Androgenetic Alopecia
Mild
Androgenetic alopecia is a common form of hair loss caused by a combination of genetic susceptibility and the effects of androgen hormones on hair follicles. It can affect people of different sexes and usually develops gradually. Hair becomes progressively thinner because affected follicles produce shorter and finer hairs. The pattern varies between individuals, with thinning commonly occurring at the crown or hairline in men and more diffuse thinning over the top of the scalp in women. Early evaluation can help identify treatable causes of hair loss.

When to Seek Medical Attention
Androgenetic alopecia is usually gradual and is not an emergency. Seek medical assessment when hair loss is sudden, rapidly worsening, patchy, associated with scalp inflammation, or accompanied by other symptoms. Evaluation can help distinguish it from other causes of hair loss that may require different treatment.

Overview
Androgenetic alopecia is a common form of hair loss caused by a combination of genetic susceptibility and the effects of androgen hormones on hair follicles. It can affect people of different sexes and usually develops gradually. Hair becomes progressively thinner because affected follicles produce shorter and finer hairs. The pattern varies between individuals, with thinning commonly occurring at the crown or hairline in men and more diffuse thinning over the top of the scalp in women. Early evaluation can help identify treatable causes of hair loss.
Symptoms 1
Joint Stiffness
Causes 2
Androgenetic alopecia results from inherited sensitivity of hair follicles to androgen hormones, particularly dihydrotestosterone. In susceptible follicles, repeated hormone exposure gradually shortens the growth phase and causes progressive miniaturization. Genetic factors can come from either side of the family. Hormonal influences and age also affect how the condition develops. Although androgenetic alopecia is a major cause of patterned hair loss, other conditions can cause similar symptoms, so persistent or unusual hair loss should be assessed before assuming the cause.
Genetics
Hormonal Imbalance
Risk Factors
Risk of androgenetic alopecia is strongly influenced by family history and age. Hormonal sensitivity of hair follicles also plays an important role. The condition can affect people of different sexes, although the typical pattern differs. Hair loss may become more noticeable with increasing age. Other forms of hair loss can coexist, so sudden shedding, scalp inflammation, patchy loss, or rapidly changing symptoms should not automatically be attributed to androgenetic alopecia.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Androgenetic alopecia is usually diagnosed from the pattern and gradual progression of hair loss, medical history, family history, and examination of the scalp and hair. A clinician may use dermoscopy or other methods to examine follicle changes. Laboratory testing is not always necessary but may be considered when symptoms suggest another cause, such as nutritional deficiency, thyroid disease, hormonal abnormalities, or inflammatory scalp disease. Sudden, patchy, painful, or rapidly progressive hair loss warrants evaluation for alternative diagnoses.
Prevention
Key Prevention Tips
Androgenetic alopecia cannot always be prevented because genetic and hormonal factors are central to its development
Avoiding unnecessary traction, harsh chemical treatments, and practices that repeatedly damage hair may help prevent additional hair breakage or traction-related loss
A balanced diet supports normal hair growth, although supplements are not useful unless a deficiency is present
Early assessment of progressive hair thinning can help distinguish androgenetic alopecia from nutritional, hormonal, inflammatory, or other treatable causes
Prevention Guidance
Androgenetic alopecia cannot always be prevented because genetic and hormonal factors are central to its development. Avoiding unnecessary traction, harsh chemical treatments, and practices that repeatedly damage hair may help prevent additional hair breakage or traction-related loss. A balanced diet supports normal hair growth, although supplements are not useful unless a deficiency is present. Early assessment of progressive hair thinning can help distinguish androgenetic alopecia from nutritional, hormonal, inflammatory, or other treatable causes.
