Talk about the true definition of friendship! Tyler Boone of Tampa Bay grew his hair out for two full years so that he could donate it to his friend Gabby Rulz, who has alopecia - a disorder that causes her to lose her hair.

He told the local news station that he just wanted to make her "happy." And, before the end of last year, Gabby was able to cut 12 inches of Tyler's hair off through an organization called Children with Hair Loss.

Can you imagine how hard this must've been for Tyler? What an amazing thing to do for a friend!
