The New York Times has a story about charities such as Locks of Love, which makes wigs for kids suffering from hair loss for medical reasons. The actress Diane Lane cut her hair for Locks of Love on live television. It’s all the rage to get haircuts to help “kids with cancer,” though as the charity’s website explains, most of the hairpieces go to kids with alopecia areata.
The Times reports, “As much as 80 percent of the hair donated to Locks of Love, the best known of the charities, is unusable for its wigs, the group says. … Even hair that survives the winnowing may not go to the gravely ill, but may be sold to help pay for charities’ organizational costs.” The wigmaker then rejects about half of the remaining hair.
To put it baldly: If you want to make a drastic hair change, do it for yourself. You’re probably the only person who is going to benefit. If you insist on cutting it for a higher purpose, read the Locks of Love FAQ first.
