10 Types Of Hair Loss

1. Androgenetic alopecia (male or female pattern hair loss)

Androgenetic alopecia, also known as age-related hair loss, is the most common type of hair loss. It is caused by a combination of factors, including genetics, hormones, and the natural aging process. It typically begins in the late twenties or early thirties, and progresses gradually over time.

Androgenetic alopecia is caused by the interaction of hormones and genetics. The hormone testosterone, which is present in both men and women, can be converted into a hormone called dihydrotestosterone (DHT) by an enzyme called 5-alpha reductase. DHT can bind to receptors on the hair follicles and shrink them, leading to hair loss.

Genetics also play a role in androgenetic alopecia. The condition tends to run in families, and people who have a family history of hair loss are more likely to develop it themselves.

In men, androgenetic alopecia usually presents as a receding hairline and thinning of the hair on the crown of the head. This is often referred to as male pattern baldness. In women, it usually presents as a diffuse thinning of the hair, with no obvious pattern.

Androgenetic alopecia is not a life-threatening condition, but it can affect a person’s self-esteem and quality of life. There are treatments available that can help to slow down or stop the hair loss, and to stimulate new hair growth. These treatments may include medications, such as minoxidil or finasteride, or surgical procedures, such as hair transplants. It is always important to consult with a healthcare provider for advice on the best course of treatment for androgenetic alopecia.

2. Alopecia areata

Alopecia areata is an autoimmune disorder that causes hair loss. In this condition, the body’s immune system mistakenly attacks the hair follicles, leading to hair loss. It can affect people of all ages, and it can cause hair to fall out in patches, or it can cause total hair loss (alopecia totalis) or loss of all body hair (alopecia universalis).

The exact cause of alopecia areata is not fully understood, but it is thought to involve a combination of genetic and environmental factors. People who have a family history of autoimmune disorders, such as type 1 diabetes or lupus, are more likely to develop alopecia areata.

The symptoms of alopecia areata vary depending on the severity of the condition. In mild cases, it may cause only a few small patches of hair loss. In more severe cases, it can cause widespread hair loss, or total loss of all body hair.

Alopecia areata is not a life-threatening condition, but it can affect a person’s self-esteem and quality of life. There are treatments available that can help to slow down or stop the hair loss, and to stimulate new hair growth. These treatments may include medications, such as corticosteroids or immunosuppressants, or light therapy. It is always important to consult with a healthcare provider for advice on the best course of treatment for alopecia areata.

3. Telogen effluvium

Telogen effluvium is a type of hair loss that occurs after a physical or emotional trauma, such as surgery, childbirth, or a stressful event. It is caused by an interruption in the hair growth cycle, and it can lead to shedding of the hair.

The hair growth cycle is the process by which new hair is produced, and it involves several stages, including the growth phase (called the anagen phase), the resting phase (called the telogen phase), and the shedding phase (called the exogen phase). In telogen effluvium, hair that is in the resting phase is shed prematurely, resulting in thinning hair or bald patches.

The exact cause of telogen effluvium is not fully understood, but it is thought to be triggered by physical or emotional stress. Physical stressors, such as surgery or childbirth, can cause a sudden increase in the shedding of hair. Emotional stressors, such as a major life change or a traumatic event, can also cause hair loss by disrupting the hair growth cycle.

The symptoms of telogen effluvium typically appear several weeks after the triggering event. In most cases, the hair loss is diffuse, and it affects the entire scalp. It may also affect other areas of the body, such as the eyebrows or the pubic area.

Telogen effluvium is usually a temporary condition, and the hair will regrow on its own once the underlying cause is resolved. However, in some cases, the hair loss may be more severe or long-lasting, and treatment may be necessary. Treatment for telogen effluvium may involve addressing the underlying cause of the stress, or using medications to stimulate hair growth. It is always important to consult with a healthcare provider for advice on the best course of treatment for telogen effluvium.

4. Traction alopecia

Traction alopecia is a type of hair loss that is caused by repeated pulling or tension on the hair. It is most commonly seen in people who wear tight hairstyles, such as cornrows or braids, or who use hair extensions or other hair-styling devices that apply tension to the hair.

