Have you ever wondered what happens when you donate your hair to charity? What’s the process it does through? Who does the hair go to? This BuzzFeed video has all the answers you’re looking for. It also makes us all warm and fuzzy inside. This is what the process of donating hair, from start to happy finish, looks like.

First, of course, the hair is donated by upstanding people like you! In this instance, we’re following Hannah, a young woman who is donating her hair to Wigs for Kids. Your hair has to be a certain length to donate to most charities, usually 10-12 inches has to be cut off, and it’s usually done is ponytail sections.

But once you leave with your fresh new ‘do, the hair you’ve left behind goes on a pretty amazing journey.

The next step is to have the hair sorted into colors and vetted; not all hair is going to meet the standards for all charities, so locks that don’t make the cut are filtered out. Usable hair is then sent along to the wig manufacturer.

Making wigs is an art that’s been around for centuries, so it’s not as cut and dry as you might think. The hair has to be brushed, the shorter pieces have to be removed, the ponytails have to be sewn together, the strands must be treated to a chemical bath, and that doesn’t even begin to cover the making of each unique wig cap. A few different shades of hair are usually combined into one wig to give it a natural look and then the wig is sewn onto the cap one hair at a time.

After this tedious process, the wigs are complete and go on to their final destination: their new owners. And this is where to magic really happens.

Hannah’s hair (as well as the hair of 20-30 others) was used to make a wig for a little girl named Bridget. Bridget has alopecia, which has caused her to lose her hair very young. It’s wigs like this one that make her feel, well, normal. Her mom sums it up better than anyone:

“It might not seem like a lot in the big scheme of things, but to a little girl it means a whole lot. So I really have to thank the people who donated.”

You can tell the difference it makes just by watching Bridget’s face. She looks transfixed on her new wig and we can’t help but grin has she brushes and plays with her lovely new hair piece. This type of donation, as trivial as it might seem to some, changes lives every single day.
