Overview
Age, medications, sex, family history, and illness are all risk factors for alopecia. Androgenetic alopecia is more common in males and prevalence increases with age. People with a family history of hair loss are at greater predisposition to developing alopecia compared to individuals who do not have a family history. Psychosocial stress, hormonal imbalance, and illness also increase the risk of alopecia.
Risk Factors
- Some of the specific risk factors for alopecia are as follows:
- Drugs
- Anticoagulants such as heparin, warfarin
- Anticonvulsants such as valproic acid and trimethadione
- Antidepressants such asparoxetine and imipramine
- Beta-blockers such as propranolol
- Medical illness
- Poor hygiene which can predispose to tinea capitis
- Physiological and psychological stress which is associated with telogen effluvium
- Mechanical stressors such as tight braids which is associated with traction alopecia
- Chemicals and hair care products
- Male sex which is at increased risk of androgenetic alopecia
- Age of an individual is also a risk factor. For example, tinea capitis is more common in pediatric populations while the prevalence of androgenetic alopecia increases with age
- Family history of alopecia increases an individual's predisposition to developing alopecia
