On the other side, the back is longer in the back but shorter and disconnected in the front. Heart face shapes with hair that is medium in texture and in density will best suit this particular hairstyle. A short layered pixie haircut with straight bangs is complementary to a straight hair texture. Style the crown layers and bangs with a small round brush for volume. Apply a root lifting spray before blow-drying for additional height at the root. Part your hair deeply in the front, sweeping feathered angled bangs across the face.

Easy Hairstyle

This is a great way to make the hair and style look fuller and more voluminous. For example, an inverted choppy bob looks great on its own. However, add in a platinum color with exposed dark roots, and all of a sudden, you’ve got an edgy hairstyle like no other.

Flip your part or tuck the hair by your ear to show off your edgy side or part the other way to conseal and create a more polished subtle look. For women in search of a signature look, why not try a sexy cut with a bold new color like this icy white? Still, when you go with such light colors, layers are crucial. Otherwise, it can be hard to see dimension with a solid platinum or silver shade. Gone are the times when long and simple hair was the symbol of femininity and elegance. We live in the modern world where you are encouraged to express your personality with your looks.

Get a Little Rock ‘n Roll With Some Choppy Layers

You can increase the impact of this concave bob hairstyle by adding full arched bangs. The bangs should get gradually longer on the sides until they reach the main weight line. If a dimensional haircut is on your to-do list, there’s nothing better than the blunt bob with a subtle angle. To get the look, your hair should be cut slightly shorter in the back than in the front. You can also use a balayage or ombre coloring technique for more depth. So simple, yet so effective, Kerry Washington's wavy lob gives us hair envy.

Lived-In Strands

To keep bangs from looking piece-y, generously spray the roots with Amika Perk Up Dry Shampoo ($28). While traditional bangs require a lot of upkeep, curtain bangs allow for laid-back styling and stretched out visits to the salon. We love how Jenna Ortega styled them here—slightly tousled to fit the texture of her lob. A stacked bob is comprised of shorter layers in the back, which you can easily style with a volume-boosting product. Make a bold statement by cutting locks into a perfect ultra-short pixie.

A combination of blunt and jagged edges gives a messy style but the classic nature of the bob keeps you looking polished. Wispy and textured edges are great way to make any short cut look more modern and edy. If you don’t like a lot of layers this a great way to create the appearnce of a more layered look without having to sacrifice what you really want. Blunt ends dial up the edge, while tousled layers give it volume. If you want a sleeker, more sophisticated look, just use a fine-bristle brush to lay your tresses down. The soft feathery layers are very elegant and classy — but still modern.

Ask your stylist to incorporate dry texturizing to keep the shape soft and wispy. All short blunt haircuts are easy to style if your hair is straight. Upgrading your shorter hair with soft, layered curtain bangs is a perfect move in 2024. Brunettes who feel comfortable with dramatic looks should definitely consider this haircut idea. Consider face-framing layers on medium-length hair to boost your natural hair texture and give it natural shape.

Wear with bangs across one eye if you want a retro 00’s look. If you have thick hair, this layered pixie is pretty and low maintenance. You don’t really have to do anything to your hair and you’ll still look chic—a little bit of texturizing spray, and you’re good to go.

The Anatomy and Structure of Hair

hair diagram

This is the largest number of hair follicles you will ever have. As long as new hair cells continue to grow in the hair bulb, the hair continues to grow longer. At any point in time, about 90 percent of a person’s total amount of hair is in this growth phase. The first diagram of the hair shows the full structure of the skin.

Structure of hair shaft under a microscope

The first is the anagen phase, during which cells divide rapidly at the root of the hair, pushing the hair shaft up and out. The length of this phase is measured in years, typically from 2 to 7 years. The catagen phase lasts only 2 to 3 weeks, and marks a transition from the hair follicle’s active growth. Finally, during the telogen phase, the hair follicle is at rest and no new growth occurs. At the end of this phase, which lasts about 2 to 4 months, another anagen phase begins. The basal cells in the hair matrix then produce a new hair follicle, which pushes the old hair out as the growth cycle repeats itself.

Structure of hair follicle under a microscope

A club hair may fall out during catagen or telogen, or as it is pushed out by the new hair in the next anagen phase. The cylindrical shaft of the hair under a microscope shows three layers (medulla, cortex, and cuticle) of keratinized cells. Again, the terminal end of the hair follicle shows an expanded hair bulb composed of connective tissue papilla and hair root. Hair under a microscope shows a hair follicle and a cylindrical hair shaft. In a hair shaft, you will find columns of keratinized cells organized into three layers – medulla, cortex, and cuticle.

