About the hairdryer
Almost a staple requirement for women and some men too who would like to fashion their hair more, the hairdryer is so common that most hotels even have a unit stocked in each room. The basics are that it blows air to dry hair after a hair wash or shower, the temperature and pressure of the air can be controlled. The first ones were not portable and were like having a hat with an air pipe attached to a machine, invented in 1890 by French stylist Alexander Godefroy. The hairdryer allows for hydrogen bonds within each strand to be manipulated when styling and these bonds are powerful but vulnerable to humidity, with only one wash they disappear.
Hairdryer features and accessories
There isn't any specific difference between hairdryers for different hair types and they work with most hair or we'd see salons with multiple 'types'. Instead, the focus is the attachments available with various models, the basic ones being a diffuser, a concentrator and a pick. Diffusers work better for curly hair as they circulate air to the ends of the hair while diffusing the air stream to prevent frizz, this also helps add volume and define curls. Concentrators do the opposite by narrowing the air stream so it blows directly on the hair for smooth and sleek styles. The more broad Concentrators are useful for thick or long hair, on the other hand, narrow concentrators provide curly and frizzy hair with a sleek blowout. The Pick can be used to untangle the hair, stretch it out and create volume at the roots. Essentially it is like using the comb and that is why it is known as the Comb Nozzle as well but not all hairdryers have the pick along with them; this attachment is easily available separately.
Things to consider
You'll want to think about adjustable heat and airspeed setting and also a 'cool shot' button which gives a blast of cool air to close up the cuticle and lock in the style. Another feature is the 'ionic' operation which helps reduce the build-up of static in the hair from friction so once you are done the individual strands are not being repelled by each other, thus making the hair smoother. There is a debate about this feature as some believe it doesn't do much and other stylists swear by it. Using a hairdryer gives room for more disciplined hair and that can be enhanced further during the drying process with hair products so the hair has more hold and lift. Some well-known brands that make these devices are Baby Bliss, Philips, Braun, Panasonic and Remington.
The general guidelines for using them include using it at a minimum distance of 15 cm, hair should not be exposed to too high a temperature for too long and the airstream should be moved about instead of being concentrated on one spot. Also, don't use immediately after a shower, give your hair time to dry a bit so they are less vulnerable. Do not dry out the hair completely, let it retain some moisture.