The hair follicles are the structures in the skin that produce hair, and they are sensitive to damage from repeated pulling or tension. When the hair follicles are damaged, they may be unable to produce new hair, leading to hair loss. In severe cases of traction alopecia, the hair follicles may be permanently damaged, resulting in permanent hair loss.

Traction alopecia usually affects the hair at the front and sides of the scalp, near the hairline. It may also affect the eyebrows, the beard, or other areas of the body where the hair is subject to repeated pulling or tension. In most cases, the hair loss is gradual, and it may not be noticeable until a significant amount of hair has been lost.

Treatment for traction alopecia may involve avoiding tight hairstyles or hair-styling devices that apply tension to the hair. In some cases, medications or other treatments may be necessary to stimulate hair growth and prevent further hair loss. It is always important to consult with a healthcare provider for advice on the best course of treatment for traction alopecia.

5. Scarring alopecia

Scarring alopecia is a type of hair loss that is caused by scarring of the scalp. It is a rare condition, and it can be caused by a variety of factors, including autoimmune disorders, physical trauma, or radiation treatment. It can lead to permanent hair loss.

Autoimmune disorders, such as lichen planopilaris or discoid lupus, can cause scarring alopecia. In these conditions, the body’s immune system attacks the hair follicles, leading to scarring and permanent hair loss.

Physical trauma, such as burns or radiation treatment, can also cause scarring alopecia. These types of injuries can damage the hair follicles, leading to scarring and permanent hair loss.

The symptoms of scarring alopecia vary depending on the underlying cause. In most cases, it causes patchy hair loss, with well-defined bald patches on the scalp. The hair loss is usually permanent, and it cannot be reversed.

Treatment for scarring alopecia may involve addressing the underlying cause of the condition, if it is known. In some cases, medications or other treatments may be necessary to stimulate hair growth and prevent further hair loss. It is always important to consult with a healthcare provider for advice on the best course of treatment for scarring alopecia.

6. Anagen effluvium

Anagen effluvium is a type of hair loss that is caused by damage to the hair follicles. It is a severe and rapid form of hair loss, and it can be caused by a variety of factors, including chemotherapy, radiation treatment, or certain medications.

The hair follicles are the structures in the skin that produce hair, and they are sensitive to damage from certain substances. Chemotherapy and radiation treatment, for example, can damage the hair follicles, leading to hair loss. Certain medications, such as those used to treat gout or high blood pressure, can also cause hair loss by damaging the hair follicles.

In anagen effluvium, the hair loss occurs rapidly, and it affects the entire scalp. The hair may fall out in clumps, or it may thin gradually over time. In severe cases, the hair loss can be complete, resulting in baldness.

Anagen effluvium is usually a temporary condition, and the hair will regrow on its own once the underlying cause is resolved. However, in some cases, the hair loss may be more severe or long-lasting, and treatment may be necessary. Treatment for anagen effluvium may involve addressing the underlying cause of the hair loss, or using medications to stimulate hair growth. It is always important to consult with a healthcare provider for advice on the best course of treatment for anagen effluvium.

7. Involutional alopecia

Involutional alopecia is a type of hair loss that occurs as part of the natural aging process. It is a common condition, and it is caused by a change in the hair growth cycle, resulting in a gradual thinning of the hair.

The hair growth cycle is the process by which new hair is produced, and it involves several stages, including the growth phase (called the anagen phase), the resting phase (called the telogen phase), and the shedding phase (called the exogen phase). As people age, the hair growth cycle changes. The growth phase becomes shorter, and the resting phase becomes longer, so that hair stays in the scalp for a shorter time before it is shed.

Involutional alopecia typically begins in the late twenties or early thirties, and it progresses gradually over time. In most cases, it causes a diffuse thinning of the hair, with no obvious pattern. It may also cause the hairline to recede slightly.

Involutional alopecia is not a life-threatening condition, but it can affect a person’s self-esteem and quality of life. There are treatments available that can help to slow down or stop the hair loss, and to stimulate new hair growth. These treatments may include medications, such as minoxidil or finasteride, or surgical procedures, such as hair transplants. It is always important to consult with a healthcare provider for advice on the best course of treatment for involutional alopecia.

8. Telogen hair loss

Telogen hair loss is a form of hair loss that affects both men and women. It is the result of the hair growth cycle being disrupted, leading to the loss of hair from the scalp.