How can you tell if the hair is under a microscope?

The most important one of these glands is the sebaceous gland, which produces and secretes the natural oils lubricating hairs, namely sebum. So, the hair under a light microscope shows two important features – hair shaft and hair follicle. The important features of the hair shaft are the cuticle, cortex, and medulla, which you might identify with the help of a light microscope.

Here, it shows the different epidermis layers and dermis of animal skin with a hair shaft and follicle. The contraction of the arrector pili muscle pressed upon the sebaceous gland helps them secret within the hair follicle. You will quickly identify and differentiate the animal hair from human hair under a light microscope with the help of their cuticle and medulla features. Generally, the animal hair contains a continuous or stacked medulla in its hair shaft. You will learn more about the microscopic features of the sebaceous glands of the hair follicle in the next section of this article. Sebaceous are the branched acinar holocrine glands that attach to the hair follicle.

You will also find more oval structures in the shaft of cattle or goat hair than in humans. It is very easy to visualize the scales and medulla of a hair shaft. Simply, you should follow a simple procedure and need some instruments. You will find the uniserial, multiserial ladder, vacuolated, and lattice medulla in different animal species.

hair diagram

The cellular or vacuolated medulla are most common in many animal species. All these uniserial, multiserial, cellular or vacuolated, and lattice medulla are shown in the hair labeled diagrams. All these types of medulla of hair are shown on the labeled diagrams. The appearance of the medulla of different types of hair is different.

Hair and Scalp Disorders

But the root of the cat hair is elongated and does not possess any distinct shape. Let’s see some of the common and important features of the hairs from other different parts of an animal’s body. The hair may be straight, curly, and kinly in different animal species.

Structure and Function

It has several types of stem cells, which develop into specialized cells and can renew themselves over a long period of time. The base of the root of a cat’s hair shows a frayed fibrils appearance. In the labeled diagram of the cat’s hair, I tried to show some of the important features from the hair shaft and follicle. You will find numerous blood vessels and numerous connective tissue fibers in the connective tissue of the hair follicle. These numerous vessels and fibers form the basket-like network around the lower end of the hair follicle. The outer layer of the hair follicle starts from the cuboidal cells of the outer layer and continues with the stratum spinosum of the skin.

Telogen effluvium describes a disruption in the normal hair growth and rest cycles that results in excessive shedding and hair loss. This condition can be precipitated by physical stress, such as surgery or malnutrition, or by medical exposure, such as chemotherapy and common medications. The hair shaft is the portion of your hair that projects from your scalp. The root of each hair is located in a follicle, which is embedded in the skin and nourished by the blood vessels in the dermis (see diagram). In a young adult, scalp follicles typically spend 6 to 8 years in anagen, 2 to 3 weeks in catagen, and 1 to 3 months in telogen. Scalp hairs grow at a rate of about 1 mm per 3 days (10–18 cm/yr) in the anagen phase.

You will see a glassy membrane in the diagram that separates the inner root layer from the outer root layer. The hair bulb represents the hair matrix, and hair follicles stem cells. These hair matrices and stem cells are responsible for forming the hair. The stem cells proliferate, move upwards, and gradually become keratinized to produce the hair. The outer root layer of the hair follicle is continuous with the epidermis. You will find a glassy basement membrane that separates this outer root layer from the surrounding connective tissue.

hair diagram

FGF5 is a key inducer of catagen and FGF5-deficient mice have a prolonged anagen phase. In addition to FGF5, TGF-β1, IL-1b, the neurotrophins NT-3, NT-4 and BMP2/4 and TNF-α have been described to induce catagen [36]. Moreover the follicular papilla is an essential source of growth factors [1, 3, 16, 28]. Through the anagen I–V, hair stem cells proliferate, encloses the dermal papilla, grow downwards to the skin and begin to proliferate hair shaft and IRS, respectively. This phase can last up to 6–8 years in hair follicles [1, 11, 18].

During catagen the proximal of the hair shaft is keratinized and forms the club hair, whereas the distal part of the follicle is involuted by apoptosis [16, 38]. In humans, it pulls the follicles into a vertical position and causes “goose bumps,” but serves no useful purpose. The hair follicles in your skin contain living cells to allow your hair to grow. The shaft—the part of the hair we see—is made up of dead cells and consists of three different layers. As a piece of hair grows, it goes through three phases before it sheds and a new one grows. Again, this diagram shows different layers of rounded nucleated cells that form the outer root layer of the hair follicle.

