What are the most common types of abnormal hair loss? Hair Loss: also known as alopecia or baldness, is a condition that affects millions of people worldwide. The term “hair loss” refers to both male-pattern baldness (androgenic alopecia) and female-pattern baldness (alopecia senilis).

What Are The Different Types Of Hair Loss?

In this section, we’ll take a look at the different types of hair loss and the factors that contribute to each type.

1) Male Pattern Baldness (Androgenic Alopecia):

This is the most common form of hair loss in men. It occurs when your body stops producing enough testosterone, which leads to a male pattern of balding on the crown area and the top of the head.

2) Female Androgenetic Alopecia:

This is also known as female pattern baldness because it affects women more than men. It is caused by an imbalance between estrogen and progesterone levels during menstruation. As a result, the hair follicles become stimulated and stop growing. This results in thinning hair on the crown area and along the sides of the scalp.

3) Telogen Effluvium:

This is a temporary condition where the hairs fall out rapidly due to emotional distress such as shock or grief.

4) Anagen Effluvium:

This is a rare condition where the hairs fall prematurely due to various illnesses like cancer, thyroid problems, etc.

5) Trichotillomania:

This is a psychological disorder where patients pull out their own hair over time.

6) Alopecia Areata:

This is a chronic autoimmune disease where the patient loses his/her hair suddenly without any apparent reason.

7) Chemotherapy-induced Alopecia:

When chemotherapy destroys the hair follicles, it leaves the patient with bald spots.

People suffering from bacterial infections like ringworm, dandruff, and psoriasis may lose their hair.

12) Fungal Infection-related Alopecias:

Patients with fungal infections such as tinea capitis, tinea barbae, and tinea corporis may lose their hair. Tinea capitis usually starts with white patches on the scalp.

13) Lichen Planus:

This is a skin condition characterized by small, flat-topped blisters filled with yellowish fluid.

14) Pityriasis Rubra Pilaris:

This is a skin eruption that causes red bumps on the scalp.

what are the causes of abnormal hair loss?

Hair cycles are like your skin and nails. Your body produces new cells every day and old cells get replaced. When you’re young, your hair grows continuously. As you age, your hair starts to fall out and then regrows again. The process repeats itself throughout your life.

There are many reasons why your hair might start falling out. Some of these reasons include stress, hormonal changes, certain medications, illness, and other health conditions. If you notice that you have lost a lot of hair, contact your doctor right away. He or she will be able to determine if your hair loss is normal or if something else is causing it.

In this study, we found that hair problems were associated with nutrition deficiencies. Iron and zinc deficiencies are commonly seen in children. These deficiencies can lead to poor growth, delayed puberty, and other health issues. A dermatologist or pediatrician should check the scalp and examine the hair for any signs of abnormalities. If there are no signs of disease, then hair loss could be caused by a nutritional deficiency.
