Types of Hair Loss

Hey there dear readers. Today we'll talk about types of hair loss!

Hair loss, medically known as alopecia, is a condition that occurs when the natural hair growth cycle is disrupted. Although hair loss can affect any part of the body, it most commonly affects the scalp, which typically has around 100,000 hairs.

The hair growth cycle consists of three main phases. The first phase is called anagen, during which hair actively grows. This phase can last for several years. The second phase is catagen, a short transitional period when hair stops growing and separates from the follicle, the structure that holds the hair in place beneath the skin. The catagen phase lasts for about 10 days. The third phase is telogen, during which the follicle rests for two to three months before the hair falls out. The next anagen phase begins as new hair grows in the same follicle. On average, most people lose 50 to 100 hairs per day as part of this natural cycle.

However, when this cycle is disrupted or when a hair follicle is damaged, hair loss may occur more rapidly than it can be regenerated, resulting in symptoms such as a receding hairline, patchy hair loss, or overall thinning.

Hair loss can be attributed to various factors, including genetics, medical conditions, and certain behaviors. While genetics play a role in androgenetic alopecia, the most common type of hair loss affecting millions of people, other medical and behavioral conditions can also disrupt the hair growth cycle and lead to hair loss. Dermatologists specialize in diagnosing and treating hair and scalp disorders, and they can help identify the specific type and cause of hair loss.

Here are some common types of hair loss:

Androgenetic Alopecia: Also known as male pattern hair loss or female pattern hair loss, this hereditary condition affects a significant number of men and women in the United States. Medication or surgery can help manage this type of hair loss.

Telogen Effluvium: This type of hair loss occurs when a large number of follicles enter the resting phase of the hair growth cycle, but the subsequent growth phase doesn’t start. Telogen effluvium does not usually lead to complete baldness, but it can cause significant hair shedding and thinning. Various factors such as medical events, conditions, deficiencies, or certain medications can trigger this type of hair loss.

Anagen Effluvium: Rapid hair loss is a result of medical treatments like chemotherapy, which can damage hair follicle production. Hair usually regrows after the treatment ends, and medication can help expedite the regrowth process.

Alopecia Areata: This autoimmune condition occurs when the body’s immune system attacks hair follicles, leading to hair loss in patchy areas. Medication can aid in regrowth, and support groups are available for individuals with this condition

Tinea Capitis: Commonly known as scalp ringworm, this fungal infection primarily affects children and can cause hair loss in circular patches. Early diagnosis and antifungal medication can promote hair regrowth.

Cicatricial Alopecia: This rare type of hair loss involves inflammation that destroys hair follicles, leading to the formation of scar tissue. Hair cannot regrow once scar tissue develops. Treatment options depend on the specific type of cicatricial alopecia.

Hair Shaft Abnormalities: These conditions result in hair strands becoming weak and prone to breakage, causing overall thinning and brittle hairs. Treatment approaches vary depending on the specific hair shaft abnormality.

Understanding the type and underlying cause of hair loss is crucial in determining the appropriate treatment approach. Dermatologists can provide guidance and recommend suitable treatments based on individual circumstances.
