While short-term efficacy has been reported, the safety margins of low-depth yet high-frequency protocols remain incompletely defined. Notably, hair-shaft structural damage has not been systematically described as a complication of microneedling for AGA. Here, we report two patients who developed paradoxical cosmetic deterioration characterized by hair-shaft fragility and breakage following repeated low-depth microneedling, despite an initial favorable response.&lt;/p&gt;&lt;p&gt;Patient 1 was a 37-year-old man with a 3-year history of AGA who underwent weekly microneedling using a 500-μm roller, combined with twice-daily topical 5% minoxidil and oral finasteride (1 mg daily) for 12 months. No topical anesthesia or occlusive dressing was used. Clinical improvement during the first 9 months was reported by the patient and supported by serial clinical photography and trichoscopy, whereas diffuse thinning developed over the final 3 months. Trichoscopy at the time of deterioration revealed anisotrichosis and numerous short, broken hairs consistent with shaft fragility (Figure 1a,b). Concurrent scanning electron microscopy (SEM) demonstrated focal cuticle–cortex delamination, widened inter-scale spaces, and deformation of cuticular plates, consistent with mechanical hair-shaft trauma (Figure 1c).

The treatment utilized a standardized dual-step protocol: manual precision injection targeting the deep dermis, followed by mechanical mesogun injection for uniform superficial coverage. SLEB width and dermal thickness were measured at four facial sites using HFUS before and 1 month after treatment. A skin analyzer assessed skin parameters. A comprehensive clinical evaluation was conducted using the Glogau classification and Global Aesthetic Improvement Scale (GAIS) for efficacy and patient satisfaction assessment.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Post-treatment, HFUS revealed significant reductions in SLEB width (average decrease 29%–47%, all <i>p</i> &lt; 0.001) and increases in dermal thickness (average increase 24%–51%, all <i>p</i> ≤ 0.003). Skin analyzer showed significant improvements in Pores, Wrinkles, Brown Spots, and Red Areas (all <i>p</i> &lt; 0.05). Clinical evaluations confirmed significant improvement in Glogau classification (<i>p</i> &lt; 0.01) and high patient satisfaction (100% reported improvement on GAIS).
