Alli Hemp said she had planned to shave her head late last year as a "fun adventure" -- and then decided to turn it into something with more meaning.
The Hauppauge High School senior raised more than $2,100 this winter through a head-shaving fundraiser to benefit The St. Baldrick's Foundation, a childhood cancer charity.
She had 17 inches of her hair cut off, while eight other friends and family members — including her grandmother Helen, 75 — shaved their heads for the cause as well.
The money collected went to St. Baldrick's, and the hair went to Pantene Beautiful Lengths, a charity campaign that provides free real-hair wigs to women who are fighting cancer.
"I was really stunned by the amount raised," said Hemp, 17, who said her goal was $1,000.
Of her new hairdo, she said: "It's taken a bit of getting used to, but I know how much of a difference it makes to people battling cancer. They lose their hair willingly and are dealing with something much worse."
To raise the money, Hemp sold nearly 250 bracelets for $1 apiece and solicited donations from family and friends.
She is a member of her school's swim team, the German Honor Society, the women's choir and vocal jazz ensemble.
