The Truth About Why The Dolls in Disney’s ‘it’s a small world’ Have Hair That Grows

I know, I know. This probably sounds like something more befitting of one of Disney’s creepier attractions, like the Haunted Mansion or even the Twilight Zone Tower of Terror over in Hollywood Studios at Walt Disney World Resort. I mean, you don’t really expect to be reading about something as sinister as those charming little dolls that star in one of Disney’s happiest, most beloved boat rides of all time having hair that actually grows, right? And not only does it grow, but it continues to grow each and every year. That is the alarming truth of the matter, and because it is so, it garners that every one of these precious little dolls (and there are around 300 at each Disney Park version of the ride) consistently undergoes a routine “haircut” on an annual basis. This is to ensure that they all remain looking their very best for each 10-minute ride presentation they put on for Disney Guests daily.

How is it even possible? They are just inanimate dolls, right? To better understand the story behind the growing hair, it may be helpful to learn more about the history of the attraction itself and how these dolls actually came into being.

History of Ride Explained

 Before “it’s a small world” ever came to any Disney Park, it was created specifically for New York’s World Fair back in 1964. Originally sponsored by the Pepsi-Cola pavilion, the attraction was created in order to benefit the United Nations Children’s Fund (UNICEF). Walt Disney himself personally oversaw all the details behind this wonderful representation of harmony throughout the world and the idea that children are the same everywhere.

Following a two-season run for “it’s a small world,” the original attraction was brought to Disneyland Park in Anaheim, California. It officially opened to the public there on May 28, 1966. Years after that, the attraction was replicated in order to bring a version of it to Magic Kingdom Park, just in time for the grand opening of Walt Disney World Resort in Orlando, Florida, in 1971. Other Disney Resorts the world over eventually followed suit, and now you will also find existing versions of the “it’s a small world” boat ride at Tokyo Disneyland, Disneyland Park in Paris, and Hong Kong Disneyland.

 How Was It All Assembled?

It’s probably pretty imperative to know just how everything came together for designing this attraction, including how these small, performing animatronic dolls that are so representative of the world’s children were all assembled. That is, after all, where the great mystery lies in them having hair that grows.

Well, as it goes, Walt Disney called on some of his best people in order to help make this attraction come together as perfectly as it did. There were, of course, the Sherman Brothers who wrote the iconic “It’s a Small World (After All)” theme song that gets played more than a thousand times a day.

There were also two remarkable women who were directly involved on a more aesthetic, design-oriented level. You may have heard the name Mary Blair mentioned a time or two. She was known to be one of the Walt Disney Company’s most celebrated artists/designers, with so many projects to her credit. In fact, Walt Disney called on her personally to help come up with the overall details and layout for the attraction back when it was still in the conceptual phases.

Another influential lady whose masterwork as a seamstress for the Walt Disney Company is nothing short of legendary is Alice Davis. She is the one who not only sewed more than 300 costumes for the dolls but also invested a lot of diligence into intricately studying all the different cultures being represented, so as to accurately create the wardrobe with tradition and authenticity in mind.

Okay, So Why Does Their Hair Grow?

Did you ever notice how the dolls showcased within the ride appear to have identical faces? It’s another unifying callout in order to drive home the fact that children are the same everywhere all over the world. It also means that the great detail that went into designing the dolls’ elaborate clothing plays a very important role in assigning their individual identities as representative figures. In addition to their clothing, there are other contributors to differentiating their appearances as well. And this includes the intricately woven hair that’s been so meticulously applied to each one’s head. They always say that hair is what really makes the look, and that’s apparently true, given the fact that it so ingeniously adds personality and distinction to each little character.

But now the big question remains about what exactly the dolls’ hair if made out of that, would continue to grow. Did Disney Imagineering from back in the day incorporate some wacky keratin-infused formula when weaving in each follicle of mystery hair? Or perhaps we’re all actually witnessing some real magic at play. Sadly, that isn’t the case, and the reality is far less mysterious and intriguing than we’d all like to think.

The dolls’ hair actually only consists of yarn. Confusing right? The prospect of yarn growing may seem even more farfetched than actual hair growing, but scientifically it actually does make sense. Because “it’s a small world” is a water ride where Guests float along in gently gliding boats through all the elaborate scenes, and the dolls are all perpetually stationed in their respective locations at all times, things can get a little moist. And that is why upkeep is so important. Combine moisture with an enclosed area, and you get humidity. And it is that humidity that causes the yarn to stretch out over time, often leading to a bit of straggling as well. So, during the routine upkeep, Disney Cast Members have the additional duty of giving these dolls routine haircuts in order to keep their dos intact and looking just as fresh and pristine as ever.

And there you have it, the mystery of why the dolls featured in Disney’s iconic “it’s a small world” attraction all have hair that continues to grow with each passing year. It’s not so creepy after all. In fact, it’s just another way by which Disney delivers on a happily ever after. In this case, however, that happily ever after is solely meant for the dolls.
