Suffering from Alopecia? Know about its Types and Causes

Advertisement

Alopecia or hair loss is more commonly known as “baldness.” It may be confined to hair loss with or without scarring, reversible or permanent, and can be limited to scalp or universal. Alopecia can be inflammatory in nature and scaling may be sited in the affected area. A person may feel a tingling sensation where there has been hair loss. Uneven hair loss may also happen in a short span of time, and is usually noticeable on one side. Bald patches may affect even the healthy hair around them, causing hair to lose their grip from the follicles, allowing them to be pulled out effortlessly. So, now that you are sure you are suffering from alopecia, it is important to know which type you have.

1 Types of alopecia and their causes

Androgenic alopecia (male and female pattern)

Male pattern baldness is the most common type and usually starts at an early stage. It generally follows a pattern and attacks the front hairline first, moving to the vertex. This pattern is genetically determined and usually creates a horseshoes-shaped hairline. It is the same in female pattern baldness, but the area is diffused.

Alopecia areata

In this condition, patches are diffused all over the scalp and may cover areas like the face and skin. They usually appear in the size of a small coin. In most of the cases, hair comes back. This is caused by a problem with the immune system attacking and damaging the hair follicles. The condition is impermanent, and is more common among people suffering from thyroid and diabetes.

Telogen effluvium

A type of alopecia that spreads out immediately after some triggering events such as childbirth, stress, and hormonal fluctuations. Hair loss occurs 3 months after the event and cover up to 50% of the scalp. This can be resolved when the triggering factor is settled.

Anagen effluvium

Hair loss occurs due to intake or contact with toxins, which rapidly affects 90-95% of hair loss. Chemotherapeutic agents, local radiograph, and poisons such as borax, gold, and bismuth are the main causes of it.

Cicatricial Alopecia (scarring Alopecia)

In this case, hair loss occurs with inflammation, leaving permanent damage with scar formation. In addition, the hair follicles are not visible on that area. Among the causes are physical trauma like burns and radiodermatitis, infections, and cicatricial pemphigoid.
