Diagnosing Hair Loss: How is it Done?

Hair loss, a common concern affecting millions worldwide, can be a distressing experience for both men and women. Whether it’s thinning hair, receding hairlines, or bald patches, understanding the root cause of hair loss is crucial for effective treatment. Fortunately, modern medicine offers a variety of diagnostic tools and techniques to help identify the underlying reasons behind hair loss.

Medical History and Physical Examination

The first step in diagnosing hair loss is a comprehensive medical history and physical examination conducted by a qualified healthcare professional, typically a dermatologist or a trichologist. During this assessment, the healthcare provider will ask questions about family history, overall health, medications taken, and lifestyle factors. These questions help to establish any potential genetic predisposition to hair loss and identify possible triggers such as stress, nutritional deficiencies, or underlying medical conditions.

Following the medical history, a physical examination of the scalp and hair will be conducted. The dermatologist or trichologist will closely inspect the scalp, looking for signs of inflammation, redness, scaling, or any other abnormalities that may indicate a specific type of hair loss. They will also examine the pattern and severity of hair loss, which can provide valuable clues about the type of hair loss.


Trichoscopy, also known as dermoscopy of the scalp, is a non-invasive diagnostic tool that has revolutionized the field of hair loss diagnosis. During trichoscopy, a handheld device with magnification and illumination capabilities is used to visualize the scalp and hair follicles in detail. This technique allows the healthcare professional to identify characteristic features of various hair loss conditions, such as patterned hair loss (androgenetic alopecia), alopecia areata (patchy hair loss), and telogen effluvium (temporary hair shedding).

Scalp Biopsy

In certain cases where the cause of hair loss remains uncertain, a scalp biopsy may be recommended. This procedure involves the removal of a small sample of skin and hair follicles from the scalp for further examination under a microscope. A scalp biopsy can help differentiate between different types of hair loss, such as scarring alopecia and non-scarring alopecia, providing valuable information for targeted treatment plans.

Blood Tests

Blood tests play a crucial role in diagnosing hair loss, as they can identify potential underlying factors contributing to hair loss. These tests can measure hormone levels, iron levels, vitamin levels, and markers of inflammation or autoimmune conditions. Identifying deficiencies or imbalances can guide treatment strategies, such as hormone therapy or supplementation.

Pull Test

The pull test is a simple yet effective way to assess the stage and severity of hair loss. During this test, the healthcare professional gently tugs on a group of hairs to determine how many hairs are shed. A positive pull test result (more than 10% of hairs pulled out) may indicate active hair shedding, pointing towards conditions like telogen effluvium. This information can help determine the appropriate course of action for treatment.


A phototrichogram is a specialized diagnostic tool that involves capturing high-resolution images of the scalp and hair follicles. These images are taken at specific intervals to track hair growth and shedding patterns over time. The phototrichogram can be invaluable in assessing treatment effectiveness and monitoring hair regrowth progress.

Diagnosing hair loss involves a combination of medical history, physical examination, and advanced diagnostic techniques. Early and accurate diagnosis is essential for devising effective treatment plans that can slow down or reverse hair loss.