But, these spinous or petal-like scales are not found in the human hair shaft. The hair shaft under a microscope shows three different distinct layers – an inner medulla, a cortex, and an outer cuticle. The structure of a pencil may be a good analogy for the structure of a hair shaft. The cells rupture to secrete an oily secretion into the lumen of the hair follicle. Again, the ruptured cells are continuously replaced by stem cells located at the edges of the glands. Again, let’s see the cross-section of the hair follicles and try to identify the following features from the labeled diagram.

From bleach blonde hair color to the trendiest hair accessories we will try anything to make our crowns stand out. Our hair grows in so many different shades, places, hair textures, and types, that everyone’s mane is naturally unique. But when it comes to hair anatomy, all of our strands are essentially the same. A piece of hair may look simple, but it’s one of the body's most complicated structures. The hair follicle is the part below the skin, and the hair shaft is what you see above your skin.

In hair follicles, 5-alpha reductase is found in the sebaceous glands, dermal papilla, inner root sheath and outer root sheath (2). And androgen receptor sites are found in dermal papilla cells and sebaceous glands (3). Again, the hair matrix stem cells help form the inner and outer root layer of the hair follicle. There is a dermal papilla at the base of the hair bulb and remains in the skin’s dermis. Hair texture (straight, curly) is determined by the shape and structure of the cortex, and to the extent that it is present, the medulla. The shape and structure of these layers are, in turn, determined by the shape of the hair follicle.

You may find the fragmented, segmented, or continuous medulla in the hair. Spinous or petal-like scales of the cuticles are more or less triangular-shaped. These scales frequently protrude from the hair shaft of the animals. On the other hand, human hair contains fragmented, interrupted, or continuous medulla in its shaft. Again, there is some significant difference in the scale patterns of the cuticles of human and animal hairs. I think these identifying features of the hair shaft and follicle might help you identify the hair at your laboratory with the help of a light microscope.

Hair and follicle morphology

Lanugo, vellus and terminal hairs follow the same basic architectural principles. The first “coat” that is formed is fine, long, variably pigmented lanugo hair, which is shed in an anterior to posterior wave during last trimester of gestation. A second coat of fine, shorter, unpigmented lanugo hair then grows in all areas except the scalp and is shed 3–4 months after birth. After these first two cycles, hair starts to grow in an asynchronous “mosaic” pattern rather than in waves [2]. In utero, type and distribution of each hair follicle over the entire body are determined.

Medulla

Hair follicle melanocytes and their precursors reside in the hair matrix and along the outer root sheath of anagen hair follicles. Melanin synthesis is established in lysosome-related organelles named melanosomes. In the precortical matrix, these melanosomes are transferred to the hair shaft keratinocytes and formed a pigmented hair shaft. The hair follicle also contains melanocyte stem cells, which are located in the bulge and in the secondary hair [33–35]. At any given time, about 90% of the scalp follicles are in the anagen stage.

During the first few months of infancy there grow fine, short, unpigmented hairs called down hair, or vellus. Vellus covers every part of the body except the palms of the hands, the soles of the feet, undersurfaces of the fingers and toes, and a few other places. The hairs of the scalp, eyebrows, and eyelashes are of separate types from these others and develop fairly early in life. On the scalp, where hair is usually densest and longest, the average total number of hairs is between 100,000 and 150,000. Human hair grows at a rate of about 0.5 inch (13 mm) per month. The hair follicle sits underneath the skin’s surface and extends down into the dermis layer of your skin.

You will find different secretory cells in the structure of the sebaceous gland of an animal’s skin. So, let’s know the specific identifying features of a hair under a light microscope. Here, I will enlist some important identifying features of hair and hair follicles for transverse and cross-sectioned samples. There is less interest for the mechanism of the hair shedding but from the patient’s perspective it is probably the most important part of the hair growth. It is not unusual for human telogen hairs to be retained from more than one follicular cycle and this suggests that anagen and exogen phases are independent.

Anatomy, Hair

So, the cells of the lower end of the hair root and hair bulbs possess the germinative matrix. So, let’s discuss these three different layers of the hair follicle with their microscopic features. I will show all these microscope figures of different animals’ hair in the labeled diagrams section.

