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.
Upon first glance, Eutopia Beauty Studio appears a classic, modern salon, thanks to its earth-toned walls, spacious leather sofa facing a flat-screen TV, and shelves lined with products by Milk_shake, No Inhibitions, Keratin Complex, Malibu, and Brocato. However, the styling area brings a hint of Old World class to the modern space. Cherry-wood cabinets outfitted with clean marble countertops and elegant metal hardware jut from a rustic brick wall. Here, stylists twirl around black, boxy styling chairs as they ribbon hair with highlights and snip off split ends. They treat parched strands to deep moisturizing treatments, and retexturize locks with relaxers, permanent waves, and keratin smoothing systems. Once hair is done, makeup artists take over and gussy up features with false lashes and full makeup applications.
Paradiso Salon's full-service beauty boutique has been pampering patrons from head to toe for more than 21 years. Amid charming wall sconces, an ornate chandelier, and full-length mirrors, hairstylists fashion custom 'dos with precise cuts and color treatments, wielding organic Surface products. Plush reclining mani-pedi chairs cradle patrons as nail techs adorn upper and lower piggies in colorful coats of Essie lacquer or CND Shellac's long-wearing gel polish, which stays chip-free for up to three weeks. Paradiso Salon's staff also provides eyebrow-to-ankle waxing services, tanning, makeup application, and eyelash tinting.
Keeping up with the latest industry and fashion trends is a priority for the stylists and aestheticians at Studio 360 Salon. With this knowledge always at-hand, they can help their clients develop flattering new looks, whether they're looking for a basic trim or a dramatic change. Wayward strands can be smoothed out and tamed with thermal conditioning treatments, while stylists also add new depth and dimension to hairdos with highlights or texturizing treatments. Beyond styling hair, the team can also indulge clients with rejuvenating facials, waxing sessions, or body wraps that nourish the skin with nutrients and crumbled multivitamins.
For more than 30 years, the family owners of Salon La Mode have supervised teams of stylists and aestheticians as the staffers cut hair and apply acrylic and gel nails. Natural light helps stylists concoct precise hair colors during the day, and after-hours appointments make Brazilian and eyebrow waxing available to people who spend the daylight hours willing themselves to perform photosynthesis.
