It is fair to argue that the contemporary society is obsessed with hair. Nearly each magazine has a hair trend category/section narrating the dos and donts of all hair kinds. It is remarkable that magazines usually list such a variety of hair since hair can be an excellent way to reflect your true personality.
Each strand of hair comprises of the cuticle, cortex, and medulla. The innermost part, the medulla, isn’t always present. It’s an open, and unstructured region. The highly organized and structural cortex, or middle layer of the hair, is the main source of water uptake and the mechanical strength. The cortex contains melanin that colors the fiber depending on the types, distribution and number of melanin granules. The follicle shape determines the shape of the cortex, and the fiber shape is related to how curly or straight the hair is.
People with uncurled hair always have round hair fibers. Oval and any other shaped fibers are usually more curly or wavy. The cuticle is the outer layer. Its compound structure slides as the hair swells. It’s covered with one molecular layer of lipid which makes the hair repel water. The diameter of human hair differs from 0.00067-0.00709 in (017- 0.18 millimeters). There are 2 million small, sweat glands and tubular glands which produce watery fluids which cool the body through evaporation. The glands located at the opening of the hair release a fatty secretion which lubricates our hair.
Hair has a high social significance for humans. It can grow on many external parts of the human body, except on the soles of the feet and the palms of the hands (among other parts). Hair is most recognizable on many people in a small number of areas that are also the ones which are very commonly shaved, plucked, or trimmed. These include the head, ears, face, eyebrows, armpits, and legs, as well as the pubic area. The extremely visible differences between female and male facial and body hair are prominent secondary sex characteristic.
Additionally, hair is a clear extension of your personality; therefore, use it to your great advantage. There’s no excuse not to use the potential of your hair. The hair industry is a huge organization filled with accessories, hairdressers, and products. You’d be surprised to understand that some have to pay an attractive penny for the top-of-the-line hair product. Nonetheless, with all the money and time that is spent on hair, have asked yourself what else our hair is made of? Or if anybody else has similar hair routine as you do?
