Hair Accessories Comeback as True Fashion Accessory
It seems that hair accessories, which have long been shamefully ignored by luxury fashion accessory designers, have been making a long overdue (in my opinion) comeback. Now if you’re thinking I’m referring to the thick padded satin or velvet headbands that you once used to hide a very ugly hair day or those abominable things called ‘scrunchies’, that you made sure you destroyed all evidence that you ever owned any, then you are very wrong indeed
What is most appealing about the hair accessory ‘comeback’ is that they have made a ‘comeback’ as a true fashion accessory that can take a worthy place next to any designer bag, shoes or jewellery for that matter. Over the last few fashion seasons we have seen the emergence of hair adornments and hair pieces on runways, not as an added afterthought, but as a respectable part of the outfits and entirety of the show. Headbands and headpieces are now being created with true designer flair and workmanship, in styles and using materials that would previously have been hard to imagine.
Take headbands for instance:
Designs
Headbands are now being designed in all sizes ranging from super slim to extra wide, in all designs ranging from the traditional hard headband to the soft headband, the headband scarf, the head wrap etc.
Sizes
In addition to the change in styles and designs we have seen a change in the way hair accessories such as headbands are worn. Headbands are now worn as part of the hairstyle, where the headband slips into the hairstyle and features as a part of the hairstyle you are wearing rather than as a way of pulling hair back off the face or concealing a bad hairstyle. Headbands or head wraps are also being worn on top of the hair in a ‘hippy’ style. This look can range from a true ‘hippy’ look using leather straps and ties to a highly glamorous bijoux hippy look using decorative crystal adorned or metallic wraps.
Hair Styles
What’s also incredibly inspiring about hair accessories such as headbands/head wraps etc is that now, unlike previously, women are incorporating hair accessories such as headbands in their hair styles no matter what length or style their hair is – headbands can be worn on all hair lengths ranging from short hair to long hair and added to up-dos as well. Even women sporting serious rock chic short hairstyles look great with a contrasting stylish headband.

Liquid Crystals and Electronic Calculators
Matter is anything that has mass and takes up space. The term refers to all real objects in the natural world, such as marbles, rocks, ice crystals, oxygen gas, water, hair, and cabbage. The term ‘states of matter’ refers to the four physical forms in which matter can occur: solid, liquid, gaseous, and plasma. Our understanding of the nature of matter is based on certain assumptions about the particles of which matter is composed and the properties of those particles. This understanding is summarized in the kinetic theory of matter according to which, all matter is composed of tiny particles. These particles can be atoms, molecules, ions, or some combination of these basic particles. Therefore, if it were possible to look at the tiniest units of which a piece of aluminum metal is composed, one would be able to observe aluminum atoms. Similarly, the smallest unit of a sugar crystal is thought to be a molecule of sugar.
The fundamental particles of which matter is composed are always in motion. Those particles may rotate on their own axes, vibrate back and forth around a certain definite point, travel through space like bullets, or display all three kinds of motion. The various states of matter differ from each other on the basis of their motion. In general, the particles of which solids are made move very slowly, liquid particles move more rapidly, and gaseous particles move much more rapidly than either solid or liquid particles. The particles of which plasma are made have special properties.
Solid, liquid, and gas: these are the three most common forms of matter. But some materials do not fit neatly into one of these three categories. Liquid crystals are one such form of matter. Liquid crystals are materials that have properties of both solids and liquids. They exist at a relatively narrow range of temperatures. At temperatures below this range, liquid crystals act like solids. At temperatures above the range, they act like liquids. The behavior of liquid crystals is due to the shape of the molecules of which they are made. We can think of those molecules as looking like cigars or pencils: they tend to be long and thin. They can be arranged within a material in one of three forms. In nematic crystals, the molecules are all parallel to each other but are free to move back and forth with relation to each other. The molecules in smectic crystals are also parallel to each other but they do not move back and forth; they are, however, further arranged in layers that do pass over each other. And the molecules in cholesteric crystals occur in highly structured layers that are set at slightly different angles than the ones above and below them.
The interesting property about liquid crystals is the way they transmit light. Light can pass through a liquid crystal more easily in one direction than in another. If we look at one of the crystals from one direction, we might see all the light passing through it. But from another direction, no light would be visible. The crystal would be dark. The arrangement of molecules in a liquid crystal can be changed by adding energy to the crystal. If we warm the crystal, for example, molecules may change their position with relation to each other. This fact is utilized in new kinds of medical thermometers that change color with temperature. As body heat changes, the molecules in the liquid crystal change, the light they transmit changes, and different colors appear.
Liquid crystals are also used for the display in electronic calculators. When we press a button on the calculator, we send an electric current through the display. The electric current causes molecules in the liquid crystal to change their positions. More or less light passes through the crystal, and numbers either light up or go dark. The motion of the particles of matter is a function of the energy they contain. Suppose that we add heat, a form of energy, to a solid. That heat is used to increase the speed with which the solid particles are moving. If enough heat is added, the particles eventually move rapidly enough that the substance turns into a liquid: it melts.
One can distinguish among solids, liquids, and gases on two levels: the macroscopic and submicroscopic. The term macroscopic refers to properties that can be observed by the five human senses, aided or unaided. The term submicroscopic refers to properties that are too small to be seen even with the very best of microscopes. On the macroscopic level, solids, liquids, and gases can be distinguished from each other on the basis of shape and volume. That is, solids have both constant shape and constant volume. Liquids have constant volume but indefinite shape. Gases have neither constant volume nor constant shape. They take the size and shape of whatever container they are placed into.
These macroscopic differences among solids, liquids, and gases reflect properties of the particles of which they are made. In solids, those particles are moving very slowly and tend to exert strong forces of attraction on each other. Since they have little tendency to pull away from each other, they remain in the same shape and volume. The particles of a liquid are moving more rapidly, but they still exert a significant force on each other. These particles have the ability to flow past each other but not to escape from the attraction they feel for each other. The particles of a gas are moving very rapidly and feel very little attraction for each other. They fly off in every direction, preventing the gas from taking on either definite shape or volume.
Plasma is considered to be the fourth state of matter. Plasmas have been well studied in only the last few decades. They rarely exist on Earth, although they occur commonly in stars and other parts of the universe. A plasma is a gaslike mixture with a very high temperature. The temperature of the plasma is so high that the atoms of which it is made are completely ionized. That means that the electrons that normally occur in an atom have been stripped away by the high temperature and exist independently of the atoms from which they came. Plasma is, therefore, a very hot mixture of electrons and positive ions, the atoms that are left after their electrons have been removed.
