Hair is composed of a protein called keratin<\/a>. Hair isn\u2019t the only part of your body that\u2019s made of keratin; this protein is also responsible for skin and nails, too.<\/p> The word \u2018keratin\u2019 might sound familiar because you\u2019ve possibly heard your hairstylist mention it before. There are plenty of misconceptions about keratin floating around out there, however, so let\u2019s take a few minutes to debunk those.\u00a0<\/p> First, keratin is a naturally occurring protein. It can be found in epithelial cells on the surface of your skin. But keratin is not one-size-fits-all. There are different kinds of keratin, and they\u2019re responsible for different types of growth and structure. In fact, humans aren\u2019t the only ones with keratin\u2014keratin is also found in some animals.<\/p> There are actually 54 types of keratin that your body can make. Half of those types of keratin reside inside of the hair follicles found all over your body.\u00a0<\/p> Keratin is an intermediate filament-forming protein. Interestingly, the structure and function of a keratin protein are dependent upon its amino acid chains. Because keratin can\u2019t be dissolved in water, solvent, acids, or even alkalines, its structure will remain mostly intact when it gets exposed to most of the body\u2019s chemicals.\u00a0<\/p> Keratin proteins do rely largely on water, however, to maintain and support their functionality and size. For example, a protein can lose its length when some molecular bonds break apart at a high temperature<\/a> (which is why you should avoid using scorching high temperatures on your hair!). <\/p>\n\n\n\n The journey your hair goes on begins at the hair root<\/a>, which is located underneath your skin. At the hair root, cells band together and create keratin. The root itself can be found inside of a hair follicle.\u00a0<\/p> Once your hair begins to grow, it pushes up from the root and makes its way out of the follicle, which is when you\u2019ll actually start seeing it. Although we usually talk about the hair that\u2019s on your head, the best way to visualize this is when your hair starts to grow back after shaving. The stubble begins to pop out of your hair follicles after a day or two of growth. There are also small blood vessels located at the base of each follicle to feed the hair root and ensure it continues growing.\u00a0<\/p> But there\u2019s more to it! For one, when you actually are able to see the hair at the skin\u2019s surface, the cells that make up that strand of hair are no longer alive. That means that all of the hair on your body that you can see is composed of dead cells, which is why you can get a new \u2018do without worrying about every snip of the scissors hurting your hair.\u00a0\u00a0<\/p> Those hair follicles aren\u2019t on their own, either. Almost every hair follicle is connected to a sebaceous gland, which produces the oil that allows your hair to have that shiny appearance<\/a> and keeps it healthy and moisturized.<\/p>\n\n\n\n Okay, so do the different types of keratin have anything to do with whether your hair will be straight, wavy, or curly? All hair has two significant components<\/a>: the hair shaft and the hair follicle.\u00a0<\/p> The shafts of your hair are the strands that you see flowing from your head. The follicle of your hair is within the skin of your scalp. Both of these contribute to the structure of your hair and its shape.\u00a0<\/p> First, let\u2019s discuss the hair follicle. The curvature of the follicle is a large part of what determines the shape of our hair. For example, if you looked at the cross section of someone with straight hair, you\u2019d see a perfectly round follicle. A cross section of curly hair, alternately, would be oval. It\u2019s also important to note that when you have curly or wavy hair, the hair\u2019s undergo an asymmetrical keratinization process, which is what gives you all those twists and curls in your hair.\u00a0<\/p> You might be wondering what role the hair shaft plays in the texture. The answer is protein bonding. The hair that you see is composed of dead cells that are full of keratin. The protein has copies of an amino acid called cysteine, which has a special chemical group that contains sulfur.\u00a0<\/p> This allows it to create strong bonds with other molecules that also contain sulfur. Since the hair largely is keratin, the cysteine amino acids can actually go ahead and bond with other cysteines further down on the hair\u2019s shaft\u2014which creates a curl. Ultimately, the hair follicle is far more influential in determining if you\u2019ll have curly or straight hair than the hair shaft is, however. <\/p>\n\n\n\n It\u2019s clear to us that hair is truly amazing.
