If you want to change up your look but you’re hesitating, doing a hair donation knowing that it will bring comfort to somebody else might be the motivation that you need. Here at Bored Panda, we found these great before nad after pictures of people who donated their long hair to charities that make wigs for people (often children and young adults) who have lost their hair due to cancer treatment, alopecia areata, and other medical causes. Getting a wig as a gift can bring some security and normalcy to kids who are struggling with losing their hair, and fortunately, hair is a renewable resource that these people had enough of to share.

Hayley Pritchard, a hairdresser from Liverpool, UK, tells Bored Panda that she thinks increased publicity about hair donation encourages more clients to choose that path. “In recent years, people might have a big haircut transformation but wouldn’t initially think about donating that hair. Now, with advertising and word of mouth, it’s much more popular,” she says.

The hairdresser loves seeing positive changes like these firsthand: “As long as the client is well prepared, so far we have always had a very positive response. A long to short hair change is always shocking for everyone, but a few flicks and ruffles of their new beautiful hair, every client so far has always had the biggest smile on their face. With the added bonus they are helping a great cause.”
