The 5 common hair diseases are:
1. Alopecia Areata: This is a condition where the immune system attacks the hair follicles, causing them to become inflamed and eventually leading to hair loss. There are two types of alopecia areata – patchy (where only small patches of hair are lost) and totalis (where all scalp hair is lost).
2. Androgenic Alopecia: This is the most common type of Hair Loss, affecting both men and women. It is caused by a combination of genetic factors and hormones (androgens). The most common symptom is a receding hairline in men (male pattern baldness), and thinning hair on the crown in women.
3. Trichotillomania: This is an impulse control disorder where people feel an irresistible urge to pull out their own hair, from anywhere on their body. The resultinghair loss can be patchy or widespread, and can lead to significant distress and social isolation.
4. Telogen Effluvium: This is a condition that can be caused by physical or psychological stress, which causes the “resting” phase of the hair growth cycle to lengthen.
As a result, more hairs enter the shedding phase simultaneously, leading to increased overall shedding and temporary thinning of the Hair . In most cases, telogen effluvium is reversible once the underlying cause has been addressed .
5. Scalp Psoriasis: This is a chronic autoimmune condition that causes raised, red scaly patches on the skin .
In some cases , these patches can extend onto areas such as the forehead , ears , or neck . Although scalp psoriasis does not directly cause Hair Loss , it can lead to itching , burning , and soreness which may make it difficult to resist scratching . Scratching can then worsen psoriasis symptoms as well as damage the Hair Follicle s , leading to temporary or permanent Hair Loss .
There are a variety of hair diseases that can affect both men and women. While some hair diseases are genetic, others can be caused by lifestyle choices or underlying medical conditions. Here are 5 common hair diseases:
1. Androgenetic alopecia: Also known as male-pattern baldness, this is the most common type of hair loss in men. It is characterized by a receding hairline and thinning of the hair on the top and crown of the head.
2. Alopecia Areata: This is an autoimmune disease that causes patchy hair loss on the scalp and body.
It can affect people of any age, gender, or race.
3 . Telogen Effluvium: This is a temporary form of Hair shedding that occurs when there is an interruption in the normal growth cycle of the hair follicle.
It can be caused by stress, hormonal changes, certain medications, or severe illness.
4 . Trichotillomania: This is a condition characterized by the urge to pull out one’s ownhair from the roots.
It can lead to bald patches on the scalp or other areas of the body where hair is pulled out repeatedly.
5 . Scalp Psoriasis: This is a chronic inflammatory skin condition that often affects the scalp causing scaly, itchy patches of skin with silvery-white scales.

What are the Common Hair Diseases?
Hair diseases are relatively uncommon, but they can occur. The most common hair disease is alopecia, which is characterized by hair loss. Alopecia can be caused by a variety of factors, including genetics, autoimmune disorders, and certain medications.
Other hair diseases include trichotillomania (a condition that causes people to pull out their own hair), and scalp infections like ringworm.
What is the Most Common Hair Disorder?
The most common hair disorder is androgenetic alopecia, also known as pattern hair loss. It is a condition that affects both men and women and is caused by a combination of genetic and hormonal factors. Pattern hair loss typically begins with a thinning of the hair on the temples and crown of the head in men, and on the top of the head in women.
Over time, the hair loss can progress to complete baldness.
What are the 3 Main Hair Conditions?
The three main types of hair conditions are dry hair, oily hair, and combination hair. Dry hair is characterized by a lack of natural oils and moisture. This can make the hair shafts weak and prone to breakage.
Oily hair is characterized by an overproduction of sebum, which can make the scalp and strands greasy. Combination hair is a mix of both dry and oily areas.
What Disease Takes Away Your Hair?
There are a few different diseases that can cause hair loss, but the most common one is alopecia areata. This is an autoimmune disease that attacks the hair follicles, causing them to fall out. It can affect anyone of any age, but is more common in women and girls.
There is no cure for alopecia areata, but there are treatments that can help the hair to regrow.

Hair Diseases List
There are a variety of hair diseases that can affect both men and women. Here is a list of some of the most common hair diseases:
-Alopecia areata: This is a condition that causes patchy hair loss.
It is thought to be an autoimmune disorder, where the body’s immune system attacks the hair follicles.
-Androgenetic alopecia: This is the most common type of hair loss, affecting both men and women. It is also known as male or female pattern baldness.
Androgenetic alopecia is caused by a combination of genetics and hormones.
-Cicatricial alopecia: This type of hair loss is caused by damage to the skin around the follicle, which leads to scarring and eventual destruction of the follicle. Cicatricial alopecia can be caused by various conditions, including lupus erythematosus, lichen planus, and discoid lupus erythematosus.
-Telogen effluvium: This is a temporary form of hair loss that can be caused by physical or emotional stress, pregnancy, certain medications, or an underlying health condition such as thyroid disease or iron deficiency anaemia.
Rare Hair Disorders
It’s estimated that one in every 200 people have some form of rare hair disorder. That may not seem like a lot, but when you consider that there are 7.53 billion people on the planet, that means there are approximately 37.7 million people with rare hair disorders!
There are many different types of rare hair disorders, ranging from conditions that cause complete hair loss to those that result in abnormal growth patterns.
Some of the more well-known rare hair disorders include alopecia areata (patchy hair loss), trichotillomania (compulsive pulling of hairs), and ectodermal dysplasia (a condition that affects the development of various tissues, including hair).
While there is no cure for most rare hair disorders, there are treatments available that can help manage symptoms and improve quality of life. If you or someone you know has a rare hair disorder, don’t hesitate to reach out to a healthcare professional for more information and support.
What Causes Scalp And Hair Diseases And Disorders
The scalp and hair are susceptible to a variety of diseases and disorders. Some of these conditions are caused by underlying medical problems, while others may be the result of poor hygiene or other environmental factors.
Conditions that can affect the scalp and hair include dandruff, seborrheic dermatitis, psoriasis, eczema, folliculitis, and ringworm.
Dandruff is a common condition that causes flaking and itching of the scalp. Seborrheic dermatitis is another common scalp disorder that produces red, scaly patches on the skin. Psoriasis is a chronic condition that causes thick, red plaques to form on the skin.
Eczema is a general term used to describe various inflammatory conditions that can cause dry, itchy skin. Folliculitis is an infection of the hair follicles that can lead to inflammation and scarring. Ringworm is a fungal infection that affects both the scalp and nails.
Most scalp and hair disorders can be treated with over-the-counter medications or home remedies. However, some conditions may require prescription medications or surgery.
Conclusion
There are a number of common hair diseases that can affect both men and women. Here are five of the most common:
1. Alopecia Areata: This is an autoimmune condition that causes patchy hair loss on the scalp.
It is thought to be caused by a combination of genetic and environmental factors. There is no cure for alopecia areata, but treatments such as corticosteroids, minoxidil, and immunotherapy may help to slow or stop the progression of hair loss.
2. Androgenetic Alopecia: This is the most common type of hair loss, affecting both men and women.
It is caused by a combination of genetic and hormonal factors, and typically results in thinning hair on the top and front of the head. Treatments for androgenetic alopecia include minoxidil, finasteride, low-level laser therapy, and PRP therapy.
3. Telogen Effluvium: This is a temporary form of hair loss that occurs when the hairs enter into a resting phase (telogen) prematurely.
It can be caused by several different things including stress, medication side effects, drastic weight loss, or childbirth. The good news is that telogen effluvium usually resolves on its own within 6-9 months without treatment.
