For hair to grow, there needs to be a hair follicle for the hair to develop out of. The germinating layer of the epidermis (skin) starts to grow down into the dermis and this creates the outside layer of the hair follicle. The dermis then grows and rises into the base if the follicle so that the capillaries can enter the papilla and nourish the hair shaft. The bottom of the hair follicle then enlarges to create the hair bulb. The base of the hair bulb then merges out into the outer root sheath which make the inner walls of the hair follicle, the outer sheath then makes the hair root which then surrounds the dermal papilla.. The outer root sheath then grow is inner root sheath, this is the white bit at end of the hair. The hair root, also known as the …show more content…
This is when different types of hair form. For example oval shaft gives curly hair, where as cylindrical shaft gives us straight hair. By the time they reach three quarters of the way up hair follicle they have died and hardened also referred to as keratinised. There is a sebaceous gland inside each follicle. The gland produces a substance called sebum. There is a bulge below the sebaceous gland on the outer root sheath. This is the point o the arrector pili muscle. The bulge produces stem cells that regenerate the follicle during each hair growth cycle. This muscle is what makes your hair stand on end (goosebumps). With in the shaft of hair there is a Medulla which is like a honeycomb keratin structure. The middle layer is the cortex which gives hair the flexibility and stretching strength to the hair. The melanin granules give the hair its color. The cortex is made of layers of keratin that run parallel to each other along the length of the hair shaft. The outer layer of the shaft called the cuticle is made of 6 to 11 layers of almost transparent keratin scales. This layer makes the hair waterproof. Someone with thick hair will have more of these
Hair: composed of columns of dead, keratinized cells bound together by extracellular proteins. Hair has two main sections: The shaft- superficial portion that extends out of the skin and the root- portion that penetrates into the dermis. Surrounding the root of the hair is the hair follicle. At the base of the hair follicle is an onion-shaped structure called the bulb Papilla of the hair and the matrix within the bulb

College is not just about being involved in the classroom. Being involved in multiple clubs in my community back home was an easy way for me to give back to my community. I was constantly involved with volunteer work and I loved the outcome of each project so I wanted to continue to give back. Coming to Charleston, I also wanted to be involved outside of the classroom and give back to my new found home. While visiting Dr. Ross’s office ours, we were showed a video of the women’s “you CAN touch my hair” rally in New York, we knew instantly that we could add our own spin and produce an excellent activism project. In the beginning, our plan was to show the video Good Hair but there was a bit of confusion with the booking of the room. We frantically threw together a project at the end of the day. The purpose was to teach girls that all hair is good hair no matter how straight, curly, kinky, short, long, or big it is.
After many years of progress, the popular culture has begun to appreciate Black people as much as Black people love themselves. The western world is beginning to recover from many years of racial discrimination. Fashion trends usually associated with minority groups have gone from being shunned in popular culture to embraced. Previously, minorities would be forced to conform their image to look more standard, and within recent times, the standard has changed to encompass more people. A prime example of this is the acceptance of natural hair.
I will go further into detail on how to start at any hair stage containing: relaxer, transition, big chop, and ending it with chemical free natural hair. This would explain where most are during their journey. My product will be organized, collected data of possible stages, including details and descriptive pictures for visual examples to back up my topic for support. During the process I will guide you through different varieties of changes that natural hair can be faced with depending on you and where you are in your

Teeny-Weeny Afros (TWAs), mega-sized afros, braids, coils, and heat-straightened looks are among a number of styles being worn by black women, including statement-making fashionistas and image-conscious professionals.
Carville (2012, p 8) defined epidermis as ‘the outer layer of the skin and is comprised of stratified, squamous epithelial cells or keratinocytes’. Epidermis have also various layers that are divided into 4 or 5 layers, stratum germinativum, stratum spinosum, stratum granulosum, stratum lucidum and stratum corneum, respectively. The first layer of epidermis is the stratum corneum, which is also known as a horny layer. The other layer is stratum lucidum, however this is mostly found in a thicker part of epidermis, such as soles of the feet and palms. The middles layer is the stratum granulosum, which is also known as the granular layer. According to Carville (2012, p 9), it is comprised of one to five cells thick of granular cells that contain keratin and shrivelled nuclei’. The next layer after the stratum granulosum is the stratum spinosum, otherwise known as the prickly layer. ‘The stratum spinosum is made up of several layers of polyhedral shaped cells, which have large oval nuclei’ (Carville 2012, p 9). The last layer of epidermis is the stratum germinativum or commonly known as basal layer. This is a layer where basal cells or keratinocytes develop. In comparison to epidermis, dermis have also layers, these are papillary layer, which is composed of loose connective tissue, and reticular layer, which is mostly composed of dense connective
Genetics and hormones determine hair growth patterns. It can also be determined by age and gender. As men age they may have a receding hairline however women would be more likely to have thinning hair. During puberty boys and girls start growing terminal hair in the pubic area and under arms which is determined by hormones. Body hair grows to a short length than head hair. Altered hair growth can be caused by hirsutism. There are different stages of hair growth; anagen, catagen and telogen. Anagen is the first and longest stage of hair growth. It is where the newly formed hair continues to grow. Catagen is the next stage, when the growth of the hair stops. Telogen is the last stage. A new hair is formed in the follicle and the hair that has
3B curls are tighter curls than 3A, but are still fairly “loose”. The circumference of this hair type is similar to the same of an average Sharpie marker. This texture is not as shiny as the 3A hair but is still soft to touch. 3B hair can be dense and/or coarse. This hair type is when your hair starts falling in love with each other and starts knotting up. This hair type is prone to drying. 3B hair is fairly easy to straighten. Model Crystal Westbrook has 3B
Black hair products for natural hair are on the rise, and there is an abundance of amazing new products to benefit our hair. The time to go natural may indeed by now! Just take a look at your television screen. Nearly every woman of color you see is "going natural" and sporting a spiffy hairstyle with dignity and glamor. I have decided to join the ranks of thousands of black women all across America who have cut off their permed hair. Those two-strand twist styles or coils are pretty, but they take so much time. If the styles look too complicated or you don't have the time, here is a simple style for short natural hair you can wear that won't take long at all to perform on a daily basis.
In basic terms, alopecia is a term used in medical circles to refer to baldness. With that in mind, it can be noted that alopecia areata is just one of the many conditions associated with hair loss. In most cases, the condition is occasioned by some round patches of bald spots in the affected individual's head. In some cases, affected individuals can experience total hair loss. In this text, I will discuss the condition and amongst other things highlight its causes, symptoms and treatment.
Also known as Cicatrical Alopecia, Scarring Alopecia is usually caused by complications of other conditions like scleroderma or discoid lupus. Here, the hair follicle (the little opening in your skin where your single hair grows out of) is totally crushed, resulting to the hair not having the capacity to grow back. Unlike Alopecia Areata, the bald patches in the scalp look more “ragged.” This is due to the destruction of the hair follicle that occurs below the skin surface so there may not be much to actually see on the scalp skin surface other than patchy hair loss. Up until today, less is known about the causes of Scarring Alopecia. What is known is that the affected areas may be smooth and clean, or may have redness,
The final layer is called the cuticle. The cuticle’s only function is to protect the Cortex. Since, the constant flow of cell production, the cells push the skin upward. When they are moving up the hair follicle they begin to change and form into certain cell types. The cortex cells change from a round appearance to a flat one. They are squeezed together into layers. The layers are called
