Overview
Male pattern alopecia (MPHL) is a common form of hair loss characterized by progressive thinning of scalp hair, typically starting with a receding hairline and vertex balding, influenced by androgenic hormones. 4Diagnosis
Clinical assessment focusing on pattern of hair loss (receding hairline, vertex balding).
No specific diagnostic tests; evaluation often relies on patient history and physical examination.
Grading systems like the Norwood-Hamilton scale can quantify severity 1.Management
First-line treatments:
- Topical Minoxidil: Applied directly to scalp, typically 2-5% solution/foam (dose varies by product).
- Oral Finasteride: 1 mg daily (evidence supports efficacy in slowing hair loss and promoting regrowth) 4.
Adjunctive treatments:
- Hair Transplantation: Techniques include follicular unit transplantation, micrografts, and minigrafts; outcomes vary but can be natural and aesthetically pleasing 35.
- Novel Devices: Scalp-Tension-Relaxer (STR) apparatus shows promise in promoting hair regrowth through improved scalp hemodynamics and temperature 6.Special Populations
Elderly: Management approaches similar to younger adults, though efficacy may vary; careful consideration of comorbidities and medication interactions is advised 1.
Comorbidities: No specific guidance provided in abstracts; treatment should consider overall health status and potential drug interactions 4.Key Recommendations
Physicians should be comfortable discussing MPHL and recommending treatments, with dermatologists generally more proactive in patient education and resource provision (Evidence: Moderate 1).
Consider the use of finasteride 1 mg daily as a first-line oral treatment for MPHL, supported by evidence of efficacy in clinical settings (Evidence: Strong 4).
For surgical options, follicular unit transplantation techniques can effectively address MPHL with minimized damage to existing hair follicles when performed with magnification systems (Evidence: Moderate 3).
Novel approaches like the Scalp-Tension-Relaxer apparatus may be explored for patients seeking non-surgical interventions, given its reported efficacy in promoting hair regrowth (Evidence: Weak 6).References
