Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.
Stress can lead to hair loss by affecting hair-follicle stem cells, and this loss is harder to recover from if one has male pattern baldness (MPB). Treatments like finasteride and minoxidil are used to address hair loss, but stress-related hair loss differs from androgenic alopecia.
The conversation discusses the steps for microneedling, specifically differentiating between medical needling (0.5-1.5mm) and cosmetic needling (0.3mm). It emphasizes the importance of cleaning and disinfecting before microneedling, regardless of needle length.
Finasteride and minoxidil use resulted in a more youthful appearance and improved skin. There is debate about their effects on collagen and skin aging, with no solid evidence supporting significant changes due to finasteride.
Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hair follicles, with tretinoin potentially enhancing its effects by promoting enzyme activity and keratinocyte differentiation. Tretinoin may improve minoxidil's response by boosting the expression of necessary enzymes and transporters.