Hair is extremely sensitive to air movement or other disturbances in the environment, much more so than the skin surface. This feature is also useful for the detection of the presence of insects or other potentially damaging substances on the skin surface. This is visible in humans as goose bumps and even more obvious in animals, such as when a frightened cat raises its fur. Of course, this is much more obvious in organisms with a heavier coat than most humans, such as dogs and cats. Hair shaft synthesis and pigmentation only take place in anagen [11]. The degree of axial symmetry within the hair bulb determines the curvature of the final hair structure [35].

Muscles

The perifollicular sheath collapses and vitreous membrane thickens. Eventually, the lower hair follicle becomes reduced to an epithelial strand, bringing the dermal papilla into close proximity of the bulge [36]. The epithelial strand begins to elongate and finally reaches to just below the insertion of pilar muscle. The column eventually reduces to a nipple and forms secondary hair germ below the club. The club hair itself is formed from cortical and cuticle cells only, and it is characterized by a lack of pigmentation [2, 37]. The presence of hairless gene mutation contributes to the failure of dermal papilla migration toward the bulge area in catagen phase [3].

Your hair shaft consists of three layers

Two neural networks innervate hair and hair follicles, and both contain sensory nerve fibers and autonomic nerve fibers. One of the neural networks is made up of sensory C fibers and sympathetic fibers and surrounds the neck of the hair follicle. The other is made up of longitudinal A-delta fibers and circular C fibers and encircle the midsection of the hair follicle, between the isthmus and the sebaceous gland. Nearby nerves also innervate the proximal arrector pili muscles. Analysis of certified premium shea butter can replace sebum to accomplish moisturizing and to fill the gaps between cuticle cells and to keep hair shiny and flexible. Immediate help can be achieved through correct brushing to distribute natural Premium Grade shea butter,(important to note , see similarities between Sebum and Shea chemical makeup).

A hair follicle consists of two main layers, an inner (epithelial) root sheath and an outer (fibrous) root sheath. At the base of the hair follicle is the hair bulb, which houses the dermal papillae and hair matrix cells. It is formed from dermal connective tissue, supplies blood to the epithelial sheath and holds undifferentiated hair stem cells. The cells of the hair follicle actively change during the growth cycle of a hair. The isthmus is the lower portion of the upper part of hair follicle between the opening of the sebaceous gland and the insertion of arrector pili muscle.

The keratin that makes up the major part of the hair is formed by amino acids molecules sourced from the food we eat. This protein is also found in our fingernails, toenails, and skin according to the American Academy of Dermatology (AAD). The shaft is the visible part of the hair that sticks out of the skin. The hair root is in the skin and extends down to the deeper layers of the skin.

Specialized hairs called vibrissae, or whiskers, serve as sensory organs for certain nocturnal animals. The specially modified hairs of the porcupine are called quills and serve defensive purposes. The cross-sectional shape of hair also determines the amount of shine that the hair has. Straighter hair is shinier because sebum from the sebaceous gland can easily travel down the hair. With curly hair, the sebum has trouble traveling down the hair, making it look more dry and dull.

The bulge producesstem cells which regenerate the follicle during the next hair growth cycle. This produces an oily substance calledsebum from a duct which opens up into the hair follicle about halfway downfrom the skin surface. Three different types of hair cell then form(see hair shaft structure diagram below). By the time these cells are a third ofthe way up the follicle, they have died and fully hardened (keratinized). The dermis then grows upwards into the base of thefollicle to form the dermal papilla.

When taking history in a patient with hair loss, it is imperative to determine what the patient is experiencing. Hair loss can refer to increased daily hair loss, which a clinician will elicit by asking if the patient notices more hair on his or her pillow or more hair in the shower after bathing. Teasing out this distinction is necessary to determine the correct diagnosis. Compare secreation of Sebum fram sebaceous gland vs shea butter and their similarities.

Our team is growing all the time, so we’re always on the lookout for smart people who want to help us reshape the world of scientific publishing. Hairs first appear after about three months of embryonic development. These hairs, collectively known as lanugo, are extremely fine and unpigmented. Sixteen amino acids form keratin, with cysteine having the highest concentration.

I hope you already got these specific characteristics of hairs from different animals and can identify them under a light microscope. So, when you find these characteristic features under a light microscope, you may easily tell them hairs. Again, you may identify the hair based on specific identifying features in different animals. The medulla of the rabbit hair shaft is a multiserial ladder and shows a ribbon-like appearance.
