Hair Dryers: The Physics of Rapid Evaporation####Hair Dryers: The Physics of Rapid Evaporation
The invention of the hair dryer has given hairstylists a powerful tool of the trade and the rest of us a quick way to dry soggy fireworks. Check out Groupon?s explanation of the science behind dry hair.
Given time, everything wet?even hair after a long shower?dries due to evaporation. When left to "air dry," hair slowly loses its moisture as the air scoops it up and converts it to water vapor. Hair dryers speed up the drying process by blowing hot air over the wet hair?a process that works wonders thanks to two key principles of evaporation:
Evaporation requires energy, and more energy?in this case, heat?helps break the bonds holding water molecules together more quickly; when those bonds are loose, the water changes states.
A pocket of air can only hold a certain amount of vapor before it becomes saturated. Thus, blowing air over the hair increases the amount of air that can potentially pick up the vapor.
All hair dryers consist of an electric fan and a heating element. As the fan pushes air down the barrel, it passes over the heat and emerges as hot air. Though some models heat coils of wire with an electrical current, others have ceramic heating elements, which can dry hair more quickly by producing the more radiant, safer far-infrared heat. Lately, many stylists have begun to adopt ionic hair dryers, which expel hot air with a surplus of negatively charged ions, reducing static electricity and resulting in smoother hair.
True to their salon's name, stylists at Simply Hair focus their talents on transforming manes with classic salon treatments against the backdrop of maroon and gray walls. The strand pros use Paul Mitchell and Wella products to create looks that flatter individual faces, whether smoothing strands with keratin treatments, adding dimension with highlights, or arranging hair into sweeping updos.
Amid live greenery and plentiful sunlight, Lucia C. Salon's talented stylists prune quick-growing hair into sculpted coifs with the latest cut and color techniques. The crew sinks dry or damaged strands into a helping of reparative conditioning treatments before cutting excess length or straightening curlicues. Their color treatments bless hair with new hues, as quick foil sessions help hair absorb shimmering highlights and patrons practice for school musicals in which they play baked potatoes. In the privacy of a secluded room, the crew wields warm wax to swiftly strip away fuzz from the face and body and infuse skin with a natural-looking glow with the help of airbrush-tanning solutions.
From the sunlight filtering through the window to the highlights radiating from newly styled dos, the interior of Karma Salon & Spa is filled with the brightness that only beauty brings. There, a team of stylists trained in systems by Redken and Pureology beautify hair with ammonia-free color and the Coppola Keratin System. Staffers also rejuvenate skin with Dermalogica facials, resurface faces with exfoliating Jessner peels, and ease muscles with a relaxing hot stone massage.
Perfection in one’s art can be extremely difficulty to achieve. But that doesn't stop the stylists at Shear Perfection by Kristen from trying. As clients sit at hair stations inside the cozy boutique studio, they use scissors, dyes, and straighteners to create styles that best suit each of their guests. As a full-service salon, Shear Perfection also readies brides for their big day with full wedding packages that include styling, a continental breakfast, and tips on how to avoid getting rice stuck to your face.
When it comes to finding the right hair stylist, it's not just their experience that matters, but the type of experience. That's where Mina Floros and Kristin Sarzosa come in. With more than 40 years of styling between them, Mina and Kristin are regulars behind the scenes at Fashion Week in New York, Miami, and L.A. This keeps them on the pulse of trends, as do their continual trainings with renowned product lines Kerastase, Wella, and Arrojo. Amidst the brick and hardwood of their loft space, Lounge Hair Studio, they apply their hands-on experience to clients via cuts, highlights, and keratin treatments, the last of which pumps protein into hair more effectively than feeding it hamburgers.
