People who suffer from hair loss often wonder what type of hair loss they belong to. In most cases, it is one of the four below. It's safe to say it's over 90%.


This is because you need to know the type of hair loss you are in, so that you can find a solution that suits you. Read the details below and compare it to yours.


Female pattern alopecia

The forehead line in front of alopecia, where the middle part of the head falls off mainly and the degree of hair loss is less than that of men,

is preserved. It belongs to androgenetic alopecia, has a strong genetic tendency, and is related to male hormones. It often begins to appear from the age of 25 to 30, and as the hair becomes thinner and shorter, the parting area becomes thinner. It can occur during pregnancy or about 2 to 5 months after childbirth, and although recovery is possible in most cases, there are cases of permanent hair loss.
 
Genetically, a lot of male hormones are secreted or taking drugs that have male hormone action can be the cause. In addition to hair loss, it can also be caused by systemic hirsutism, virilization, and other endocrine abnormalities.

The symptoms are progressively hair loss with age. Unlike men, there is no specific pattern and overall hair loss occurs on the head. As the hair gradually becomes thinner and the boundary between the face and the scalp is maintained, the thick hair in the center of the scalp gradually falls out, but only the center of the head gradually falls off. However, it is rare for the forehead to fall off or become completely bald.
   

Male pattern alopecia

Also known as androgenetic alopecia, alopecia that occurs mainly in men in their 20s and 30s.

It is divided into scarring and non-scarring. Scarring is a condition in which hair follicles are destroyed and restored to fibrous tissue, resulting in permanent hair loss, which is caused by trauma, burns, tumors, and infection. Non-scarring is when the tissue is not fibrous and the hair follicles are preserved as it is. 

The cause is mainly due to genetic factors, the influence of male hormones and aging. Because there is a dominant inheritance, if one of your parents is bald in the ancestry, you are more likely to become bald. In women, androgenetic alopecia can occur because the ovaries secrete male hormones.

In the case of women, the onset and progression is slower than in men, and hair loss on both sides of the forehead, which is common in men, is very rare, and the outline of the hair on the forehead is maintained. The hair becomes thinner as a whole, and this symptom appears most clearly near the crown.

 

Alopecia areata

A disease in which the hair loss area on the head becomes round like a circle.

It usually appears in one place with a diameter of 1 to 2 cm, but sometimes it is clustered in several places and fuses in an irregular shape, and both feet may fall out. There is usually no abnormality in the skin of the bald area, but it is slightly lowered or reddish than the surrounding area, and when observed under a microscope, the skin tissue is inflamed. Usually there is hair loss, but beard, eyebrows, eyelashes, pubic hair, etc. may fall out, and in rare cases, all hair on the body may fall out.

There are various processes, but it usually returns to normal in 2-3 months. Sometimes there is a period of white hair before normal hair growth.

As for the cause, there are several theories such as allergy theory, genetic theory, autonomic nervous system abnormality theory, hair growth cycle disorder theory, endocrine disorder theory, etc., but the definitive one has not been revealed yet.

 

Seborrheic Dermatitis

Seborrheic dermatitis is a chronic inflammatory skin disease that occurs on the scalp and face where the sebaceous glands are concentrated, especially around the eyebrows, nose, lips, ears, armpits, chest, and groin.

The causes of seborrheic dermatitis include genetic factors, family history, food, fungal activity, bacterial infection, hormone influence, mental tension, etc., but the exact cause is still unknown. Erythema, scale, scab, etc. are usually accompanied by itching. If you keep scratching your head because it is itchy, you need to be careful as blood comes out and a secondary bacterial infection occurs. When the disease worsens, the same symptoms occur on the face, ears, armpits, stomach, chest, and back, and there is a very high possibility of recurrence if left untreated.

Since this disease has a kind of constitutional aspect, there is no cure in any way, it is to help by improving the symptoms, and it is important to maintain the improved state through steady management.
