OK - some facts on Locks of Love:

They sell a LOT of the hair they get. It doesn't necessarily go into a wig.

They also DO NOT MAKE wigs from human hair for kids with cancer. Only alopecia.

From Wikipedia:
Locks of Love has received criticism for its practice of selling donated hair, rather than using it in wigs as the donors expect. According to a 2003 report by the Better Business Bureau’s Wise Giving Alliance, in 2002 alone Locks of Love had raised over $150,000 by selling donated hair and had received another $213,000 in charitable contributions and grants, but provided only 113 human-hair and 39 synthetic wigs.

Locks of Love representatives are frequent guests on The Oprah Winfrey Show and other daytime television shows, where they provide haircuts to guests and audience members. Though the representatives and show hosts normally suggest that the hair collected during the show will go into a wig, that the wigs are given free of charge to children with cancer, neither of these outcomes are guaranteed

If you want to cut it, cut it. But I WOULD NOT make a donation based upon what they would do with the hair.
