Types of Hair Loss: A Comprehensive Guide

Hair loss (alopecia) is a prevalent issue affecting individuals of all ages, both men and women.

Understanding the difference between normal hair shedding and hair loss is critical in identifying possible hair loss conditions. Humans naturally lose about 50 to 100 hairs each day, a phenomenon considered standard hair shedding. However, when shedding surpasses this range, or if hair does not regrow at a similar rate, it may signify a hair loss condition.

In this detailed guide, we will explore different types of hair loss, their causes, symptoms, and treatment options. Gain a better understanding and effectively manage your hair loss condition and find solutions to address this concern.

Androgenetic Alopecia (Hereditary Hair Loss)

Androgenetic alopecia, also known as pattern baldness (male pattern baldness or female pattern baldness), is the most common type of hair loss. It is a gradual condition that develops over time, affecting both men and women.

This type of hair loss is primarily influenced by genetics and hormonal factors, which can lead to a receding hairline, thinning crown, or overall hair thinning.

It usually starts with a noticeable increase in hair shedding and progressively leads to a decrease in hair density and thickness. Symptoms may not be detected until much later in the hair loss process.

Male pattern baldness is usually inherited from either parent and tends to begin in the 20s or 30s. However, many men may experience signs of balding as early as their teenage years.

Female pattern baldness also has genetic origins, but it often occurs much later in life. It typically starts with thinning at the part line and progresses to overall hair thinning all over the scalp. It is most common in women past menopause, when hormone levels decrease significantly.

Treatment options for this type of hair loss may include topical and oral medications, as well as hair transplant procedures. However, the best results come from early diagnosis and treatment.

Telogen Effluvium (Temporary Hair Loss)

Telogen effluvium is a temporary form of hair loss caused by a disruption in the hair growth cycle, leading to an increased number of hairs entering the resting (telogen) phase. Read our post to learn more.

Anagen effluvium (Chemotherapy Hair Loss)

Anagen effluvium is a type of hair loss caused by chemotherapy drugs, which target rapidly dividing cancer cells in the body. Unfortunately, these medications can also damage healthy cells like those found in the hair follicles, leading to sudden and widespread shedding of hair.

Symptoms include thinning and shedding of the scalp and body hair, which may range from mild to severe depending on the dose of chemotherapy drugs used.

If not treated, this condition can lead to severe and permanent hair loss. It is treated with antifungal medications applied directly to the scalp or taken orally.

Symptoms include redness, itching, and hair loss on the affected areas.

Treatment consists of antifungal medications, such as topical creams and oral pills. In addition, anti-inflammatory medications may be prescribed to reduce inflammation and itching on the scalp.

Trichotillomania (Hair Pulling Disorder)

Trichotillomania is a psychological disorder in which a person cannot resist the urge to pull out their own hair, leading to patchy or circular bald spots on the scalp.

It is thought to be caused by a combination of genetic and environmental factors, as well as psychological stressors. Symptoms include an overwhelming urge to pull one’s hair and noticeable patches of missing hair on the head or body.

Traction Alopecia (Hair Loss Due to Tension)

Traction alopecia is a type of hair loss caused by constant tension or pulling on the hair, often due to tight hairstyles or hair extensions.

· Excessive use of hair styling tools


· Gradual hair loss along the hairline or at the site of tension

· Redness, itching, or inflammation of the scalp

Treatment Options

· Avoiding tight hairstyles and allowing the hair to rest

· Topical treatments, such as minoxidil

· Hair transplantation surgery (in severe cases)

Diagnosis of Hair Loss

Diagnosis of hair loss involves a comprehensive examination and evaluation by a healthcare professional.

The process usually starts with a detailed medical history, including questions about current or previous medications, lifestyle, diet, stress levels, and family history of hair loss.

In physical examination of the scalp, doctor will look for signs of inflammation, redness, scaling, or any other abnormalities.

In some cases, a hair pull test is conducted to determine the stage of the shedding process. The doctor gently pulls a small number of hairs (about 100), usually at the end of the scalp, to see how many come out. If more than 3-4 hair strands are dislodged, it indicates active hair shedding.

A scalp biopsy may be necessary if the cause of hair loss is still unclear or if a systemic disease is suspected.

Blood tests might be conducted to check for certain medical conditions often associated with hair loss, such as thyroid disorders or autoimmune diseases. Furthermore, nutritional deficiencies, which can also lead to hair loss, can be identified via blood tests.