During the hair growth cycle, hair goes through three main stages: anagen, catagen, and telogen. The anagen phase is the growth phase, during which the hair follicle produces new cells and the hair shaft grows longer. The catagen phase is a transitional phase, during which the hair follicle shrinks and the hair shaft becomes detached from the follicle. The telogen phase is the resting phase, during which the hair follicle is inactive and the hair shaft is released from the follicle.

In a healthy individual, the majority of hair follicles are in the anagen phase, while only a small percentage are in the telogen phase. However, in individuals with telogen hair loss, the proportion of hair follicles in the telogen phase increases, leading to the loss of hair from the scalp.

There are several factors that can cause telogen hair loss, including hormonal changes, certain medications, and physical or emotional stress. Hormonal changes, such as those that occur during pregnancy or menopause, can disrupt the hair growth cycle and cause more hair follicles to enter the telogen phase. Certain medications, such as those used to treat depression or high blood pressure, can also cause telogen hair loss. Physical or emotional stress can also trigger the hair growth cycle to be disrupted, leading to hair loss.

Telogen hair loss is usually temporary and the hair will regrow on its own once the underlying cause is resolved. In some cases, however, treatment may be necessary. This can include changing medications, addressing underlying hormonal imbalances, or managing stress. A doctor or dermatologist can help determine the best course of treatment for an individual with telogen hair loss.

9. Diffuse hair loss

Diffuse hair loss is a type of hair loss that affects the entire scalp, rather than specific areas. It is characterized by thinning of the hair all over the scalp, rather than the development of bald patches. Diffuse hair loss can affect both men and women, and can have a variety of causes.

One common cause of diffuse hair loss is androgenetic alopecia, also known as male or female pattern baldness. This condition is caused by a combination of genetic factors and hormones, and is characterized by a gradual thinning of the hair on the scalp. In men, this typically results in a receding hairline and thinning of the hair on the crown of the head, while in women it typically results in thinning of the hair on the top of the head.

Another cause of diffuse hair loss is telogen effluvium. This condition is characterized by a sudden, widespread shedding of hair, often as a result of a physical or emotional shock to the body. This can include things like severe illness, surgery, or extreme stress. In most cases, the hair will regrow on its own once the underlying cause has been addressed.

Diffuse hair loss can also be caused by certain medical conditions, such as thyroid disorders or iron deficiency anemia. In these cases, treating the underlying condition can help restore normal hair growth.

Treatment for diffuse hair loss depends on the underlying cause. In some cases, no treatment may be necessary and the hair will regrow on its own. In other cases, treatment may be necessary to restore normal hair growth. This can include medications to address hormonal imbalances or underlying medical conditions, or lifestyle changes to manage stress. A doctor or dermatologist can help determine the best course of treatment for an individual with diffuse hair loss.

10. Central centrifugal cicatricial alopecia

Central centrifugal cicatricial alopecia (CCCA) is a type of hair loss that primarily affects women of African descent. It is characterized by hair loss that begins at the crown of the head and gradually spreads outward. The hair loss is typically accompanied by scarring of the scalp, which can make it difficult for new hair to grow.

CCCA is thought to be caused by chronic inflammation of the hair follicles. This inflammation can be triggered by a variety of factors, including heat styling, tight braiding, or the use of certain hair products. The chronic inflammation leads to scarring of the scalp, which in turn prevents new hair from growing.

The exact cause of the chronic inflammation that leads to CCCA is not well understood. However, researchers believe that it may be related to an overactive immune system. In some cases, CCCA may be associated with other autoimmune disorders, such as lupus or scleroderma.

The symptoms of CCCA include hair loss that begins at the crown of the head and gradually spreads outward, as well as scarring of the scalp. In some cases, the scalp may appear reddened or inflamed. The hair loss can be permanent if left untreated.

Treatment for CCCA typically involves medications to reduce inflammation and promote hair growth. This can include corticosteroids, which are used to reduce inflammation, and minoxidil, which is used to promote hair growth. In severe cases, surgery may be necessary to remove scar tissue and promote new hair growth. A doctor or dermatologist can help determine the best course of treatment for an individual with CCCA.
