8 Vintage Hairstyling Products Your Grandmother Probably Swore By

“Natural” beauty has become a lot less time-consuming (and painful) thanks to technology. Women can easily shampoo, dry, and style their hair; those with straight hair can achieve curls in a matter of minutes. That’s not how it used to be—some of us remember when slumber parties were spent setting our hair in rollers or pin curls while simultaneously playing Truth or Dare. If you’re a Baby Boomer or a bit beyond, these products may bring back some not-so-fond memories.

1. DIPPITY-DO

 
Dippity-do was something of a prehistoric styling gel: It wasn’t as lightweight as the current products, and it didn’t contain today’s trendy ingredients like aloe and wheat protein. The original variety had the consistency of Jell-O and was designed to hold a set longer (when used with hair rollers) or to plaster bangs and fly-away hairs in place. (As a teen, KISS drummer Eric Carr slathered his hair with the stuff nightly and slept with a nylon stocking over his scalp in an effort to tame his natural curls into a Beatle-esque mop top.) Dippity-do could even be used on dry hair to set it in between shampoos—for some reason, beauty advice columns of the 1960s vehemently admonished ladies against washing their hair more than once per week.

2. CRÈME RINSE

 

Some older folks use the terms “conditioner” and “crème rinse” interchangeably, just like grandma used to do with “ice box” and “refrigerator,” but there is a difference between the two products. Crème rinse is much thinner in consistency because it doesn’t contain the emollients and sunscreens typically found in conditioner. The main purpose of crème rinse is to detangle hair and reduce static electricity. In the 1950s and '60s, crème rinse was one of those luxurious “extras” that was mostly used by older women, not children or teens. That’s why so many of us have painful memories of mom tugging a comb through our tangled wet hair after every shampoo, and muttering “beauty must suffer” whenever we dared to complain.

3. ELECTRIC ROLLERS

 

Children are little sponges, absorbing an amazing amount of information at a young age. Sometimes that’s a good thing, giving them a definite leg up once their formal schooling begins. Other times it can be an embarrassment for the hapless parent—like when her child sings out in clarion tones, “Curlers in your hair, shame on you!” to a stranger in the checkout line at the supermarket. Even though it was considered gauche to go out in public with rollers in your hair, many busy housewives simply tied a scarf around their head in an attempt to cover their rollers and went about their daily errands hoping that their hair would be dry in time for the evening. In the late 1960s Clairol took a step forward in protecting the American public’s eyes from unsightly head hardware by introducing Kindness, a revolutionary set of electric rollers that gave you a head full of curls in about 20 minutes or so. The rollers took 10 minutes to heat up, and they weren’t as insulated as today’s models are, so tiny foam wedges were provided to place between your scalp and the hot curler (burned fingers were just a hazard of instant, or semi-instant, beauty).

4. BRUSH ROLLERS

We’ve all heard stories about the virginal brides of the 1940s and '50s who, despite the stilted “talk” Mother gave them prior to walking down the aisle, were shocked and/or horrified at what actually occurred on their wedding night. Much less has been recorded from the husband’s point of view: the shocking tableau presented the first time his new wife emerged from the bathroom sans makeup and with her head encased in what looked like barbed wire. Hair dryers were mainly found only in beauty shops, so to get that naturally curly look that would last in between shampoos, women routinely wound their hair in brush rollers before retiring for the night. Finding a comfortable sleeping position while wearing them was something of an art form.

5. ORANGE JUICE CAN ROLLERS

Lady Gaga may have appeared to be a trendsetter when she set her hair with pop cans (or soda cans if you prefer), but women were actually using can technology 50-some years ago. Back when beehive or bouffant hairdos with a maximum of pouf were all the rage, girls cursed with straight hair used rinsed-out cans of frozen orange juice concentrate (with both ends cut out) as makeshift jumbo hair rollers. On the other end of the hair spectrum, girls blessed with naturally curly hair set their hair with cans to flatten their tresses into that straight California surfer-girl look. Keep in mind that blow dryers were not yet commonplace, so—like their brush roller sisters—women often had to sleep with their hair rolled thusly.

6. BONNET HAIR DRYERS

 

Part of the reason women subjected themselves to nightly sleeping-with-rollers-in-their-hair torture was that prior to the mid-1970s there really wasn’t a more time-efficient way to dry one’s hair. There were a few primitive hand-held blow dryers available beginning in the 1920s, but they weighed an average of two pounds, were insulated with asbestos, and only produced a paltry 100 watts of heat. In 1951 General Electric introduced a portable soft-bonnet hair dryer, which was a home version (sort of) of the hard-shell blast furnace dryers that beauty parlors then used. The plastic cap was flexible enough to fit over a head full of rollers, and the “works” part (the motor, etc.) was supposedly light enough to carry around (via a convenient shoulder strap) as the busy housewife attended to her regular daily chores. It was quite the innovation when bonnet dryers with the power to dry hair in just 22 minutes eventually hit the market.

7. HOME PERMANENTS

 

Toni introduced the home permanent in the late 1940s, and the product flew off the supermarket shelves into the homes of women who wanted to save the cost of a salon wave. Other brands like Lilt and Rave followed, but thanks to an aggressive, long-running ad campaign (“Which twin has the Toni?”) “Toni” became as synonymous with a home perm as “Kleenex” did with facial tissue. Suddenly every mom became a kitchen table hairdresser, completely ignoring the fact that there’s a good reason it takes many months of study for a stylist to become licensed. As a result, many young girls of the 1950s dreaded those special times of year—back to school, Easter—when Mom decided that it was “time to give you a Toni.”

8. AEROSOL HAIRSPRAY

 

That hole in the ozone layer we hear so much about? I’m loathe to point fingers, but I have a feeling the elaborate bouffants and flips of the 1960s had something to do with it. Mary Tyler Moore admitted that her Dick Van Dyke Show on-set stylist sprayed her flip so solidly that “you could hang clothes on it,” and Barry Williams (of Brady Bunch fame) reminisced in his autobiography about a guest spot on That Girl in which Marlo Thomas spent every off-camera moment having her hair teased and sprayed until it could deflect bullets. As mentioned earlier, shampooing more than once per week was out of the question, so when a lady’s hairdo started to go limp, it was hairspray to the rescue. Women moistened their hair with Aquanet, White Rain, or VO5 before re-setting it with rollers or giant clips. Those cans were filled with fluorocarbons as well as the other ingredients that lacquered hair into submission, and people spritzed that stuff with abandon until the FDA stepped in and hair styles gradually changed to a more “natural” look.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

What Happened to Jamie and Aurelia From Love Actually?
May 26, 2017

Fans of the romantic-comedy Love Actually recently got a bonus reunion in the form of Red Nose Day Actually, a short charity special that gave audiences a peek at where their favorite characters ended up almost 15 years later.

One of the most improbable pairings from the original film was between Jamie (Colin Firth) and Aurelia (Lúcia Moniz), who fell in love despite almost no shared vocabulary. Jamie is English, and Aurelia is Portuguese, and they know just enough of each other’s native tongues for Jamie to propose and Aurelia to accept.

A decade and a half on, they have both improved their knowledge of each other’s languages—if not perfectly, in Jamie’s case. But apparently, their love is much stronger than his grasp on Portuguese grammar, because they’ve got three bilingual kids and another on the way. (And still enjoy having important romantic moments in the car.)

In 2015, Love Actually script editor Emma Freud revealed via Twitter what happened between Karen and Harry (Emma Thompson and Alan Rickman, who passed away last year). Most of the other couples get happy endings in the short—even if Hugh Grant's character hasn't gotten any better at dancing.
