likely continue to grow out his hair through the end of the 2016 season or possibly to midsummer.

A long-time activist in his community, Mumford first got the idea to start growing his hair out for Wigs For Kids, while his mother, Fuzzy, was the cancer care navigator at Atlantic General Hospital in his hometown of Berlin, Maryland.
 
Mumford has participated in several 5k races for charities and has worked as a camp counselor while playing his high school ball at Stephen Decatur High School near Ocean City, Maryland.
 
When the demands of high school academic and athletics, followed by heading to Towson, Mumford found a little less time for community service. He figured growing his hair would be an easy way to continue with the demands of college and still be able to give back.
 
"I had the typical prep school kind of hair cut, over the ears, off the collar kind of hair," continued Mumford. "I went from that to what I have now, pretty far down my back.
 
"I have the time, so why not grow it out? And that's what I've been doing. … I thought it was a great way to give back to someone less fortunate than I am. I've been blessed with a lot of gifts, like being at Towson, and I thought it was an easy way to give back to somebody who really needed it."
 
Mumford has not cut his hair in over two years, when he was a junior in high school, and has not even trimmed it.
 
"I challenge others to donate their hair because it takes various contributions of hair to make one wig," Mumford said.
 
So when you see the mane coming out of Mumford's Towson lacrosse helmet, just go with the flow.
