Teenage girl sprays hairspray... boy says that her hair feels like chewing gum. Wanda the Witch appears, waves her wand and fixes the problem... Hidden Magic, "The Problem Solving Hairspray".
Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Hair spray (also hair lacquer or spritz) is a common cosmetic hairstyling product that is sprayed onto hair to protect against humidity and wind. Hair sprays typically consist of several components for the hair as well as a propellant...
Hair spray are a blend of polymers that provide structural support to hair. These frequently include copolymers of polyvinylpyrrolidone (PVP) and polyvinyl acetate (PVAc). Vinyl acetate-crotonic acid copolymers give harder films. In this way hairsprays can be formulated as flexible, medium, and maximum hold. The copolymer mixture is usually adjusted to achieve the desired physical properties (adhesive strength, foaming, etc.), using plasticizers such as aminomethyl propanol, surfactants such as benzalkonium chloride, and other agents like dimethicone.
Since the phase-out of CFCs in the 1980s, hydrocarbons are popular propellants. These include propane, butane, isobutane, and related volatile hydrocarbons, as well as other mixtures. Such hydrocarbons are poor solvents for the active ingredients such as the polymers. For this reason dimethyl ether is often added as well. It functions both as a propellant and a solvent.
Plasticizers used in hair spray include esters of citric acid and adipic acid. Silicones and polyglycols are also used.
The concentrate comprises only a small volume of a can of hairspray. Most of a canister is filled solvents such as isopropanol (rubbing alcohol) and ethanol...
Early hair sprays were developed in Europe in the 1920s. In the US, hair sprays were developed around the time of the aerosol can in the 1940s, and the first patents describing copolymers for hair styling were published in the 1940s.
In the US, the first to package it was Chase products (an aerosol manufacturer) in 1948, as the beauty industry saw that the aerosol cans used in World War II for insecticides could be used as a dispenser for hairspray. It thrived and became increasingly popular and mass-produced, as updos and other such hairstyles were created. By 1964, it became the highest selling beauty product on the market.
In 1968 at the feminist Miss America protest, protestors symbolically threw a number of feminine products into a "Freedom Trash Can." These included hairspray, which was among items the protestors called "instruments of female torture" and accouterments of what they perceived to be enforced femininity.
Sales of hairspray declined in the 1970s as hairstyles became predominately worn straight and loose. By the 1980s, hairspray’s popularity came back as big hairstyles resurged with the glam metal scene.
Prior to 1979, the most popular propellants in hairsprays were CFCs. Owing to environmental concerns, they were replaced.
