Hair Loss – Male
Male hair loss is a very common condition, usually caused by male pattern baldness. It typically begins with a receding hairline or thinning at the crown
About hair loss – male
Male pattern hair loss (androgenetic alopecia) is caused by genetically determined sensitivity of hair follicles to the hormone DHT, causing follicles to shrink over time. It's extremely common, affecting most men to some degree by later life, and can begin as early as the late teens or twenties. Other causes include stress, illness, certain medicines and underlying health conditions
Treatments
Symptoms
• A receding hairline, often starting at the temples
• Thinning at the crown or vertex
• Gradual overall thinning across the scalp
• Hair becoming finer and shorter before falling
• Sudden patchy hair loss, scalp redness or pain should be assessed separately, as these suggest a different cause
Diagnosis
Male pattern hair loss is usually diagnosed from its typical pattern and progression on examination, along with family history. Blood tests or scalp examination may be used if an underlying condition or a different type of hair loss is suspected
Treatment
Topical minoxidil and oral finasteride (a 5-alpha reductase inhibitor, or 5-ARI) are the main evidence-based treatments, working by improving blood flow to follicles and reducing DHT levels respectively. Both need continued use, typically for at least 3-6 months, to see and maintain results, and hair loss usually resumes if treatment stops
Prevention and self-care
• Start treatment early if hair loss is a concern, as it's easier to maintain existing hair than regrow lost hair
• Eat a balanced, nutrient-rich diet
• Manage stress
• Avoid excessive heat styling or harsh chemical treatments
• Treat underlying health conditions promptly
• Discuss any concerning or rapid hair loss with a healthcare professional
