Alopecia and Its Types Explained

What Is Alopecia?

Alopecia is a medical term used for hair loss that leaves the skin partially or entirely vacant from hair. One of the most common forms of alopecia mostly affects men, is androgenetic alopecia also known as male pattern baldness. 

Hair loss itself is a natural phenomenon and a part of the hair growth cycle. But when it happens unusually, then it is strongly determined by heredity and genetics. 

Other forms of alopecia may indicate any sort of health problem or can be caused by the side effects of taking any medicine. 

Different Types Of Alopecia – Hair Loss

We have mentioned some of the main forms of alopecia along with their causes. Although alopecia mainly affects the head and scalp, it can occur in any hairy part of the body. 

Cicatricial Alopecia

Any disease or infection such as lupus, psoriasis, lichen, plants, etc. on the skin or scalp can cause alopecia to affect the area permanently. Hair follicles of the skin could be destroyed permanently from any inflammatory reaction of medicine, treatment, or infection. 


It is a fungal skin infection that happens on the scalp. This leaves the affected area itchy with redness. It is considered to be the most common cause of alopecia among children and young adults. However, most of them recover and have chances to regrow hair on the affected area.  

Alopecia Areata

Alopecia areata multilocularis is an autoimmune disease that leaves the multiple areas of skin completely naked from hair. However, there is regrowth, but sometimes the situation relapses for months before recovering. 

Another form of alopecia areata is the universal alopecia where a person experiences the loss of whole-body hair, but it is very rare. 

Telogen Effluvium

This form of alopecia occurs suddenly but temporarily after any kind of emotional or physical shock. For most women, it happens during pregnancy, or after delivery. In some cases, it also happens after significant weight loss, high fever, etc. `

The hair enters the telogen phase, also known as the resting phase, and then falls out gradually. Once the stress passes, the hair follicles feel fresh enough to return to the active phase. Although this process takes about 4 to 6 months, there are expert medicated shampoos for postpartum hair loss from that can help speed up hair growth with visible results after 90 days.

Congenital Alopecia

This form of alopecia is considered very rare. It is particularly the complete absence of hair roots. Some of the mutation genes are responsible for this alopecia form which is caused by hereditary and is called hypotrichosis simplex. This can also begin in childhood in both sexes.  

Medicines, Chemotherapy 

Different situations and diseases in people trigger different types of alopecia and hair loss. For example, those people who may experience nutritional deficiencies, imbalances in their hormonal systems, radiation therapy treatments, or chemotherapy for cancer are most likely to experience hair loss for a longer period of time in their lives.
